Question

Differentiate between the characteristics of igneous rock and
sedimentary rock.​

Answer 1

Igneous rocks mainly have a crystal-like structure. Sedimentary rocks have a fragmentary structure and contain an inner layering called bedding. Metamorphic rocks are very hard and may appear to be banded or layered. The texture of igneous rocks depends on how fast it has cooled down.

Answer 2

Igneous rocks are derived from molten material (magma or lava). Sedimentary rocks are derived from sediments of pre-existing rocks, fossils, and tiny pieces of animal remains. Metamorphic rocks are derived from other rocks. Igneous rocks are formed when molten material from volcanoes cools down and solidifies.
