Nov. 8 test review of AWESOMENESS Flashcards
What is a seismologist?
A seismologist is someone who studies earthquakes and what they do to the earth (fun)
Why does the Earth’s crust bend and crack?
Because the plates are crashing into eachother
What are convection cells?
Convection cells are the driving force that move the plates
What causes the convection cells?
they are caused by the uneven temperatures inside the Earth
who proposed the idea of continental drift?
Alfred Wegner
What is continental drift?
its when all the continents are slowly drifting close or further away from eachother
What is Pangea?
Pangea is when all the continents were together
Describe four reasons why the theory of Pangea was proposed
- Africa and South Amreica fit together like a jigsaw puzzle. 2. there were fossils of similar plants and animals on each side of the continents. 3. the Appalachian mountains are in newfoundland and lab. and similar ones are in europe
Name atleast 6 of the major plates
Eurasian, N. American, Pacific, African, Australian, Antarctica,
what are the 3 types of tectonic plates movement?
Convergent, Divergent, and Lateral
Convergent land vs water describe the prcess, draw the process, give an example, physical result of the process
two plates collide and the denser one goes into the mantle ex. Juan de Fuca and N. American plate
a physical result could be that volcanoes are formed.
Convergent land vs land describe the process, draw the process, give an example, physical result of the process
two land plates collide and they push up. ex. Himalayan mnts. physical result is that mountains are formed
Divergent describe the process, draw the process, give an example, physical result of the process
Two plates move away from eachother, ex. Mid-Atlantic range. Physical result is land gets pushed up like Iceland.
Lateral describe the process, draw the process, give an example, physical result of the process
Two plates move past each other laterally ex. San andreas fault in California
