Assignment: 14 Subject: - Social Science Class: - VI Teacher: - Mrs. Shilpa Grover Name: ______________ Class & Sec: _______________ Roll No. ______ Date: 23.05.2020 GEOGRAPHY QUESTIONS CHAPTER-2 A. Define the following terms: 1. Equator: It is an imaginary line drawn midway between the North and South Poles. It divides the Earth into two equal parts, the North Hemisphere and the South Hemisphere. 2. Earth’s grid: The network of parallels or latitudes and meridians or longitudes that divide the Earth’s surface into a grid-like pattern is called the Earth’s grid or geographic grid. 3. Heat zones: The Earth is divided into three heat zones based on the amount of heat each part receives from the Sun. These three heat zones are the Torrid Zone, the Temperate Zone and the Frigid Zone. 4. Great circle: The Equator is known as the great circle, as it is the largest circle that can be drawn on the globe. This is because the equatorial diameter of the Earth is the largest. 5. Prime Meridian: It is the longitude that passes through Greenwich, a place near London in the UK. It is treated as the reference point. Places to the east and west of the Prime Meridian are measured in degrees. 6. Time zones: A time zone is a narrow belt of the Earth’s surface, which has an east‒west extent of 15 degrees of longitude. The world has been divided into 24 standard time zones. B. Answer the following Questions: 1. What is the true shape of the Earth? The Earth looks spherical in shape, but it is slightly flattened at the North and South Poles and bulges at the equator due to the outward force caused by the rotation of the Earth. -

We zullen moeten leren omgaan met grotere hoeveelheden water (zeespiegelstijging, grotere rivierafvoeren, extremere hoeveelheden neerslag), maar ook met grotere perioden van droogte. De zomer van 2018 staat wat dat betref nog vers in het geheugen. Beschikbaar zoet water is schaars op wereldschaal. Het meeste water op aarde is zout, en veel van het zoete water zit in gletsjers, of in de ondergrond. Slechts een klein deel is beschikbaar in meren en rivieren. Het IJsselmeer – inclusief Markermeer en Randmeren – is een grote regenton met kost- baar zoet water van prima kwaliteit voor een groot deel van Nederland. Het watersysteem functioneert nog goed, maar loopt wel op tegen de grenzen vanwege klimaatverandering. Door innovatie wegen naar de toekomst verkennen Het is verstandig om ons op die verandering voor te bereiden. Rijkswaterstaat verkent daarom samen met partners nu al mogelijke oplossingsrichtingen die ons in de toekomst kunnen helpen. Dat doen we door te innoveren en te zoeken naar vernieuwende manieren om met het water om te gaan. -

Part V: the Global Positioning System ______
PART V: THE GLOBAL POSITIONING SYSTEM ______________________________________________________________________________ 5.1 Background The Global Positioning System (GPS) is a satellite based, passive, three dimensional navigational system operated and maintained by the Department of Defense (DOD) having the primary purpose of supporting tactical and strategic military operations. Like many systems initially designed for military purposes, GPS has been found to be an indispensable tool for many civilian applications, not the least of which are surveying and mapping uses. There are currently three general modes that GPS users have adopted: absolute, differential and relative. Absolute GPS can best be described by a single user occupying a single point with a single receiver. Typically a lower grade receiver using only the coarse acquisition code generated by the satellites is used and errors can approach the 100m range. While absolute GPS will not support typical MDOT survey requirements it may be very useful in reconnaissance work. Differential GPS or DGPS employs a base receiver transmitting differential corrections to a roving receiver. It, too, only makes use of the coarse acquisition code. Accuracies are typically in the sub- meter range. DGPS may be of use in certain mapping applications such as topographic or hydrographic surveys. DGPS should not be confused with Real Time Kinematic or RTK GPS surveying. Relative GPS surveying employs multiple receivers simultaneously observing multiple points and makes use of carrier phase measurements. Relative positioning is less concerned with the absolute positions of the occupied points than with the relative vector (dX, dY, dZ) between them. 5.2 GPS Segments The Global Positioning System is made of three segments: the Space Segment, the Control Segment and the User Segment. -
Chapter Outline Thinking Ahead 4 EARTH, MOON, AND
Chapter 4 Earth, Moon, and Sky 103 4 EARTH, MOON, AND SKY Figure 4.1 Southern Summer. As captured with a fish-eye lens aboard the Atlantis Space Shuttle on December 9, 1993, Earth hangs above the Hubble Space Telescope as it is repaired. The reddish continent is Australia, its size and shape distorted by the special lens. Because the seasons in the Southern Hemisphere are opposite those in the Northern Hemisphere, it is summer in Australia on this December day. (credit: modification of work by NASA) Chapter Outline 4.1 Earth and Sky 4.2 The Seasons 4.3 Keeping Time 4.4 The Calendar 4.5 Phases and Motions of the Moon 4.6 Ocean Tides and the Moon 4.7 Eclipses of the Sun and Moon Thinking Ahead If Earth’s orbit is nearly a perfect circle (as we saw in earlier chapters), why is it hotter in summer and colder in winter in many places around the globe? And why are the seasons in Australia or Peru the opposite of those in the United States or Europe? The story is told that Galileo, as he left the Hall of the Inquisition following his retraction of the doctrine that Earth rotates and revolves about the Sun, said under his breath, “But nevertheless it moves.” Historians are not sure whether the story is true, but certainly Galileo knew that Earth was in motion, whatever church authorities said. It is the motions of Earth that produce the seasons and give us our measures of time and date. The Moon’s motions around us provide the concept of the month and the cycle of lunar phases. -
Geodetic Position Computations
GEODETIC POSITION COMPUTATIONS E. J. KRAKIWSKY D. B. THOMSON February 1974 TECHNICALLECTURE NOTES REPORT NO.NO. 21739 PREFACE In order to make our extensive series of lecture notes more readily available, we have scanned the old master copies and produced electronic versions in Portable Document Format. The quality of the images varies depending on the quality of the originals. The images have not been converted to searchable text. GEODETIC POSITION COMPUTATIONS E.J. Krakiwsky D.B. Thomson Department of Geodesy and Geomatics Engineering University of New Brunswick P.O. Box 4400 Fredericton. N .B. Canada E3B5A3 February 197 4 Latest Reprinting December 1995 PREFACE The purpose of these notes is to give the theory and use of some methods of computing the geodetic positions of points on a reference ellipsoid and on the terrain. Justification for the first three sections o{ these lecture notes, which are concerned with the classical problem of "cCDputation of geodetic positions on the surface of an ellipsoid" is not easy to come by. It can onl.y be stated that the attempt has been to produce a self contained package , cont8.i.ning the complete development of same representative methods that exist in the literature. The last section is an introduction to three dimensional computation methods , and is offered as an alternative to the classical approach. Several problems, and their respective solutions, are presented. The approach t~en herein is to perform complete derivations, thus stqing awrq f'rcm the practice of giving a list of for11111lae to use in the solution of' a problem. -
World Geodetic System 1984
World Geodetic System 1984 Responsible Organization: National Geospatial-Intelligence Agency Abbreviated Frame Name: WGS 84 Associated TRS: WGS 84 Coverage of Frame: Global Type of Frame: 3-Dimensional Last Version: WGS 84 (G1674) Reference Epoch: 2005.0 Brief Description: WGS 84 is an Earth-centered, Earth-fixed terrestrial reference system and geodetic datum. WGS 84 is based on a consistent set of constants and model parameters that describe the Earth's size, shape, and gravity and geomagnetic fields. WGS 84 is the standard U.S. Department of Defense definition of a global reference system for geospatial information and is the reference system for the Global Positioning System (GPS). It is compatible with the International Terrestrial Reference System (ITRS). Definition of Frame • Origin: Earth’s center of mass being defined for the whole Earth including oceans and atmosphere • Axes: o Z-Axis = The direction of the IERS Reference Pole (IRP). This direction corresponds to the direction of the BIH Conventional Terrestrial Pole (CTP) (epoch 1984.0) with an uncertainty of 0.005″ o X-Axis = Intersection of the IERS Reference Meridian (IRM) and the plane passing through the origin and normal to the Z-axis. The IRM is coincident with the BIH Zero Meridian (epoch 1984.0) with an uncertainty of 0.005″ o Y-Axis = Completes a right-handed, Earth-Centered Earth-Fixed (ECEF) orthogonal coordinate system • Scale: Its scale is that of the local Earth frame, in the meaning of a relativistic theory of gravitation. Aligns with ITRS • Orientation: Given by the Bureau International de l’Heure (BIH) orientation of 1984.0 • Time Evolution: Its time evolution in orientation will create no residual global rotation with regards to the crust Coordinate System: Cartesian Coordinates (X, Y, Z). -
Educator Guide
E DUCATOR GUIDE This guide, and its contents, are Copyrighted and are the sole Intellectual Property of Science North. E DUCATOR GUIDE The Arctic has always been a place of mystery, myth and fascination. The Inuit and their predecessors adapted and thrived for thousands of years in what is arguably the harshest environment on earth. Today, the Arctic is the focus of intense research. Instead of seeking to conquer the north, scientist pioneers are searching for answers to some troubling questions about the impacts of human activities around the world on this fragile and largely uninhabited frontier. The giant screen film, Wonders of the Arctic, centers on our ongoing mission to explore and come to terms with the Arctic, and the compelling stories of our many forays into this captivating place will be interwoven to create a unifying message about the state of the Arctic today. Underlying all these tales is the crucial role that ice plays in the northern environment and the changes that are quickly overtaking the people and animals who have adapted to this land of ice and snow. This Education Guide to the Wonders of the Arctic film is a tool for educators to explore the many fascinating aspects of the Arctic. This guide provides background information on Arctic geography, wildlife and the ice, descriptions of participatory activities, as well as references and other resources. The guide may be used to prepare the students for the film, as a follow up to the viewing, or to simply stimulate exploration of themes not covered within the film. -
Terms for Coordinates Azimuth Angle Measured from North Clockwise
Terms for Coordinates Azimuth Angle measured from north clockwise. North is 0 degrees, east is 90 degrees etc. Three common forms of azimuth exist: true azimuth, magnetic azimuth, and grid azimuth. Angular Coordinates Latitude, Longitude, and Height can specify a location. This is called an angular frame. To obtain angular coordinates in a spherical earth system, only the radius is needed. This is needed only for the height. For an ellipsoidal earth the parameters of the ellipsoid must be specified to convert height and latitude. (To obtain geographic, or mean sea level, height the geoid is needed. Cartesian Coordinates Standard x-y-z coordinates. Three axes perpendicular to each other meet at the origin, or center of the coordinate system. The coordinates of a point are the projection of the location on these axes. Circle, Great A great circle is a circle on the earth whose center is the center of the earth. Alternately, it is the intersection of a plane and a sphere when the center of the sphere is on the plane. Shortest distance between two points on the earth in spherical model is a great circle. Meridians are great circles. Circle, Small A small circle is a circle on the earth whose center is not the center of the earth. Alternately, it is the intersection of a plane and a sphere when the center of the sphere is not on the plane. Parallels of latitude are small circles. Coordinate Frame In general this refers to a Cartesian system of coordinates. The location of the origin and the orientation of the axes with respect to the real earth are also included. -
The History of Geodesy Told Through Maps
The History of Geodesy Told through Maps Prof. Dr. Rahmi Nurhan Çelik & Prof. Dr. Erol KÖKTÜRK 16 th May 2015 Sofia Missionaries in 5000 years With all due respect... 3rd FIG Young Surveyors European Meeting 1 SUMMARIZED CHRONOLOGY 3000 BC : While settling, people were needed who understand geometries for building villages and dividing lands into parts. It is known that Egyptian, Assyrian, Babylonian were realized such surveying techniques. 1700 BC : After floating of Nile river, land surveying were realized to set back to lost fields’ boundaries. (32 cm wide and 5.36 m long first text book “Papyrus Rhind” explain the geometric shapes like circle, triangle, trapezoids, etc. 550+ BC : Thereafter Greeks took important role in surveying. Names in that period are well known by almost everybody in the world. Pythagoras (570–495 BC), Plato (428– 348 BC), Aristotle (384-322 BC), Eratosthenes (275–194 BC), Ptolemy (83–161 BC) 500 BC : Pythagoras thought and proposed that earth is not like a disk, it is round as a sphere 450 BC : Herodotus (484-425 BC), make a World map 350 BC : Aristotle prove Pythagoras’s thesis. 230 BC : Eratosthenes, made a survey in Egypt using sun’s angle of elevation in Alexandria and Syene (now Aswan) in order to calculate Earth circumferences. As a result of that survey he calculated the Earth circumferences about 46.000 km Moreover he also make the map of known World, c. 194 BC. 3rd FIG Young Surveyors European Meeting 2 150 : Ptolemy (AD 90-168) argued that the earth was the center of the universe.
