Question

What processes can change igneous rock into sedimentary rock?

Answer 1

Types of Rocks

There are three different types of rocks found on earth. Igneous rocks are made from lava that has cooled; sedimentary rocks are made of mud and organic material, and metamorphic rocks have been changed deep in the Earth's crust by heat and pressure.

Answer and Explanation:

The process of erosion and depositing rock grains (also known as sedimentation) can change igneous rock into sedimentary rock. As igneous rock is weathered away by rain, wind, or plants and animals, the rock grains can become sedimentary rock by settling at the bottom of a body of water. Over millions of years, the layers of the sea floor will become hardened by the water pressure, turning into sedimentary rock.

Answer 2

Weathering and erosion break down the igneous rock  and can change igneous rock into sedimentary rock.

Explanation:

Different types of rocks which are found on earth are of three types

• Igneous rocks are formed by the lava which gets cooled;
• Sedimentary rocks are those which are formed  by mud and organic material,
• Metamorphic rocks are those rocks which are formed and have been changed deep inside the Earth's crust with the heat and pressure.
• During the process of change of igneous rock into sedimentary rocks there takes place erosion and depositing rock grains.
• These rocks are weathered by rain, wind or plants and animals and then  the rock grains can be converted to sedimentary rock by simple settling at the bottom of a body of water.

• Weathering and erosion break down the igneous rock into pebbles, sand, and mud, and thus creates sediment, which in turn accumulates in basins on the Earth's surface.
