Major Temperature Zones of the Earth
(My World and I)
A. Fill in the blanks.
1. The torrid zones is situated between the two tropical regions.
2. The Frigid zones lie at the extreme north of the northern hemisphere and the extreme south of the southern hemisphere.
3. The Temperate zones are between the two tropics and the Arctic and Antarctic Circles.
4. The areas between 10°N and 10°S are called the Equatorial regions.
5. The areas between 15° and 25° north and south of the equator are called the Tropical regions.
B. Write true or false:
1. The equatorial regions have the largest variety of plants and animals. [F]
2. Antarctica is part of the temperate zone. [F]
3. Permanently frozen parts of the frigid zone are called polar ice caps. [T]
4. The northern and southern temperate and frigid zones have exactly the same mammals. [F]
C. Draw three columns in your notebook as shown and put the words from the box in the right columns.

1. Why are the temperature Zones also called heat zones?
= The different temperature zones are also called heat zones because the heat in each of these zones depends on how far it is form the equator. The climatic zones near the equator are the hottest. As we more away from the equator, the climatic zones are near the poles.
2. Desert areas have very few cities. Why is this?
= Different areas have very few cities due to the hot and dry climate and scarcity of rain. These are hardy plants, adapted with fleshy stems, thorny and tiny leaves, long roots and strong seeds.
3. Write one or two sentences about A. Desert plants and B. Coniferous trees.
= A. Desert plants : The plants of desert region, are hardy, adapted with fleshy stems, thorny and tiny leaves, long roots and strong seeds.
B. Coniferous trees : Coniferous trees are tall straight cone-bearing trees with niddle-like leaves like pine, fir etc.
4. Why is farming not possible in the frigid zone?
= The regions in the frigid zone around the poles are permanently frozen. The region around the North Pole is frozen water, whereas in the South Pole it is frozen land. So, due to this reason, farming is not possible in the frigid zone.
5. Explain why the numbers of bison in North America were greatly reduced.
= In the temperate zone, large areas of grasslands were converted into farmland as well as towns and cities for people to live. Animals like mighty bison of North America that lived three in thousands, were reduced to very small numbers.
