Global Weather Patterns Review

Front

What is light rain?

Back

Light rain refers to precipitation that falls in small amounts, typically less than 2.5 mm per hour, and is often characterized by gentle, steady drops.

Front

What are jet streams?

Back

Jet streams are fast flowing, narrow air currents found in the atmosphere, typically at altitudes of 6 to 12 km, that influence weather patterns.

Front

What happens to air at the Equator if the Earth did not rotate?

Back

If the Earth did not rotate, air at the Equator would rise and move toward the poles due to the heating from the sun.

Front

In which direction does weather generally move?

Back

Weather generally moves from West to East in the mid-latitudes due to the prevailing westerly winds.

Front

What is the density of cold air compared to warm air?

Back

Cold air is more dense than warm air, which causes it to sink.

Front

What is high pressure in weather terms?

Back

High pressure refers to an area where the atmospheric pressure is greater than that of surrounding areas, often leading to clear skies and calm weather.

Front

What is low pressure in weather terms?

Back

Low pressure refers to an area where the atmospheric pressure is lower than that of surrounding areas, often associated with cloudy skies and precipitation.

Front

What is the role of the sun in weather patterns?

Back

The sun provides energy that heats the Earth's surface, driving wind and weather patterns through convection.

Front

What are the main components of weather?

Back

The main components of weather include temperature, humidity, precipitation, wind speed, and atmospheric pressure.

Front

What is a weather front?

Back

A weather front is a boundary separating two masses of air of different densities, leading to changes in weather conditions.
