differences in air pressure on Earth

When the sun’s energy is transferred to the earth’s surface, it hits the area around the north and south poles most directly, while hitting the area around the equator at an angle.

When the sun’s energy is transferred to the earth’s surface, it hits the area around the equator most directly, while hitting the areas around the north and south poles at an angle.

The earth’s surface is evenly heated.

None of the above

Warm air rises from the equator and moves toward the poles because it is less dense.

Warm air rises from the equator and moves toward the poles because it is more dense.

Warm air rises from the north and south poles, then sinks toward the equator because it is less dense.
