Question

guided practice
which causes winds to blow over the surface of earth?
a. uneven warming by the sun
b. the water cycle
c. infrared radiation
d. fast - flowing rivers

Explanation:

Wind forms because the sun heats Earth's surface unevenly. This creates differences in air pressure; air moves from high-pressure (cooler) areas to low-pressure (warmer) areas, which is experienced as wind. The other options are not direct causes of wind: the water cycle relies on solar energy but does not drive wind, infrared radiation is a form of solar energy transfer, and fast-flowing rivers are unrelated to wind formation.

Answer:

A. uneven warming by the sun
