Question
Explain the Rock cycle.
✓
Answer
When the hot and liquid magma cools down and becomes solid, it forms igncous Scanned wrocks.
The igneous rocks turn into smaller particles, are transported from one place to another and form sedimentary or stratified rocks.
Due to extreme high temperature and pressure, the igneous or sedimentary rocks are transformed into metamorphic rocks. Due to the high temperature and pressure, thesc rocks melt and again become hot liquid magma.
This hot magma again cools down and solidifies into igneous rock again. Thus, under certain conditions, one type of rock transforms into another type of rock in a cyclic manner. This process is known as 'Rock Cycle'.
