100

What is the main source of energy for the Earth?

The Sun.

100

What happens to warm air?

Warm air rises because it is less dense.

100

What is a key factor in air rising?

Warmth and lower density.

100

What is evaporation?

The process of liquid water turning into water vapor.

100

when thermal energy is transferred via particle collisions

Conduction

200

How does the Sun's radiation warm the ground?

The Sun's radiation heats the ground directly.

200

Why does warm air rise?

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

200

What happens to cooler air?

Cooler air sinks because it is denser.

200

How does humidity affect weather?

High humidity can lead to cloud formation and precipitation.

200

Transfer of heat through empty space

Radiation

300

What is thermal energy?

Thermal energy produced when a rise in temperature causes atoms and molecules to move faster and collide with each other.

300

What is conduction?

Conduction is the transfer of heat through direct contact.

300
List 3 reasons why air moves.
Different temperature, pressure, gravity
300

How does water vapor affect the air?

Water vapor increases humidity and can change air pressure.

300

the relationship between the amount of matter in a sample and its volume

density

400

How does the Sun's energy affect water?

The Sun heats water, causing it to evaporate.

400

What does less dense air do?

Less dense air rises, creating upward air movement.

400

Why do air parcels push up against gravity?

As air rises, it moves against the pull of gravity because the surrounding cooler, heavier air pushes it upward.

400

What role does evaporation play in humidity?

Evaporation adds water vapor to the air, increasing humidity levels.

400

Any type of solid particle that water vapor sticks to as it cools down. 

Cloud Condensation Nuclei (CCN)

500

Describe the process of energy transfer from the Sun to the Earth.

The Sun radiates energy, warming the Earth's surface, which then warms the air above it through conduction.

500

Explain how air density affects weather patterns.

The higher the temperatures the less dense the air. The changes in our temperatures from hot to cold within the air in our atmosphere causes winds which then help create high and low pressure areas. So, changes in air density help create winds, clouds, and different types of weather, like sunny skies or rainy days!

500

What weather conditions are needed for a storm?

Warm air, low air pressure, high humidity

500

How does high humidity help make thunderstorms stronger?

High humidity can also fuel strong storms like thunderstorms. The moisture in the air provides energy for the storm, making it more intense.
