Atmosphere
By volume, this gas makes up about 78% of Earth's atmosphere.
Nitrogen
What is the name given where two masses of air of two different temperatures meet?
What is a front.
What is the difference between weather and climate?
the current state of the atmosphere- weather
The average weather of a place over a long period of time(30+ years)- climate
What is the main cause of surface ocean currents?
What are global winds / Coriolis Effect?
The transfer of heat energy by collisions between particles in a substance through a solid is called
Conduction
Weather occurs in this layer of the atmosphere
What is the troposphere?
This air mass brings cool, humid weather to the West Coast of the United States.
What is maritime polar?
Why do we have different weather in different seasons of the year?
the Earth is tilted on it's axis and revolves around the sun, causing certain parts of the Earth to receive more or less sunlight at different times of the year
What is the elevation or distance above sea level?
What is altitude?
This is Earth's biggest source of radiation
What is the Sun?
This layer of the atmosphere contains the ozone layer
What is the stratosphere?
A cold air mass overtakes a warm air mass.
What is cold front?
Which direction does the winds bend to in the northern hemisphere ?
They travel to the right
Heat from the sun's energy is transferred in 3 ways, what are these?
What is convection, radiation and conduction.
Rising and cooling currents in a fluid are responsible for this kind of heat transfer
What is convection?
What are the two main jobs of the atmosphere?
Protection- from meteors/UV light
Trapping- of gasses needed for life and heat
when altitude increases, air pressure ______?
What is decreases?
In the Southern hemisphere the water swirls ___________
clockwise
The equatorial and tropical areas are heated more intensely by the sun, why does this happen?
What is earth tilt.
In convection, hot air rises and cold air sinks. What does density have to do with this?
Hot air is less dense, so it rises, and cooler air is more dense so it sinks.
list at least 3 gases that Earth's atmosphere is made up of and their percentage.
78% Nitrogen
21% Oxygen
1% Argon
0.04% Carbon dioxide
Air flows from ______ to ______ pressure.
Imaginary parallel lines in distance from the equator, this is a factor of regional climate
What is latitude?
What are 3 factors that shape climate?
Latitude
Distance from Water
Elevation
Global Winds
Ocean Currents
If a cup of hot cocoa is set on a table, how is the heat transferred by conduction?
The hot cup touches the cooler table and so it transfers the heat by conduction.
