Answer 2

A naturally occurring mass made up of a mineral or a mixture of minerals is known as rock. Igneous, metamorphic, and sedimentary rocks are the three basic types of rocks.

Explanation: The Rock cycle is a series of events that allow sedimentary, igneous, and metamorphic rocks to shift from one type to another by melting, cooling, eroding, compacting, and deforming.

• Igneous rock is the primary rock that forms as magma cools. Extrusive igneous rock is formed when lava cools near the earth's surface. Intrusive igneous rocks occur as magma cools down deep inside.
• When wind and water interact with rocks on the earth's surface, they become weathered and eroded. These rocks break down into smaller fragments known as sediments.
• These sediments are deposited, and the shattered material is hidden by new material as it accumulates. These fragments are gradually crushed into new types of rocks by the weight of overlying sediments during the lithification process.
