Solution
-
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.
-
Air pressure, also known as atmospheric pressure, is the force exerted by the weight of the air in the atmosphere of Earth. It is measured with a barometer and the units of measurement are called millibars.
-
When air is heated, it expands and becomes less dense, which means there are fewer air molecules in a given volume. This results in a decrease in air pressure.
-
Winds are related to rising air because they are caused by differences
