What causes the seasons on earth?
The tilt of Earth's axis and its orbit around the sun
As ice continues to melt, what happens to albedo?
decreases
As temperature increases, volume _____.
+50 BONUS: What happens to the molecules during this, why?
As temperature increases, volume increases.
BONUS: Molecules spread out when heated, and condense when cooled
Last stage of the star cycle of low mass and high mass stars.

high mass: black hole,neutron star.
Explain how a metamorphic rock is formed..
Heat and Pressure
Which factor most directly influences whether rocks weather more angular or round?
Climate
What forms convection currents?
Warm air rising, cool air sinking.
This is the temperature/point the air has to cool down to in order for the water vapor to condense into a liquid.
Hint: Morning
Dewpoint

Multiple answers
What determines how resistent a rock is to weathering?
Mineral composition
Describe YOUR weight difference at earths equator and it poles.
You weigh more at the poles because you are closer to the center of the earth. (More gravity)

Difference between a lunar and solar eclipse.
A solar eclipse occurs when the Moon blocks the Sun's light, and a lunar eclipse occurs when the Earth blocks the Sun's light from reaching the Moon.
Difference between weathering and erosion.
Weathering is the breakdown of rocks at or near the Earth's surface, while erosion is the movement of those broken-down pieces by agents like water, wind, and ice.
This is the natural fuel formed from the remains of ancient plants and animals.
Fossil fuel
What are the two pieces of proof that the Big Bang happened?
Redshift (doppler effect) and CMB
Name the characteristics of a high pressure and low pressure system (temp, humidity, weather).
High: Cooler temp, lower humidity, better weather. Low: Hotter temp, higher humidity, poor weather.
