Q

Magma

A

Magma is the name given to the melt rock masses inside the Earth or other planets. They are usually composed of a mixture of liquids, volatile and solids

Q

Sedimentary rock

A

Natural forces break rocks into smaller rocks. Forces as rushing water wear away bits of rock. These small pieces are the sedimentary rocks.

17
Q

Texture (in rocks)

A

The texture of a rock is the size, shape, and arrangement of the grains (for sedimentary rocks) or crystals (for igneous and metamorphic rocks)

18
Q

Weathering

A

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth.
