Weather, Climate and Water Cycling Lessons 1-9

Front

What is transpiration?

Back

Transpiration is the process by which water evaporates from a plant's leaves, stem, or flowers.

Front

Which air is denser: warm air or cold air?

Back

Cold air is denser than warm air.

Front

What is conduction in the context of air temperature?

Back

Conduction is the transfer of thermal energy from the ground to the air near the surface, warming the air.

Front

How does the temperature of air just above the ground compare to the temperature at the ground?

Back

Air just above the ground is at a cooler temperature than the air at the ground.

Front

True or False: Warm air holds more water vapor than cold air.

Back

True.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

Define evaporation.

Back

Evaporation is the process by which liquid water turns into water vapor, usually due to heat.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

What role does vegetation play in the water cycle?

Back

Vegetation contributes to the water cycle through transpiration, releasing water vapor into the atmosphere.
