Hydrosphere/ Atmosphere

Front

What is the hydrosphere?

Back

The hydrosphere is the combined mass of water found on, under, and above the surface of a planet, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding a planet, held in place by gravity, which is essential for life and influences weather and climate.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air, often expressed as a percentage.

Front

What are pollutants?

Back

Pollutants are harmful substances in air, water, or soil that can cause adverse effects on health and the environment.

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 cloud formation and precipitation.

Front

What is a cold front?

Back

A cold front is a boundary where a cold air mass pushes into a warmer air mass, causing the warm air to rise rapidly, often resulting in thunderstorms.

Front

What is a stationary front?

Back

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

Front

What is an occluded front?

Back

An occluded front forms when a cold front overtakes a warm front, lifting the warm air off the ground and often resulting in complex weather patterns.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates from the Earth's surface, condenses in the atmosphere, and precipitates back to the surface.

Front

What is air pressure?

Back

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