3. Some scientists theorize that continental movements may cause climate changes by _____.

A. altering the makeup of the troposphere
B. redistributing Earth’s vegetation
C. shifting the equatorial and temperate zones
D. changing patterns of ocean currents

C. shifting the equatorial and temperate zones

The correct answer is C. shifting the equatorial and temperate zones. Continental movements can cause changes in the distribution of landmasses, which in turn can impact the location of equatorial and temperate zones. This shifting of zones can result in climate changes, such as changes in temperature and precipitation patterns.
