(iii) Name three types of rocks.

Answer: The three types of rocks are

• Igneous Rocks
• Sedimentary Rocks
• Metamorphic Rocks

(iv) How are extrusive and intrusive rocks formed?

Answer: The molten lava comes out of volcanoes, reaches the earth’s surface and cools down rapidly to become a solid piece of rock. This is how extrusive rocks are formed. For example, basalt.

When the molten lava solidifies deep inside the earth’s crust, the rocks so formed are called intrusive rocks. For example, granite.

(v) What do you mean by a rock cycle?

Answer: The process of transformation of rocks from one type to another due to changes in certain conditions in a cyclic manner is called a rock cycle.

(vi) What are the uses of rocks?

Answer: Rocks are useful for various purposes, such as

• They help in making roads.
• They are used in the construction of houses and buildings.
• Small stones are used by children in different types of games.
• They are used in fertilisers.

(ii) Sedimentary rocks are formed from sediments.

Answer: The small fragments of rock that hit each other and break to reach the ground are called sediments. These sediments are transported and deposited by wind, water, etc., and then compressed and hardened to form a layer of rocks called sedimentary rocks. This shows that sedimentary rocks are formed from sediments.
