Weather, Climate & Water Cycling CFA

Front

What is an air mass?

Back

An air mass is a large body of air that has uniform temperature and humidity characteristics. It can influence the weather in the regions it moves over.

Front

What weather conditions does a cool and dry air mass bring?

Back

A cool and dry air mass typically brings clear skies and lower humidity, leading to fair weather.

Front

What causes a sea breeze?

Back

A sea breeze is caused by a temperature difference between the land and the water, where cooler air from the sea moves towards the warmer land.

Front

What is the role of temperature in precipitation?

Back

Temperature determines whether precipitation falls as rain or snow; warmer temperatures lead to rain, while colder temperatures lead to snow.

Front

What are prevailing winds?

Back

Prevailing winds are winds that blow predominantly from a single general direction over a particular point on the Earth's surface.

Front

How do air masses move?

Back

Air masses move due to the influence of prevailing winds and upper air currents, which can change weather patterns.

Front

What is the difference between weather and climate?

Back

Weather refers to the short-term atmospheric conditions in a specific area, while climate is the long-term average of weather patterns over a significant period.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air, which can affect weather conditions and comfort levels.

Front

What is a cold front?

Back

A cold front is the leading edge of a cooler mass of air, which can cause sudden changes in weather, including storms.

Front

What is a warm front?

Back

A warm front is the leading edge of a warmer mass of air, which typically brings gradual changes in weather, such as light rain.
