Water changes from a liquid to a gas in this process
What is evaporation?
100
True or false?
Air molecules move differently at different temperatures.
TRUE
100
Air with similar temperature and humidity.
What is an air mass?
100
True or False?
Clouds are made of water vapor.
FALSE
100
What is weather?
Weather is the daily condition of the atmosphere, such as sunny, cloudy, rainy, or snowy.
200
The water cycle depends on _______ to provide it energy
What is the sun?
200
How are temperature and pressure related?
Warm air has LOW air pressure.
Cold air has HIGH air pressure.
200
Kind of weather you have with a high pressure air mass.
What is clear and dry?
200
Describe how clouds form.
Water vapor rises and condenses, turning into tiny drops of liquid water (condensation).
200
True or False?
All water on Earth is the same water as always, just recycled.
TRUE
300
The process of water molecules in the air is changed into liquid water.
What is condensation?
300
Cold air is ______ dense so it ______.
Warm air is ______ dense so it ______.
Cold air is MORE dense so it SINKS.
Warm air is LESS dense so it RISES.
300
Weather with a low pressure air mass.
What is cloudy, windy and rainy?
300
Name this cloud
Stratus
300
Where does the majority of the water that has been evaporated into the atmosphere come from?
Oceans
400
Which TWO main processes in the water cycle are influenced by gravity?
What is precipitation and runoff?
400
Air ALWAYS moves from ______ pressure to ______ pressure.
high to low
400
Changes in weather is caused by two ________ colliding.
fronts
400
Name this high-level cloud
Cirrus
400
What creates wind?
Differences in pressure. Air always moves from high to low pressure.
500
How does transpiration help move water in the water cycle?
Plants release water vapor into the atmosphere.
500
What creates areas of high pressure and areas of low pressure on Earth?
Different locations receive different amounts of solar energy (energy from the sun).
500
Briefly describe a cold front, warm front, and stationary front.
Cold Front - a cold air mass pushes the warm air which is forced up.
Warm Front - a warm air mass overtakes a cold air mass.
Stationary Front - two air masses of different temperatures do not move.
500
Name this common cloud:
cumulus
500
Explain why thunderstorms are most likely to form on a hot day.
Warm, humid air rises quickly and then condenses into rain clouds.
