question 10 of 28
how do plate tectonics shape earths surface?
a. the movement of plates causes earths surface to slowly expand.
b. the movement of plates causes continents on earth to change shape and size.
c. the movement of plates causes continents on the surface of the oceans to float apart.
d. the movement of plates causes the diameter of earth to gradually decrease.

Explanation:

Plate tectonics involves the movement of Earth's lithospheric plates. This movement leads to processes like continental drift, which causes continents to change shape and size over geological time - scales. Earth's surface area doesn't expand or contract significantly due to plate movement, and continents don't float on the surface of oceans in the way described in option C. Also, the diameter of Earth doesn't gradually decrease because of plate tectonics.

Answer:

B. The movement of plates causes continents on Earth to change shape and size.
