Astronomy
100
Slightly wider at the equator, due to fast rotation
Oblate Spheroid
100
Cloud of Ash and Dust when a composite Volcano erupts.
Ash Cloud
100
Metal Sphere which is lowered on cables to the deep ocean floor
Bathysphere
100
-0.4% - Primary Greenhouse Gas, Essential to life
Water Vapor

Solar System was originally a "Nebula" - cloud of dust and gas, the nebula is pulled to the center by gravity and begins to rotate, results in formation of the sun and planets, Etc.
Nebula Theory
200
Earth spins 24 hours
Rotation
200
Tube where magma rises through a volcano
Conduit
200
Mini-submarine which sinks to the ocean floor and has mobility
Bathyscaphe
200
-.038% - Used by Plants - Man-made greenhouse gas
Carbon Dioxide

"Earth Centered" Most people prior to only a few centuries ago believed earth was the center of solar system
Geocentric
300
Earth traveling around the sun once in a year.
Revolution (Orbit)
300
layer of Earth the volcano sits on
Crust
300
Flat-topped seamounts from erosion of waves (covered up islands)
Guyots
300
Area where Ozone is extremely thin over the South Pole
The Ozone Hole
400
Imaginary line through the poles tilted at 23.5 degrees
Axis
400
Opening where lava erupts onto the surface
Vent
400
Wind drives currents. Currents beginning near the equator move towards the poles. Currents beginning near the poles move towards the equator.
Cause of Surface Currents

Solar System was originally a "Nebula" - cloud of dust and gas, the nebula is pulled to the center by gravity and begins to rotate, results in formation of the Sun and planets, Etc.

Plates are moving away from one another. Example: Seafloor spreading forms mid-Ocean Ridges.
Divergent Boundaries
500
Additional Openings on the sides of a volcano
Side Vent

Deep Ocean currents are driven by changes in water density. Freezing at the poles causes water to become colder and increase in salinity. Water sinks at the poles and rises at the equator.
Cause of Deep Ocean Currents
500
A wave of energy slightly shorter in wavelength than visible light, it is invisible and causes sunburn.
