What is density?
How much mass is inside a given volume.
Notes on density
2 objects have the same mass but one is larger than the other. The bigger object’s mass is more spread out so it has lower density Same mass less space =higher density Same mass more space= lower density If you are more dense you will sink If you are less dense you will float
2 objects have the same mass but one is larger than the other. The larger object has higher or lower density?
Lower density
2 objects have the same mass but one is larger than the other. The smaller object has higher or lower density?
Higher density
What are lithospheric plates also known as?
Tectonic plates
What are the three boundary plates?
Convergent, transform, and divergent
Describe the convergent boundary.
- Pushes crust together➡️⬅️
- Forms volcanoes, mountains, earthquake, and deep ocean trench
- Destroys crust
