8.10A Practice

Front

What causes warm air to rise in the atmosphere?

Back

Warm air is less dense than cool air, so it rises.

Front

What would remove the source of energy that generates convection and wind on Earth?

Back

Blocking all solar radiation.

Front

What stage of the water cycle involves water vapor cooling into water droplets?

Back

Condensation.

Front

What process creates winds in our atmosphere?

Back

Uneven heating of the air in the atmosphere.

Front

What stage of the water cycle involves liquid water rising into the sky as vapor?

Back

Evaporation.

Front

Define convection currents.

Back

Convection currents are the movement of air or liquid caused by the uneven heating of the substance, leading to rising warm air and sinking cool air.

Front

What is the role of the Sun in the water cycle?

Back

The Sun provides energy that drives evaporation, leading to the formation of clouds and precipitation.

Front

Explain the term 'density' in relation to air particles.

Back

Density refers to the mass of air particles in a given volume; less dense air rises while denser air sinks.

Front

What is precipitation in the water cycle?

Back

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

Front

How does vegetation affect local weather patterns?

Back

Vegetation can influence local weather by providing shade, reducing temperature, and increasing humidity through transpiration.
