Q: Name the two rock series of two main geological ages in which coal occurs.

In India, coal occurs in rock series of two main geological ages. The Gondwana coal was formed over 200 million years ago. The tertiary deposits are about 55 million years old. The major sources of Gondwana coal are located in the Damodar valley (West Bengal-Jharkhan). In this belt, Jharia, Raniganj and Bokaro are important coalfields. Coal deposits are also present in the Godavari, Mahanadi, Son and Wardha valleys. Tertiary coal is found in the north-eastern states of Meghalaya, Assam, Arunachal Pradesh and Nagaland.

Question 1

Explain the three types of plates and write the effects of the movements of plates.

Accepted Answer

The plate movements are classified into three types:(i) Some plates come towards each other and form convergent boundaries.(ii) Some plates move away from each other and form divergent boundary.(iii) At times, they may also move horizontally past each other and form transform boundary.When two plates come together, they are known as convergent plates. They are also known as constructive plates. When two plates move far away from each other, they are known as divergent plates. When two plates coming towards each other collide or burst pass, they are known as transform plate. The movement of plates causes volcanic eruptions, earthquakes, formation of mountains, etc.

Question 8

Why are tropical rainforests found near the equator?

Accepted Answer

Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. Most tropical rainforests fall between the Tropic of Cancer and the Tropic of Capricorn.These areas receive more sunlight and the amount of sunlight and intensity of the sunlight the tropics receive doesn't vary much in comparison to other parts of the globe. The high temperatures means that evaporation happens at a fast rate, resulting in frequent rainfall.
