Question

Distinguish between sedimentary and igneous rocks.​

Answer 1

Answer:

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.

Answer 2

Answer:

1. Igneous rocks form when molten rock (magma or lava) cools and solidifies.
2. Igneous rocks solidify from molten rock (called magma within the Earth and lava on the surface).

1. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.
2. Sedimentary rocks are layered.
