Question

according to the text, where does seafloor spreading primarily occur?
answer: explain:
a. mid - ocean ridges
b. subduction zones
c. continental margins
d. transform boundaries
question:
the passage describes the movement of tectonic plates as a dynamic and ongoing process. based on this description, which of the following inferences can be made about the earths surface in the distant future?
answer: explain:
a. mountain ranges will erode and disappear entirely.
b. the earths surface will eventually become static and unchanging.
c. volcanic and earthquake activity will

Explanation:

Seafloor spreading occurs primarily at mid - ocean ridges where new oceanic crust is formed as tectonic plates move apart. For the second question, since tectonic plate movement is dynamic and ongoing, volcanic and earthquake activity will continue as these are associated with plate interactions. Mountain ranges may erode but not disappear entirely, and the Earth's surface will not become static.

Answer:

A. Mid - ocean ridges
C. Volcanic and earthquake activity will continue.
