Dry air is
more dense and the pressure is higher
A river of water that flows in a definite path in the oceoocean is an
ocean current
Remember the equator is the hottest place. water leaving the equator will then be a
warm current, warm water
Air pressure is
a measure of the force of the air pressing down on the Earth's surface
Mountain ranges act as barriers to prevailing winds. On one side it snows alot. On the side where the winds are blocked
the air is forced up and there is no moisture to fall
A wind that blows most often from one direction than any other
is called a prevailing wind
The polar regions are from 90 to 60 latitude. They include Antartica, Greenland and Alaska. In this area you will find
the coldest average temperature where there is little or no summer and very little precipitation. cold and dry
The higher the elevation
the lower the temperature. It can be raining at the bottom of a mountain and snowing at the top. The air is colder the higher you guy. Wear shorts on the bottom and a coat on the top!!
The tropical clomate zone is at 30 latitude. It is at the equator. Here the
tempetature is high, the humidity is high, and the rainfall is heavy.
Temperate climates are located at 30 to 60 latitude. There are in the middle between the equator and the poles. This includes most of Earth and most of the US. In this area
temperature vaires greatly. Far from the equator it sonws often closer to the equator it rains more.
The greenhouse effect is due largely to
carbon dioxide,
We need to quit putting it in the air. The world is heating up to much!! It is like we have too many blankets.
The surace temperature of water will effect the temperature of
the air above it
The name of a wind is determined by
the direction from which the wind comes
Air pressure density is affected by
Water Vapor
The ozone layer protects the Earth by absorbing
ultraviolet rays. It is sort of like sun block on your skin. Too much sun isn't good for us, nor for our planet!! We need to protect the ozone layer by not polluting. If we don't we just might get burned.
What determines the air temperature of a region?
The angle at which the sun's rays strike the Earth determines the air temperature of a region.
A cloud forms when moistue in the air
condenses or connects to small particles in the air. It gets heavier then and so it falls.
Heat Energy is
radiant energy from the sun
The process in which carbon dioxide and other gases in the atmosphere absorb infrared radiation from the sun forming a heat blanket around the earth is
the greenhouse effect--The greenhouse effect is like a blanket because it helps trap heat and warms!!
Heat energy is measured with a
The atmosphere factors that interact (mix) to cause weather are
Heat Energy
Air Pressure
Temperature is effected by
Movement of air from an area of high pressure to an area of low pressure due to unequal heating is
Altitude is
The distance you are above sea level
The instrument used to measure air pressure is
a barometer
When the temperature is high
the air heats up and is less dense there is less pressure
When the temperature is low
the air is cooler, more dense and the pressure is higher
When the altitude goes up
the air is less dense and there is less air pressure
When the altitude is down the air is
more dense and there is more air pressure
Mooist air is
less dense and the pressure is lower
Remember it is cold at the north and south poles. If you move away from where it is hottest, the equator, to the north or south pool the temperatures will start to get
cooler of course!! The closer to the equator the warmer you will be and therefore the further away the cooler you will be. It is really simple if you remember you are closer to the sun and its rays at the equator. Move away and it gets colder the futher you move. It is sorta like moving away from a heater.
The sun's rays are most direct and therefore it is hottest at the
Remember the poles are the coldest place so water currents leaving the poles will be
An anemometer
measures wind speed
A weather vane tells you
the direction a wind is coming from
Precipitation is effected by prevailing winds because
of the amount of moisture in the air, the more moisture in the air the more rainfall or snow you can have
The daily conditions of the atmosphere is called
