What are the kinds of rocks?

Answer 1

All rocks are solid. Igneous, metamorphic, or sedimentary.

Answer 2

There are three main types of rock, igneous, sedimentary, and metamorphic.

Igneous rocks are the type formed from the cooling of molten rock as either magma or lava. Sedimentary are formed from the compression of sediment over periods of time. Finally, metamorphic rocks are formed by the application of heat and pressure over long periods of time.

Answer 3

The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks.

Igneous rocks cool from magma or lava.

Sedimentary rocks form by the deposition of particulates and silt.

Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.

Answer 4

The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks are formed from cooled and solidified magma or lava. Sedimentary rocks are created from the accumulation and compression of sediments. Metamorphic rocks are formed by the transformation of existing rock types through heat, pressure, or chemical processes.
