5 Major Domains of the Earth Q1. VERY SHORT ANSWERS 1. Name the Strait Between India and Sri Lanka PT-2 ( 2020-21 ) CLASS-VI SOCIAL Ch- 5 Major Domains Of The Earth Q1. VERY SHORT ANSWERS 1. Name the strait between India and Sri lanka. Ans. The strait between India and Sri lanka is Palk Strait. 2. What is continent? Ans. The large landmasses on the Earth are known as continents. 3. What are the main gases that comprises atmosphere? Ans. The main gases are Nitrogen, Carbon dioxide, Oxygen, Argon etc. 4. Why is Australia called an ‘Island Continent’? Ans. Australia is known as an island continent because it is bound by oceans and seas by all sides. 5. Why is Europe called as peninsula? Ans. Europe is a peninsula as it is surrounded on three sided by water. 6. Name the deepest point of the Pacific ocean and Atlantic ocean. Ans. Pacific ocean –Challenger Deep located in the Mariana Trench Atlantic ocean – Milwaukee Deep located in the Puerto Rico Trench. 7. What is Atmosphere? Ans. The layer of air that surrounds our earth is called the atmosphere. 8. What is Biosphere? Ans. Biosphere is the narrow zone of contact between the lithosphere, the hydrosphere and the atmosphere. The life forms exist in this sphere. 9. What are biomes? Ans. In the biosphere, living things form communities based on their physical surroundings. These communities are referred to as biomes. 10. What is the basis of division of atmosphere? Ans. The basis of division of atmosphere is composition, temperature and other properties. Q2. SHORT ANSWERS- 1. Why there is no permanent settlement in Antarctica? Ans. Antarctica is located in the South Pole region, which is permanently covered with thick ice sheets. The extreme cold condition makes the region without any settlement. 2. Define the words Isthmus and Strait. Ans .Isthmus - A narrow strip of land that joins two landmasses. Strait – A narrow stretch of shallow water which connects two large water bodies like seas and oceans. 3. Why is the Atlantic ocean world’s busiest ocean in terms of commerce? Ans. The indented and irregular coastline provides ideal condition for harbours and ports, which makes the region suitable for carriage of goods and transportation. 4. What is global warming and how can it be disastrous? Ans. The increasing amount of CO2 ( carbon dioxide ) leads to increase in global temperature. This is termed as global warming. The rising temperature results in increasing natural calamities which could be turned into disaster. 5. How can environment be protected? Ans. The environment can be protected in a manner if we use the natural resources in limited way and do not harm or pollute any of the domains of the earth to maintain the balance of nature between the domains of the lithosphere, the atmosphere and the hydrosphere. ASSIGNMENT On the outline map of world mark the following: • Seven continents • Five oceans • Isthmus of Panama • Rocky mountains • Andes mountains • Sahara desert • Himalayas • Amazon river .

    The World Factbook Oceans :: Atlantic Ocean Introduction :: Atlantic Ocean Background: The Atlantic Ocean is the second largest of the world's five oceans (after the Pacific Ocean, but larger than the Indian Ocean, Southern Ocean, and Arctic Ocean). The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic access waterways. The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth world ocean, the Southern Ocean, removed the portion of the Atlantic Ocean south of 60 degrees south latitude.

  • Convective Mixing by Internal Waves in the Puerto Rico Trench
    Journal of Marine Research, 74, 161–173, 2016 Convective mixing by internal waves in the Puerto Rico Trench by Hans van Haren1,2 and Louis Gostiaux3 ABSTRACT A 2.4 km long deep-sea mooring was deployed for 14 months in the Puerto Rico Trench, the deepest part of the Atlantic Ocean. Below its top buoyancy package, the mooring line held a 200 m long string of high-resolution temperature sensors and a current meter. Over the instrumented range between 6,004 and 6,204 m, waters are very weakly stratified, with local buoyancy frequency equaling about 1.9 times the semidiurnal tidal frequency. Besides quiescent waters, the detailed observations show regular vertical turbulent overturning associated with periodic warming and driven by internal tidal and inertial waves. During such episodes, the 4-day and 200 m vertically averaged dissipation rate increases from approximately 10−11 up to 10−9 m2 s−3, and eddy diffusivity increases from 5 × 10−5 up to 4 × 10−3 m2 s−1. No large-scale shear-driven Kelvin-Helmholtz billows are observed, and free convection seems the dominant primary turbulent overturning mechanism affecting material redistribution and life in the weakly stratified environment. Keywords: High-resolution temperature observations; Puerto Rico Trench; deep-ocean convection in weak stratification 1. Introduction As the ocean is basically stably stratified in density from surface to bottom, vertical (“diapycnal”) turbulent exchange is hampered (Gargett 1984), but not blocked. In fact, open oceans’ weak vertical turbulent exchange is still 100-fold larger than molecular dif- fusion (Gregg 1989). In the strongly stratified portions of open seas and oceans away from boundaries, the main process behind diapycnal exchange is shear instability of (partially) opposing currents above and below the pycnocline in combination with (the sparse break- ing of) high-frequency internal waves supported by the same stratification (e.g., Geyer and Smith 1987; Seim and Gregg 1994).

  • Caribbean Earthquakes and Hurricane Technical Report by Dr
    Caribbean Earthquakes and Hurricane Technical Report By Dr. Frank J. Collazo March 24, 2010 Acknowledgment Ms. Billie Foster edited, formatted, and provided the necessary support required to finish the report. Dr. Tony DiRienzo contributed to the report the technical description of the Richter Scale used as a tool to measure the magnitude of earthquakes since 1935. Dr. DiRienzo has provided several examples showing the effects of parametric changes of the equation that impacts the magnitude of the earthquake and its effects. Introduction The purpose of this report is to assess what is the best area to invest in a commercial enterprise with minimum risk of being exposed to hurricanes and earthquakes. There are three areas addressed in this report: Costa Rica, Dominican Republic and Puerto Rico. The stability of the governments of Costa Rica and Dominican Republic have been scrutinized and analyzed. Costa Rica is exposed to earthquakes, volcanoes and hurricanes. Costa Rica's governance and economy have been stable for over 60 years. Costa Rica has had ten earthquakes (3.0 to 7.6) for the period December 12, 2009 to 24 January, 2010. The Dominican republic is exposed to hurricanes, frequent mild earthquakes, and Tsunamis. The Dominican Republic has won the Turismo first place in the Caribbean since 2007, previously held by Puerto Rico. The Dominican Republic ha had two major earthquakes (8.0 and 1.3 magnitude) in 1946 and 2003. Puerto Rico had four major earthquakes (1670, 1787, 1867, and 1918) and several major hurricanes. Puerto Rico had several minor earthquakes below a magnitude of 3.0.
