Question

Paragraph: Read the following paragraph and answer the questions given below. Earth is a giant rock-making machine. Rocks form, break apart and then form again. There are three basic groups of rocks. Sedimentary, a group of rocks; is made of small pieces of sand, clay and shells. The weight of water presses down on the sediment until it becomes hard. Igneous rocks are created by heat which are another type of rocks. They start off as magma which is hot, melted rock deep within a volcano. When magma cools and hardens, igneous rock forms. Igneous rock also forms when lava cools. Lava is magma that erupts from a volcano. Metamorphic rocks start as igneous or sedimentary rocks. Heat and heavy pressure cause the rock to undergo a metamorphosis or a change. The new rock often has a different colour. Rocks also change from one form to another and differ from one region to another because of the rock cycle. These changes usually take thousands or millions of years. Q.No.21. How many groups of rocks are mentioned in the paragraph? a) Two b) Three c) Four d) Five Q.No.22. Which line shows that Metamorphic rocks are previously a different type of rock? a) The new rock often has a different colour. b) Examples of metamorphic rocks are slate and marble. c) Metamorphic rocks start as igneous or sedimentary rocks. d) A metamorphosis is a kind of change that something undergoes. Q.No.23. Identify the topic sentence of the paragraph. a) Earth is a giant rock-making machine. b) Lava is magma that erupts from a volcano. c) The new rock often has a different colour. d) These changes usually take thousands or millions of years.​
