  • PRIME MERIDIAN a Place Is
    Lines of Latitude and Longitude help us to answer a key geographical question: “Where am I?” What are Lines of Latitude and Longitude? Lines of Latitude and Longitude refer to the grid system of imaginary lines you will find on a map or globe. PARALLELS of Latitude and MERIDIANS of Longitude form an invisible grid over the earth’s surface and assist in pinpointing any location on Earth with great accuracy; everywhere has its own unique grid location, and this is expressed in terms of LATITUDE and LONGITUDE COORDINATES. Lines of LATITUDE are the ‘horizontal’ lines. They tell us whether a place is located in the NORTHERN or the SOUTHERN HEMISPHERE as well as how far North or South from the EQUATOR it is. Lines of LONGITUDE are the ‘vertical’ lines. They indicate how far East or West of the PRIME MERIDIAN a place is. • The EQUATOR is the 0° LATITUDE LINE. o North of the EQUATOR is the NORTHERN HEMISPHERE. o South of the EQUATOR is the SOUTHERN HEMISPHERE. • Lines of Latitude cross the PRIME MERIDIAN (longitude line) at right angles (90°). • Lines of Latitude circle the globe/world in an east- west direction. • Lines of Latitude are also known as PARALLELS. o As they are parallel to the Equator and apart always at the same distance. • Lines of Latitude measure distance north or south from the equator i.e. how far north or south a point lies from the Equator. • The distance between degree lines is about 69 miles (or about 110km). o A DEGREE (°) equals 60 minutes - 60’.

  • 307 Lesson 21: Eratosthenes' Measurement of the Earth the Most
    307 Lesson 21: Eratosthenes’ Measurement of the Earth The most important parallel of latitude is the equator; it is the only parallel of latitude that is a great circle. However, in the previous lesson we learned about four other parallels of latitude which are of great importance because of the relative geometry of the Earth and the Sun. These are the Tropics of Cancer and Capricorn and the Arctic and Antarctic Circles. We briefly review the basic facts about these four parallels. At each moment on the day of the summer solstice, there is a single point on the surface of the Earth that is closet to the Sun. As the Earth rotates through the day of the summer solstice, this closest point to the Sun moves around the surface of the Earth and traces a parallel of latitude called the Tropic of Cancer. Another description of the Tropic of Cancer is that it is the set of all points on the Earth’s surface where the Sun is directly overhead at solar noon on the day of the summer solstice. The latitude coordinate of the Tropic of Cancer equals the measure of the angle that the Earth’s axis makes with the perpendicular to the ecliptic plane: approximately 23.5º N. On the day of the summer solstice, as the Earth rotates about its axis, the terminator (the division between daytime and nighttime) moves, and its northernmost point traces out a parallel of latitude called the Arctic Circle. Similarly, as the Earth rotates, the southernmost point of the terminator traces out a parallel of latitude called the Antarctic Circle.

  • North Pole • South Pole
    Divisions of the Earth The Earth can be divided in many ways. Today, we will learn about the seven most important divisions on the planet: • equator • northern hemisphere • southern hemisphere • tropic of Capricorn • tropic of Cancer • North Pole • South Pole Let’s find out more! Equator • The equator is an imaginary line that divides the Earth in half. • The equator is an equal distance between the North and South Poles. • The weather on the equator is hot all year round. • At the equator, day and night are both 12 hours long. Did You Know? Although the weather is generally hot, there is a mountain on the equator where you can ski! Challenge Question Why do you think places at the equator are hot? Northern Hemisphere • The part of the Earth north of the equator is called the northern hemisphere. • 80% of the world’s population lives in the northern hemisphere. • 90% of land is in the northern hemisphere. • The northern hemisphere includes all of north America, Europe and most of Asia and Africa. Southern Hemisphere • The part of the Earth south of the equator is called the southern hemisphere. • Only 20% of the world’s population lives in the southern hemisphere. • 90% of the planet’s water is in the southern hemisphere. • The southern hemisphere includes all of Australia, Antarctica and most of South America. Did You Know? When it is winter in the southern hemisphere, it is summer in the northern hemisphere! Tropic of Cancer • The tropic of Cancer is an imaginary line in the northern hemisphere. • It is also called the northern tropic.

  • “The Story of the Seasons”
    “The Story of the Seasons” The Earth takes 365 and 1/4 days to complete one revolution around the sun and this amount of time is called a “year.” Every four years, 1/4 of a day will add up to 24- hour day, and we add an extra day (February 29th) to the calendar. This is why we have a “leap year” with one extra day every four years. The Earth’s orbit is nearly circular (or slightly elliptical) and Earth is actually closer to the sun during the northern hemisphere’s winter months. Summer On the first day of summer, June 20 or 21st, the Earth’s Northern Hemisphere is tilted 23.5° toward the sun. The day is known as the summer solstice. On this day the sun is at its highest point in the Northern Hemisphere sky at noon and directly over the Tropic of Cancer (the 23.5°N parallel of latitude). Solstice means “sun stop” in Latin. When the Northern Hemisphere is tilted toward the sun, that part of the Earth receives more direct rays of sunlight during the daytime than the Southern Hemisphere does. The Southern Hemisphere is tilted away from the sun and therefore, receives the sun’s rays at an angle. As a result, it is summer in the Northern Hemisphere and winter in the Southern Hemisphere. Conversely, during our winter months when the Northern Hemisphere is tilted away from the sun, it is summer in the Southern Hemisphere. During the summer, the land, oceans, and atmosphere in the Northern Hemisphere receive more direct rays of sunlight.

  • Energy in the Atmosphere Energy from the Sun
    Energy in the Atmosphere Energy From the Sun • Travels in electromagnetic waves. • Reaches Earth in the form of: ○ visible light - ROYGBIV spectrum ○ infrared radiation - not visible; felt as heat ○ ultraviolet (UV) radiation - cause sunburns, skin cancer & eye damage The Sun’s Light We See ● Scattered by gas in the atmosphere ○ Scattering: Reflection of light in all directions ● Short waves (violet) scatter easier than long waves (red) ○ Daytime sky is blue because atmosphere scatters (reflects) blue light ○ Sunrise/Sunset: Light travels through thicker atmosphere, which removes blue light; remaining light is orange & red How Heat is Transferred • Radiation: transfer of energy as electromagnetic waves. • Conduction: transfer of thermal energy through contact. • Convection: transfer of thermal energy by the circulation of a liquid or gas. The Greenhouse Effect • Gases in the atmosphere absorb thermal energy and radiate it back to Earth. Global Warming • More greenhouse gases in the atmosphere may be the cause of global warming. Why Air Moves • Air Moves Due To Uneven Heating by the Sun: ○ Hot air at Equator rises, then sinks at the poles. ○ Cold polar air then flows toward the equator. Why Air Moves • Pressure Belts Are Found Every 30º ○ 30º N - Tropic of Cancer ○ 30º S - Tropic of Capricorn ○ 60º N - Arctic Circle ○ 60º S - Antarctic Circle The Coriolis Effect • The Coriolis Effect: The apparent curving of the path of wind currents due to the Earth’s rotation. 1835 – Gaspard Gustave Coriolis observed and calculated veering effect mathematically Global Winds Types of Global Winds • Polar Easterlies - wind from the poles to 60° latitude in both hemispheres.
