Why does low air pressure usually indicate stormy weather?
Low air pressure makes it harder for clouds to form.
The air particles are packed together, making it easier for condensation to occur.
The air particles are spread out, allowing evaporation to easily occur.
The packed air particles move faster, causing storms to easily occur.

Why is the weather in low-pressures areas usually cloudy and stormy? ... Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation.

Explanation:

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
