In continuing to think about the rock cycle, we know the phases can take thousands, even millions of years to occur. Which stage in the cycle can happen in mere hours or days? a. Lithification and Erosion
b. Heat and pressure
C. Compaction and weathering
d. Cooling & Crystallization

d. Cooling & Crystallization

Explanation:

One of the stages of the rock cycle that can take place under mere hours or days is cooling and crystallization.

Cooling and crystallization of lava on the earth surface is a very rapid and fast process.

When magma from within the earth reaches the surface, it becomes lava. Due to the nature of the surface, it cools rapidly and very fast to form very fine grained igneous rocks.
