Question

How does erosion affect igneous rocks?

Answer 1

Hint: Three types of rocks have been formed from volcanic eruption on the Earth; these are igneous rocks, sedimentary rocks and metamorphic rocks.

Complete answer:
The volcanic eruptions produce a great amount of molten lava and magma. These molten lava and magma when cools down and get solidified on the surface of the Earth, results in the formation of rocks called igneous rocks. As formed from magma, they are also called magmatic rocks.
Erosion is one of the most common phenomena on the Earth. It is the unusual and rapid process of deteriorating or breaking the surface of Earth that consists of plants, rocks and trees. Erosion happens through wind, soil and water.
The erosion conditions on the Earth’s surface results in the formation of sediments of igneous rocks. With continuous soil or wind erosion, the igneous rocks first break into small sediments and then convert into mud or sand. Similarly, erosion through water also breaks down the igneous rocks and makes them deposit in the waterbeds or near the water surface.
Apart from change in their physical properties, these rocks also get carried away to far places when erosion occurs by wind or water. This results in the relocation of igneous rocks.
Hence, erosion affects the igneous rocks by changing its shape, size, texture and location.

Note:
Apart from the changes that igneous rocks undergo through erosion, sedimentary and metamorphic rocks also undergo the same changes when they get through erosion.
