Front

What is a warm front?

Back

A warm front is a boundary between a warm air mass and a cooler air mass, where the warm air rises over the cooler air, often leading to precipitation.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth, resulting in clockwise movement in the northern hemisphere and counter-clockwise movement in the southern hemisphere.

Front

What are thermal insulators?

Back

Thermal insulators are materials that do not conduct heat well and are used to reduce the transfer of heat.

Front

What type of weather is associated with low pressure systems?

Back

Low pressure systems are typically associated with rainy or stormy weather.

Front

What does a stationary front indicate?

Back

A stationary front indicates a boundary between two air masses that are not moving, often leading to prolonged periods of cloudy and wet weather.

Front

What is a cold front?

Back

A cold front is a boundary where a cold air mass is replacing a warm air mass, often resulting in thunderstorms and a drop in temperature.

Front

What is a hurricane?

Back

A hurricane is a large, organized system of clouds and thunderstorms with a defined circulation pattern, typically forming over warm ocean waters.

Front

What is the difference between a warm front and a cold front?

Back

A warm front brings warm air over cooler air, leading to gradual temperature increases and precipitation, while a cold front pushes cold air into a warm area, causing abrupt weather changes and storms.

Front

What is the role of high pressure systems in weather?

Back

High pressure systems are associated with clear skies and stable weather conditions, as they inhibit cloud formation.

Front

What is an occluded front?

Back

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