Weather
An air mass has the same temperature and humidity throughout it.
Climate is weather over a long period of time in a certain place.-NC
Weather is the air mass of a particular time or place.-HZ
MS
Temperature
Hot air has low pressure and rises. Cold air has high pressure and sinks.
-ELS
Conduction is the transfer of heat between two
objects that are touching. Convection is the way
heat moves through gases and liquids. Radiation
is the way heat moves through empty space. -ELS
Cold air is more dense than warm air. That’s why
warm air
rises and cool air sinks. -AAM
Temperature: The measurement of the speed molecules are moving. MH
Dew point: The temperature at which dew forms. JI
Layers of the atmosphere
The layers of the atmosphere are the: Troposphere,
Stratosphere, Mesosphere, Thermosphere, Exosphere and
Ionosphere. ABS and MS
The first layer of the atmosphere is the Troposphere. It is also
the layer we have planes and precipitation. The second layer is
the Stratosphere. This is where the ozone layer and the jet
streams are. The the third layer is the Mesosphere. This is the
coldest layer. It is also the layer where meteors are. The
Thermosphere is the fourth layer of the atmosphere. The
Ionosphere is the first portion of the Thermosphere. The
Aurora Borealis occurs here. This is also where the radio
waves bounce back to earth and the atoms get charged. -HZ
The layers of the atmosphere in order of closest to earth to farthest from earth are: The troposphere, the
stratosphere, the mesosphere, the thermosphere, the ionosphere (the first portion of the thermosphere), and
the exosphere. Weather occurs in the troposphere and airplanes fly in that layer. The ozone layer is in the
stratosphere. -ELS
The 4 types of fronts are: Warm and Wet, Warm and Dry, Cold and Wet, Cold and Dry. -AQ
The coriolis effect happens because the earth rotates while the wind is blowing. JI
A sea breeze is coming from the sea to the land and happens during the day.-NC
An air mass has the same temperature and humidity throughout it. MS
Hot air has low pressure while cold air has higher pressure JW.
Between high pressure and low pressure is wind -AM
Mountain Rain Shadow
The side where the wind comes up, the mountain it's
wet and the side that the air goes down, the
mountain will be dry.
The mountain rain shadow effect happens when an
air mass rises up the side of a mountain. It is colder
up at the top of the mountain, so it condenses to a
cloud. The cold air cannot hold as much moisture
and it lets it go, causing rain. As it goes back down
the other side of the mountain, it warms up, but it has
lost it moisture so it is dry. The side of the mountain
which got the rain is lush and green, while the side
which got the dry, warm air is like a desert. JI
The change of gas to liquid is condensation. JC
When condensation forms on the outside of a cold bottle, the water came from the moisture in the humid air
when it stuck to the bottle it cooled down to make it visible on the bottle. CF
Pressure: The force of the atmosphere pushing down. MH
States of Matter
Freezing/solidification is the change from liquid to
solid. -AAM
Evaporation is liquid to
gas.NC
Melting is solid to liquid.
MS
Solids- the molecules say
close together and then
the liquid-the molecules
are close together but not
as close as the solid.
Gas-the molecules in a gas feather apart. KO
Sunlight moves through empty space to our planet using radiation. JI
The change of gas to liquid is condensation. JC
The Change from solid to liquid is melting.JW
The change from liquid to gas is evaporation. BP
The change from liquid to solid is freezing/solidification. AQ
Cold fronts are when a cold air mass runs into a warm air mass and makes the warm air mass go up quickly.
Cold fronts cause violent weather like thunderstorms. Warm fronts are when a warm air mass hits into a cold
air mass which causes snow or gentle rain. -AAM
Solid keeps shape, particles vibrates, hard. Liquid takes the shape of the container, fluid, particles move inside
surface. Gas fluid, fills the space it's in particles move in straight lines in surface until they hit something. AW
All of the water on earth's surface is called surface -runoff. JC
Deposition is the transition from a gas to a solid. AQ
Sublimation is the change from a solid to a gas. JC
If the dew point and the temperature are close together on the chart it
means that the air is humid outside. If the two are more far apart, then
the air is drier. MBA
The Water Cycle
The Water Cycle is driven by the sun
and gravity. AW
The hydrologic cycle is driven by the
sun and gravity-KO
Evaporation from plants is known as
transpiration. NN
An air mass is a huge body of air that
stays together as it moves. It has about
the same temperature and humidity all
through it.-HZ
The Water cycle is the continuous movement of water on, above, and below the surface of the earth.AC
Mountains can create strong winds. Warm air rises up mtn. (Day) cool air sinks down mtn. (Night) This is called
mountain winds.AC
Sea breeze is when the wind blows from the sea to
land only during the day when the sun is out TJ
Land breeze is when the wind blows from the land to the
sea during the night TJ
Wind
Winds are named after the direction that they came from. AQ
Some flowers use wind to pollinate, and some animals like birds use wind to help them fly. Warm air rises, so
birds may fly around in a circle around warm air to get a boost up. AQ
Wind is the transfer of air from high pressure to low pressure. AQ
Wind chill is the cooling effect of the wind and air combined. The higher the speed of the wind the colder it
gets.
0 kelvin equals absolute zero.
Jet Stream: air currents that circle the earth in a westerly direction.
Fronts will happen when one air mass runs into another air mass. The front is named after which front runs into
the other one. AQ
The Jet Stream is winds that are flowing from the west coast to the east coast. It
is harder for an airplane to fly to the west coast because the jet stream is going
against it. MBA
A land breeze happens during the night and it blows towards the sea.JC
The weather that follows a cold front is clear skies and cold temperatures. The
weather that follows a warm front is humid air and warm temperatures. MB
