Which factors control the cooling time of magma within the crust? Choose one or more:
A. the rate at which heat is absorbed from the surroundings
B. surface water passing over the magma
C. the depth at which the magma cools
D. the volume of the intruded magma
E. the heat difference between the magma and the surface

B.

C.

Explanation:

Factors control the cooling time of magma within the crust include surface water passing over the magma and the depth at which the magma cool.

Surface water passing over the magma absorbs the water and carries away heat and magma present in depths is cooler than surface because magma rises to earth surface due to high pressure and that is hot.

Hence, the correct option is "B. and C."

the answer is "c" im pretty sure.
