Which change would most likely occur if this rock became buried deep within earth’s crust and was subjected to intense heat and pressure, but did not melt?

Does you question have the following choices?

A) The density of the pebbles and sand would decrease.

B) The rock would become a plutonic rock composed mostly of quartz.

C) The rock would become more felsic with a higher concentration of magnesium.

D) The pebbles would become distorted and the sand would be recrystallized.

If so, then the answer is letter D.

Ithink its c hope it : )

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
