Michelle drew a simple diagram to show how a hurricane forms. Which location on the diagram indicates a low-pressure area?

inysia [295]

Answer:

"Location 4" indicates a low-pressure area

Explanation:

A low-pressure area is defined as the region in which the pressure in the atmosphere is comparatively lesser than nearby surrounding areas. This region is a depression that is comprised of more winds, warmer air, and lifting of air mass takes place.

In a low-pressure zone, the warm air becomes less dense, due to higher temperature, as a result of which it rises up into the atmosphere. As it rises up into the atmosphere, it eventually cools and condensation starts taking place. After a definite period of time, rainfall occurs.

Thus, in the given image, location 4 shows the low pressure area.
