What type of front occurs when warm air rises over cold air?

Warm Front

100

What tool is used to measure temperature?

Thermometer

100

What are the three states of matter?

Solid, liquid, gas

100

What is a chemical change?

A chemical change is a process that transforms one substance into another, creating new materials.

100

What process in the water cycle involves water turning into vapor?

Evaporation

200

When does a cold front occur? 

A cold front occurs when cold air moves in and replaces warm air.

200

What instrument measures wind speed?

Anemometer

200

How does heating a solid change its state?

Heating a solid can cause it to melt and change into a liquid.

200

Give an example of a chemical change in everyday life.

An example of a chemical change is burning wood, which produces ash and smoke.

(Other answers may be accepted at the teacher's discretion).

What is precipitation?

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

300

How do occluded fronts affect weather conditions?

Occluded fronts can lead to changes in temperature and prolonged precipitation.

300

How does a barometer help predict weather changes?

A barometer measures atmospheric pressure and helps predict weather changes; falling pressure often indicates storms.

300

Give an example of a physical change in matter.

An example of a physical change is melting ice, tearing paper, cutting an apple, etc.

300

How can you tell if a physical change has occurred?

A physical change can be observed without changing the substance's chemical identity (e.g., breaking a glass).

300

How does the sun's energy impact the water cycle?

The sun's energy heats water, causing it to evaporate and drive the water cycle.

400

Name two types of fronts that can cause precipitation.

Cold fronts and warm fronts can cause precipitation.

400

Explain how a rain gauge is used in weather observation.

A rain gauge collects and measures the amount of precipitation over a period of time.

400

What can happen to materials when they are cooled?

When materials are cooled, they can become more solid or contract in size (get smaller.)

400

How does heating lead to changes in materials?

Heating materials can lead to melting (physical change) or chemical reactions (chemical change).

400

Explain transpiration in plants.

Transpiration is the process by which plants release water vapor into the air through their leaves.

500

What type of weather does a warm front usually bring?

A warm front can lead to a gradual increase in temperature and often brings light rain or drizzle.

500

What is the purpose of a weather satellite?

Weather satellites monitor weather patterns and collect data on atmospheric conditions.

500

Explain how energy affects the properties of materials.

Energy can affect the properties of materials by changing their states (e.g., solid to liquid) or altering their temperature.

500

Summarize the main differences between physical and chemical changes.

Physical changes alter the form of a substance but not its identity, while chemical changes create new substances.

500

Summarize how runoff contributes to the water cycle.

Runoff is water that flows over the ground and returns to rivers, lakes, and oceans, completing the water cycle.
