Question

Answer 1

$\huge\underline{\overline{\mid{\bold{\green{AnSwer}\mid}}}}$

There are three kinds of rock: igneous, sedimentary, and metamorphic.

• Igneous rocks form when molten rock (magma or lava) cools and solidifies.
• Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.
• Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
