26. what causes a volcanic eruption? a. mining nearby b. rapidly changing temperatures c. pressure changes…

Brief Explanations:

Volcanic eruptions occur due to pressure - related processes in the Earth's crust. Magma rises through cracks or vents in the crust when pressure changes allow it to move upwards and eventually erupt. Mining nearby does not cause eruptions in a fundamental way, and rapidly changing temperatures are not the main cause. We know the cause is related to crustal pressure changes.

Answer:

C. pressure changes in the Earth's crust
