The Atmosphere
the third layer of the atmosphere, coldest layer, meteroids burn up here
mesosphere
a measure of the average kinetic energy of particles is
temperature
wind always moves....
from HIGH pressure to LOW pressure
what is an AIR MASS
the area where two fronts meet
FORMS OVER THE OCEAN, HUMID/WET
MARITIME
contains the ozone layer
stratosphere
The sun shining on the Earth is an example of
radiation
This global wind blows between 30 degrees latitude and the equator in both hemispheres
TRADE WINDS
How much water vapor is in the air is known as...
humidity
the measure of the force with which air molecules push on an area or a surface
air pressure
What gases does Earth's atmophere consist of? Be Specific!
78% Nitrogen, 21% Oxygen, 1% other gases
How Does heat move?
FROM HOT TO COLD, FROM HOT TO COLD, FROM HOT TO COLD!!!
The movement of air caused by cool air sinking and moving down the slope of a mountain, this occurs at night
Mountain Breeze
AIR with LOW energy has....
LOW relative humidity and HIGH pressure = This creates nice/CLEAR weather!
holds 80%-90% to all the matter in the atmosphere, this is where the water cycle and weather occurs.
TROPOSPHERE
When altitude INCREASES these TWO things DECREASE
PRESSURE and DENSITY
The sun heats the Earth's surface, then the surface of the Earth heats the air above it.... what is this an example of?
CONDUCTION.... the AIR is heated because it comes into DIRECT CONTACT with the surface of the Earth.
The calm area around the equator, this area has very little pressure and very little wind
DOLDRUMS
Explain what AIR is like on the Earth at the North and South Poles.
POLES-- Air is COLD, more dense, and HIGH pressure
LOW PRESSURE AIR
high energy, high relative humidity, lousy weather
List the 5 layers of the atmophere starting from SPACE and working towards Earth's surface
Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere
What is the difference between HEAT and THERMAL ENERGY?
HEAT: the energy that is transferred between objects of different temperatures (hot to cold)
THERMAL ENERGY: the total kinetic energy of particles
List the 4 local winds we learned about
land breeze
sea breeze
mountian breeze
valley breeze
What kind of weather would be expected if a WARM FRONT came through?
Drizzly rain followed by warm, clear weather
forms when cold air moves under warm air which is less dense and pushes air up (this produces thunderstorms)
cold front
