Add more earth science to this stuff
Pressure… more stuff
Temperature volume, pressure… again• Charles law: temperature and volume– ↑ temperature… ↑ volume– ↓ temperature… ↓ volume
• New notes…• As a gas is warmed, it expands… and rises in
the atmosphere.. Pressure also increases• Cooling a gas compresses it and it sinks in the
atmosphere… pressure also decreases• explain this on the next slides!!!!• yarp
Sea breeze… nice and coldAs warm air moves, it pushes/displaces
the air above it. Add high and low pressure…
Land breeze warms the heart • Add more of the same…
Wait a sec here… didn’t we see this before??? Aw yea!!!!
• What is convection????• Add specific heat capacity of water and land…– Which one is higher temp. during the day???– Which one is higher temp. during the night???
• Tell the WHOLE STORY ON THOSE DIAGRAMS AGAIN!!!!!!!
Convection currents on a planetary scale
Add some rotation make directions curvy…
Oh boy… frames of reference… just like video games… but now the planet is the thing moving… and we are on it.. Show the globe!!!
The earth and the moon…
How they affect each other
Non-note nerd stuff!!!!• Earth to sun = 150 million kilometers• Earth to moon 384 thousand kilometers• Earth orbit around sun = 30,000 m/sec• Earth rotation speed = 45 m/sec• Nerdy…
Note time: Space terms• Orbit = regular repeating path of an object in
space• Satellite = object in orbit… (includes moon)
• To remain in orbit, satellites need to be moving fast enough to balance against the pull of gravity of our planet
• yarp
Escape velocity, Orbital velocity and earth’s gravity
• The moon orbital velocity
• v = 1028 m/sec
Ooohhh… math
• Scientists calculate the correct details to launch a satellite
• Escape velocity• Distance from the
planet• Orbital velocity
Gravities and tides
Spring tide
neap tidehigh tide
Day night winter summer…• What causes the seasons???• What???• WHAT????• Tilt of our planet causes seasons• Show em… got a globe… got a light???• Check out da videos• yarp
Phases of the moon• Aw check
the internet video!!!!
Eclipses…
eclipses
• Solar eclipse: the moon is between the sun and earth casting a shadow
• Lunar eclipse: the earth is between the sun and moon casting a shadow…
• What??? More videos??? Sweetness!!!!• You likey???• Is done… notes a done!!!• yarpness
