Weather Review Flashcard

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a warmer object to a cooler one.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the force exerted by the weight of air above a surface. It decreases with altitude.

Front

What is buoyant force?

Back

Buoyant force is the upward-acting force exerted by a fluid on an object submerged in it, allowing the object to float.

Front

How does air temperature change with height on a sunny day?

Back

Air temperatures tend to be cooler at higher altitudes compared to temperatures closer to the ground.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air. It affects weather conditions and comfort levels.

Front

What is a fluid?

Back

A fluid is a substance that has no fixed shape and yields easily to pressure, including liquids and gases.

Front

What is the role of condensation nuclei in weather?

Back

Condensation nuclei are small particles in the air that provide a surface for water vapor to condense into droplets, forming clouds.

Front

What happens to air pressure as altitude increases?

Back

As altitude increases, air pressure decreases because there is less air above to exert force.

Front

What is the relationship between temperature and humidity?

Back

Higher temperatures can hold more moisture, leading to higher humidity levels.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates, condenses, and precipitates back to the earth.
