What 2 reasons explain the uneven distribution of heat across Earth?
1) Earth's tilted axis
2) Earth's spherical shape
Explain why atmosphere pressure is greatest at sea level.
Due to gravity, there is more air pressing down at level than the mountains since you are closer to Earth's surface

Describe the 3 major events that scientists believe led to the formation of our current atmosphere
1)Water vapor condensing into oceans
2) Carbon dioxide dissolving into oceans
3) Algae and plants producing oxygen through photosynthesis
Define and describe the 4 major atmospheric factors
1) Heat energy - describes how hot or cold it is;solar energy from sun
2) Air pressure - the result of weight and density in the air
3) Moisture - water vapor/humidity
4) Winds - movement of air in the sky
