The physical processes that create most of earth's physical features including mountains are known as
a. accretion
b. subduction
c. continental drift
d. plate tectonics

D. Plate tectonics

The reason why answer choice "D. Plate tectonics" would be the correct answer because this was the physical process that created most of earth's physical features such as mountains.

The physical processes that create most of earth's physical features including mountains are known as plate tectonics.

A lot of the mountains you see today are formed by plate tectonics. What this means is that the plates that are beneath the earth's surface "hit" or "smash" each other, which makes an impact above the earth's surface.

The tectonic plates could be hitting each other while the ground in the surface starts "shoving" together and getting taller, which results as mountains you see today.
