Clouds & Water Cycle
This process occurs when water vapor cools and forms tiny droplets that gather together.
What is condensation?
On a weather map, the letter “L” indicates…
What is low pressure?
The amount of water vapor in the air.
What is humidity?
The spinning of the Earth on its axis explains
What is day & night?
“Winters are colder in Dallas than in Los Angeles.” This describes…
What is climate?
This is what the Sun does to water to start the process of cloud formation.
What is heating water into water vapor (evaporation)?
This type of front forms when a cold air mass pushes under a warm air mass.
What is a cold front?
This instrument measures the pressure of the air.
What is a barometer?
What does the Earth experience seasons?
The Northern Hemisphere tilts toward or away from the Sun as Earth revolves around it.
“It snowed 8 inches overnight in New York.” This describes…
Weather
During a storm, humidity increases. Explain why this leads to cloud and storm formation.
When humidity increases, more water vapor is in the air, which rises, cools, and condenses into clouds.
Why are storms more likely to form near low-pressure systems on a weather map?
Because air rises in low-pressure systems, cools, and condenses to form clouds and precipitation.
If humidity is very high and air pressure begins to drop, what type of weather is most likely to occur and why?
Stormy weather
The difference between rotation and revolution
Rotation is Earth spinning on its axis; revolution is Earth orbiting the Sun.
A graph shows cities near the equator with little temperature change and opposite seasons in Northern and Southern Hemispheres. This pattern is caused by…
What is Earth’s tilt and revolution around the Sun?
This step in the water cycle releases water from plants into the air.
What is transpiration?
In a high-pressure system, you would expect…
Dry air and clear skies.
A decrease in air pressure can cause storms. Explain why.
When air pressure decreases, air rises and water vapor condenses to form clouds, which can lead to storms.
If the Northern Hemisphere is tilted away from the Sun, it is experiencing which season?
What is winter?
