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".
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

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.
