Question

Explain rock cycle.

Answer 1

Instructions:

• Explain how different types of rock are formed
• State how they can transform into one another.

Solution:

• Igneous rocks are the primary rocks formed first on the earth.
• These rocks are weathered, eroded, transported and deposited at some places to form sedimentary rocks.
• The Igneous and Sedimentary rocks are changed into metamorphic rocks under the influence of temperature and pressure.
• The metamorphic rocks are also disintegrated and deposited to form sedimentary rocks.
• Metamorphic and sedimentary rocks melt when they experience intense heat and form igneous rocks.
• Like this, the rocks of the earth's crust keep on changing from one form to another form under various natural forces and agents.
• This endless process is referred to as the Rock Cycle
