A front is the border between one air mass and another. What is likely happen at fronts?
storms
100
What causes liquid to evaporate?
Heat Energy (example: increase in temperature)
100
What might cause flooding during a hurricane?
rain and storm surge
200
tropical storm with wind speeds of 119 km/hr (74mi/hr) or more
hurricane
200
instrument that measures air pressure
barometer
200
When two air masses come together and form a warm front, what kind of weather is likely to occur?
steady rain followed by clear, warm weather
200
At what air temperature would rain fall?
above 0 degrees (above freezing)
200
What is the best time to go to the beach if you want to walk on cool sand?
late afternoon, early evening (around 6pm)
300
process by which a liquid changes into a gas
evaporation
300
process by which a gas changes into a liquid
condensation
300
What would a cold and wet air mass most likely produce?
Snow
300
At what air temperature would snow fall?
0 degrees and below (freezing and below)
300
A breeze that moves from the water to the land.
sea breeze
400
instrument that measures wind speed
anemometer
400
process in which water moves from the surface of Earth to the air and then back again
water cycle
400
Explain what happens with a cold front.
A cooler mass of air moves and pushes against a warm air mass. This may result in thunderstorms and cooler weather.
400
What are 4 forms of precipitation?
rain, sleet, snow, hail
400
the area on the side of a mountain range that gets little or no rain or cloud cover
rain shadow
500
an instrument that measures wind direction
wind vane
500
an instrument that measures rainfall amounts
rain gauge
500
a front that stays in one place for many days because two air masses do not have enough energy to move (you can expect many days of rain or snow)
stationary front
500
Explain the water cycle.
Energy from the sun warms water on Earth's surface. Water evaporates, changing from liquid to water vapor. Water vapor goes into the air. Water vapor cools and turns to liquid water through a process called condensation. Liquid water falls back to Earth in the form of rain, snow, hail, or sleet.
500
Not all precipitation that falls to earth evaporates. What happens to the rest of the water?
1. Some soaks into the soil. 2. Some of the water that soaks into the soil is used by plants. 3. Some of the water moves deeper into the ground until it reaches solid rock; this is ground water. 4. Some of the water is runoff that flows into creeks and streams, that flow into rivers, and then into the ocean.
