Question

what natural process is responsible for shaping mountains and valleys over time?
a. erosion
b. photosynthesis
c. condensation
d. precipitation
which process is responsible for shaping the geosphere through the movement of earth’s plates?
a. evaporation
b. photosynthesis
c. sedimentation
d. plate tectonics

Explanation:

First Question:

Erosion (like water, wind, ice) wears down mountains and forms valleys over time. Photosynthesis is for plants, condensation is water vapor to liquid, precipitation is rain/snow—none shape landforms like erosion.

Plate tectonics is the theory of Earth’s plates moving, causing mountains, earthquakes, etc., shaping the geosphere. Evaporation is water cycle, photosynthesis is plant process, sedimentation is sediment deposit—unrelated to plate movement.

Answer:

a. Erosion
