What are the 3 major rock types?
Sedimentary, Metamorphic and Igneous
What is the difference between a convergent and divergent boundary?
Convergent: two plates coming together and colliding
Divergent: two plates moving apart from each other
What is the main factor by humans that puts CO2 in the atmosphere?
Deforestation OR Burning of Fossil Fuels
23.5 degrees south of the equator.

What is a dew point?
Temperature when water vapor condenses into rain
What is the name of the process that determines the age of rocks using radioactive isotopes?
Radioactive Dating
What is the name of the geological process that broke apart Pangea?
Continental Drift
What is the Greenhouse Effect?
A natural process where certain gases in the atmosphere trap heat, keeping the Earth's surface warmer than it would be without them
When the moon completely obstructs the sun from the earth.
Solar Eclipse
High Pressure systems rotate ______ and move ______
Clockwise and Outwards
Which set of surface soil conditions on a hillside would result in the most infiltration of rainfall?
1. Gentle slope, saturated soil, no vegetation
2. Gentle slope, unsaturated soil, vegetation
3. Steep slope, saturated soil, vegetation
4. Steep slope, unsaturated soil, no vegetation
2. Gentle slope, unsaturated soil, vegetation
What is a result of a transform boundary?
Earthquakes, cracks in the ground
How does Deforestation impact/affect the carbon cycle?
Burning or chopping down trees reduces the amount that is stored in trees in the Biosphere. The Carbon that was originally stored in the trees floats up into the atmosphere, adding more CO2 into the atmosphere.
What allows stars to combine heavier elements such as iron in their core?
They have more mass or gravity
Air masses are classified based on their ________ and _______
Temperature and Humidity
What atmospheric change cause an abundance of plants to grow during the Devonian Period?
Increase in CO2 in the atmosphere caused by outgases
Convection Currents
How can Carbon cycle from the Atmosphere to the Cryosphere?
Carbon dissolves directly into water or through rainfall, getting it from the Atmosphere to the Hydrosphere. Any water from the Hydrosphere can then get frozen to the formation of ice, ultimately getting it from the Atmosphere to the Cryosphere.
Why do objects appear red?
This means the objects are moving away, which stretches the light and causes it to appear red
What is the Orographic Effect?
Wet air from the windward (wet) side of a mountain rises from prevailing winds, cools at the top of the mountain, and the leeward (dry) side of the mountain experiences heavy rains

1.) Make the river have a steeper gradient
2.) Make the river have a higher discharge (more water)
3.) Make the river straight
4.) Make the river have a rounded bottom
What are the names of the processes that change the earth's surface? List three Constructive or Destructive forces (or both)
Erosion, Deposition and Weathering
List 4 Greenhouse Gases.
