A rock is found in an area that once had an active and has since been affected by erosion. The rock has individual black and white crystals that are easy to see. Which other description fits the rock?

The other description of the rock is that it's cooled in the volcano. The type

of rock is known as the igneous rock.

Igneous rock is produced when the volcano erupts and is cooled near the

Earth's surface. We were told that the rock was affected by erosion which

took it deep into the soil and became inactive.

High temperature and pressure led to it erupting as a volcano which

explains why it has the black and white color due to heat exposure.

exposed to air and water

Explanation:

A rock found in an area that was active once and affected by erosion is a form of sedimentary rocks. Sedimentary rocks can be present in black and white crystals form.

The other description fits the sedimentary rocks is exposed to air and water. Sedimentary rocks are formed by the process of erosion and weathering that include the exposure of rocks to the wind and rain or water, that break down large pieces of rocks into smaller.

Hence, the correct answer is "exposed to air and water".
