🗑
|
||||
| Mid-ocean ridges | Form at divergent boundaries underwater, new sea floor forms here.
🗑
|
||||
| Subduction zones | Form at convergent boundaries, create ocean trenches, old crust recycled here.

🗑
|
||||
| Cold fronts and storms | Cold air moves under warm air causing warm air to rise.
🗑
|
||||

🗑
|
||||
| Caused by C02 increase, and burning of fossil fuels. | global warming
🗑
|

🗑
|
||||
| How was the moon formed? | after a large collision with another body, the Earth was encircled by pieces of its own mantle and pieces of the large object that collided with it.
🗑
|
||||

🗑
|
||||
| Four terrestrial planets | Mercury, Venus, Earth, Mars
🗑
|
||||
| Four Jovian Planets | Jupiter, Saturn, Neptune, Uranus
🗑
|
||||
| Why is Pluto no longer a planet? | Too small, not gravitationally dominant, other objects would be planets if it was.
🗑
|
||||
| Our Sun | Formed from gas nebula, fusing hydrogen, stable due to equilibrium of outward and inward forces
🗑

🗑
|
||||
| Adult stars | Main-sequence
🗑
|
||||
| Low mass stars versus high mass stars | low mass turn into white dwarfs, high mass turn into supernovae
🗑
|
||||
| Hurricane growth | warm water makes the air above it rise and new air replaces it as it rises.
🗑
|
||||
