What is wind?
Wind is the movement of the air.
100
What are the two main wind patterns?
Global winds and local winds
100
Why did the blown up baloon weigh more than the baloon that wasn't blown up?
Air has mass so the blown up baloon had more air.
100
What is used to measure air pressure?
A barometer.
100
High pressure fronts are typically warmer or colder?
Colder.
200
How does wind blow?
Wind blows from high pressure to low pressure.
200
What is the difference between local winds and global winds?
Local winds are winds that cover just a small portion of land. Global winds are winds that cover the entire globe.
200
Why did the can implode when the cap was placed on?
The air pressure was too intense.
200
What are the lines on a weather map called that represent change in air pressure?
Isobars.
200
Does air rise or sink in a high pressure system?
Air sinks in a high pressure system.
300
Where are pressure belts located?
Every 30 degrees North latitude.
300
What do the arrows on a pressure gradient represent?
The arrows represent how windy a certain place is.
300
Why did the land heat up much faster than the water in the uneven heating of the Earth lab?
Because the radiation from the sun only affects the surface of the land. The radiation from the sun heats all the way down, so it takes much longer to heat.
300
As altitude increases, air pressure __________.
Decreases.
300
What causes the different air pressures?
The different air pressures are caused by air colliding in the upper atmosphere.
400
Why does air move?
Due to uneven heating in the Earth.
400
What is a land breeze?
A land breeze is when the air on the land rises. The air is replaced from the sea. These winds are usually pretty strong.
400
What does the lamp represent in the uneven heating of land and water lab?
The sun, and the sun's radiation
400
The more windy it is, the bigger the arrows are on a __________ ___________.
Pressure Gradient
400
Is warm air more or less dense than cold air?
Less dense.
500
What is a sea breeze?
A sea breeze is when the land is cooler than the ocean. So the air over the water starts to rise and it is replaced by the air from the land.
500
If you are a flying a plane in the north hemisphere and you can not turn, in which direction would you point yourself? Choices: A: To the right a little bit B: To the left a little bit C: straight where you want to go.
B because the Coriolis effect makes wind go a little to the right in the Northern hemisphere.
500
Imagine you are on the beach. It is 9 o'clock and the sun set at 5 o'clock. Which would be most likely warmer and why: the beach or the ocean?
The ocean would likely be warmer because land cools down very quickly and water does not.
500
Why would a baloon move forwards if you swat at the air in front of it?
Because air moves from high pressure to low. So when you swat the air from in front of a baloon, the low air pressure is where you just displaced the air.
500
Why would a low pressure system make clouds and precipitation?
Because the warm air is rising, so it forms clouds.
