because of the uneven heating and cooling of the earth's surface.
What is Why do Low and High pressure systems occur
100
cold air mass moves under a warm air mass causing the warm air to rise.cold fronts bring heavy rains thunderstorm and some times snow. It brings cooler weather
What is Cold Front
100
measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is.
What is A Thermometer
100
1. winds that come from the polar areas.
2.(H) air
(L) molecules
1. What is What are easterly winds
2. Why do winds blow
200
1. usually brings dry, clear weather. (H)
2. a scientist who studies and predicts weather
1. What is high air pressure
2. What is a meteorologist
200
wind breeze that blow from the sea into dry land.
What is Sea Breeze
200
a warm air mass moves over a cold air mass slowly replaces the cold air mass and brings rainy drizzly weather often followed by warm clear weather.
What is Warm Front
200
measures the amount of rain that has fallen over a specific time period.
What is A Rain Gauge
200
1. westerly winds
2. warm air rises and cooler air sink and takes its place this forms a circular motion.
1. What is What wind zone is the U.S. in
2. Convection Cell
300
usually brings cloud, storms and rain. (L)
What is Low air pressure
300
Wind that blows from land to sea at night
What is Land Breeze
300
the area where two air masses meet
What is Front
300
is an instrument that determines the direction from which the wind is blowing.
What is A Wind Vane
300
1. from west to east because of the jet stream.
2. altitude temperture and water vapor
1.What is What direction does weather usually travel across North Carolina and why
2.What affects air pressure
400
water evaporates from earth and rises. When the air cools the water vapor condenses. They from water droplets. Theses droplets clump together around dust particles forming clouds.
What is how do clouds form
400
the curving of wind patterns caused by the earths rotation northern curves right and southern curves left
What is Coriolis Effect
400
as two air masses move toward each other, warm air between them is pushed upward. This brings cool temperatures and plenty of rain and snow.
What is Occluded Front
400
measures air jpressure. It tells you whether or not the pressure is rising or falling A siring barometer means sunny and dry conditions while a falling barometer means stormy and wet conditions. An Italian scientist named Torricelli built the first barometer in 1643
What is A Barometer
400
you are!!!
What is Who's awesome
500
cold & warm fronts bring rain. So do occluded and stationary fronts, when two fronts meet a change in weather is on its way.
What is When two fronts meet
500
the heating of the air above the equator moves north and south towards the poles where is coos and kinks this sets a belt of winds in motion around earth
What is How are global trade winds produced?
500
when a warm air mass and cold air mass meet but neither of them more this brings many days of overcast rainy weather.
What is Stationary Front
500
measures wind speed. The cups catch the wind, turning a dial attached to the instrument. The dial shows the wind speed
What is An Anemometer
500
because of the uneven heating and cooling of land and water on the earth's surface.
