What is the difference between weather and climate?

Back

Weather is short-term atmospheric conditions, while climate is the long-term average of weather patterns in a region.

What causes wind?

Back

Wind is caused by the uneven heating of the Earth's surface, leading to differences in air pressure.

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids and gases), which causes phenomena like wind and ocean currents.

What is a cold front?

Back

A cold front is a boundary between a mass of cold air and a mass of warm air, often bringing precipitation and a drop in temperature.

What is a warm front?

Back

A warm front is a boundary where warm air moves over cold air, typically resulting in gradual temperature increases and light precipitation.

What is a stationary front?

Back

A stationary front occurs when two air masses meet but neither is strong enough to replace the other, often leading to prolonged periods of cloudy weather.

What is an occluded front?

Back

An occluded front forms when a cold front overtakes a warm front, leading to complex weather patterns and often heavy precipitation.

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a given point, influencing weather patterns and wind.

How does temperature affect air pressure?

Back

As temperature increases, air pressure decreases because warm air is less dense than cold air.
