When the water around the equator in the Pacific Ocean are warmer than normal around Christmas time, this causes the weather to be effected all over the globe.
What is La Nina?
100
When the boundary between two air masses stalls?
What is a stationary front?
100
A natural movement of air of any velocity.
What is wind?
100
The amount of water vapor present in the air compared to the amount needed for precipitation.
What is relative humidity?
100
What is the symbol "H" used for on a weather map?
What is a high pressure system?
200
When this event happens, it can cause so much dust to enter the atmosphere that it can block out the Sun's rays for many years. This causes the temperatures to drop. Scientists believe this is what caused the extinction of the dinosaurs.
What is an asteroid impact?
200
When a colder air mass moves toward a warmer air mass.
What is a cold front?
200
The measure of the average amount of motion of particles in the air.
What is temperature?
200
The average weather conditions that occur in a particular region over a long period of time.
What is climate?
200
Lines with triangles or half circles are symbols for these on a weather map.
What are fronts?
300
Because these are made of large amounts of ice, they reflect the Sun's rays, which in turn causes the temperatures above them to be lower.
What are glaciers?
300
When a warm air mass moves toward colder, dense air.
What is a warm front?
300
Refers to the Earth's atmosphere at a certain time and place.
What is weather?
300
The tool used to measure the air pressure.
What is a barometer?
300
The symbol "L" represents what on a weather map?
What is a low pressure system?
400
This happens when the ocean temperatures close to the equator in the Pacific Ocean are warmer than normal around Christmas time. This, in turn, causes the weather to be different than normal around the globe.
What is El Nino?
400
When a cold front moves faster than a warm front, and it catches up to the warm front.
What is an occluded front?
400
A large area of air that has uniform temperature, humidity, and pressure.
What is air masses?
400
Water that falls from the clouds in the form of rain, sleet, hail, or snow.
What is precipitation?
400
Knowing this will help you determine when a front will arrive in a certain place.
What is wind speed?
500
These events that happen on Earth, cause gases and dust to rise up into the air, which blocks out the Sun's rays and lowers the atmospheric temperature.
What are volcanoes?
500
What almost always happens at any type of front?
What is precipitation?
500
The amount of water vapor present in the air.
What is humidity?
500
A boundary between two air masses of different density, moisture, or temperature.
What are fronts?
500
Knowing this will help you know where a front is coming from.
