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 does a barometer do?

• Detect changes in the density in the air

• Measure temperature changes

• Calculate humidity levels

• Track wind speed

What happens to the air the higher you get in the atmosphere?

• It gets warmer because it is closer to the sun

• It gets colder because it is further from the ground

• It remains the same temperature regardless of altitude

• It becomes denser due to increased pressure

Why does warm air rise?

• The particles are less dense and more spread out

• It is lighter than cold air

• It contains more moisture

• It is heated by the ground

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

What would cause a big thunderstorm?

• A greater difference between the temperatures near the ground and up in the atmosphere

• High humidity levels in the air

• A sudden drop in atmospheric pressure

• Strong winds at ground level

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 conduction of electricity

Why can we see clouds?

• Water droplets and crystals reflect light to our eyes

• Clouds are made of solid particles that block light

• Clouds emit their own light like stars

• Clouds are visible due to the color of the sky

Gravity pulls down more on objects with?

• More mass

• Less mass

• Equal mass

• No mass

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
