This is a very large ocean wave caused by an underwater earthquake.
What is a tsunami?
100
This measures the average energy of the particles in the air.
What is a thermometer?
100
This is what forms when two air masses collide.
What is a front?
100
These stream-like movements of water have a large effect on an area's climate.
What are surface currents?
100
Differences in air pressure causes this.
What is wind?
200
This is a sudden violent shaking of the ground.
What is an earthquake?
200
This tool tells which way the wind blows.
What is a wind vane?
200
This type of front brings violent weather.
What is an occluded front?
200
This ocean current brings warm weather to European countries like Norway.
What is the Gulf Stream Ocean Current?
200
As Earth rotates this effect makes the winds turn toward the right.
What is the Coriolis Effect?
300
This is a huge storm that forms on waters of 80 degrees or above.
What is a hurricane?
300
This tool measures changes in air pressure.
What is a barometer?
300
This air mass forms over land at the polar regions.
What is a continental polar air mass?
300
This ocean current located off the coast of Peru that forms when winds blowing off the coast of South America weaken, allowing warm water from the western Pacific Ocean to flow eastward.
What is El Nino?
300
The temperature differences between the equator and poles create these.
What is global convection currents?
400
This is a violent funnel of wind with wind speeds of up to 300 mph.
What is a tornado?
400
This tool measures wind speed.
What is an anemometer?
400
This type of air mass forms over the water near the equator.
What is a maritime tropical?
400
Warm water rises and cold water sinks--just like air because of this property.
What is density?
400
These winds blow away from the poles.
What are the polar easterlies?
500
These two dangers can occur during a hurricane.
What is storm surge and tornadoes?
500
This tool measures relative humidity using a wet bulb and dry bulb thermometer.
What is a pyschrometer?
500
This type of front brings many days of clouds and wet weather.
What is a stationary front?
500
These affect local conditions and a region's climate.
What is large bodies of water and/or ocean currents?
500
Calm areas of falling air.
What are horse latitudes?
