6.3 Weather, Climate & Water Cycle (Part 1 study guide)

How is heat transferred through conduction?

• When particles are touching/colliding and transferring their energy

• Through the movement of fluids in a convection current

• By electromagnetic waves traveling through space

• By the transfer of energy through a vacuum

What are cloud condensation nuclei or CCN?

• Small solid particles in the air that water vapor can condense on

• Large droplets of water that fall from clouds

• Gaseous pollutants that affect air quality

• Ice crystals that form in the upper atmosphere

Why can we see clouds?

• They are made of solid particles that absorb light

• Water droplets and crystals reflect light to our eyes

• They emit their own light like stars

• They are transparent and allow light to pass through

What happens to water vapor when its temperature drops below its condensation point?

• It evaporates into gas.

• It condenses into liquid water.

• It freezes into ice.

• It remains as vapor.

What is humidity?

• The amount of water vapor in the air

• The temperature of the air

• The pressure exerted by the air

• The speed of the wind

Gravity pulls down more on objects with?

• More mass

• Less mass

• Equal mass

• No mass

How is heat transferred through radiation?

• When light is absorbed into objects increasing their energy

• Through direct contact between objects

• By the movement of fluids

• Through the transfer of sound waves

What do we call the circular motion of liquids, caused by areas being heated (rising up) and cooled (sinking down)?

• Convection

• Conduction

• Radiation

• Evaporation

What does a barometer do?

• Detect changes in the density in the air

• Measure temperature changes

• Calculate humidity levels

• Track wind speed

What causes condensation?

• When water vapor particles cool down and lose energy

• When water vapor particles gain energy and heat up

• When water vapor particles are compressed by high pressure

• When water vapor particles evaporate into the air
