What is a cold front?

Back

A cold front is a boundary between a cold air mass and a warm air mass, where the cold air pushes under the warm air, often leading to precipitation.

What is the main reason temperatures drop at night?

Back

The temperature depends on energy from the sun; at night, there is no sunlight to warm the Earth's surface.

Front

What causes wind?

Back

Wind is caused by differences in air temperature and pressure, which create movement of air from high-pressure areas to low-pressure areas.

Front

What type of pressure is associated with clear weather?

Back

High pressure is associated with clear weather.

Front

What type of weather is typically associated with low pressure?

Back

Low pressure is typically associated with rainy weather.

Front

What is a high pressure system?

Back

A high pressure system is an area where the atmospheric pressure is higher than the surrounding areas, often leading to clear skies and calm weather.

Front

What is a low pressure system?

Back

A low pressure system is an area where the atmospheric pressure is lower than the surrounding areas, often leading to cloudy and rainy weather.

Front

What is a warm front?

Back

A warm front is a boundary where a warm air mass replaces a cold air mass, often resulting in gradual temperature increases and precipitation.

Front

What is the role of the sun in weather?

Back

The sun provides energy that heats the Earth's surface, influencing temperature, wind patterns, and weather systems.

Front

How do clouds form?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.
