Question

what leads to the formation of a windchill factor?
earths rotation influences air movement along a curved path.
air flows steadily from different directions at certain wind speeds.
warm air rises when an area of high pressure is present over land.
there is a change in air temperature and increase in high wind speeds.

Explanation:

Windchill factor describes how cold wind makes humans feel, caused by wind removing the warm air layer around the body faster. It depends on both low air temperatures and increased wind speeds, which enhance heat loss from the skin. The other options describe unrelated atmospheric phenomena: Earth's rotation affects Coriolis effect, steady multi-directional air flow is not linked to windchill, and warm air rising from high pressure is a general pressure system behavior.

Answer:

D. There is a change in air temperature and increase in high wind speeds.
