The three types of boundaries.
What is convergent, divergent and transform?
What is oceanic crust?
Type of crust that is thicker than the other.
What is continental?
Type of boundary that formed the Himalayan Mountains.
What is a convergent boundary?
Theory Harry Hess proposed.
What is seafloor spreading?
Type of boundary when crust is destroyed.
What is convergent?
Another name for the lithosphere?
What is crust?
Two continental plates colliding causes this to form.
What are mountains? (can be folded or faulted)
Country split by a divergent boundary, specifically the Mid-Atlantic Ridge.
What is Iceland?
The theory that Alfred Wegener proposed that there was once a supercontinent and continents moved over time.
What is coninental drift?
Type of boundary when new crust forms.
What is divergent?
This happens when an oceanic plate and continental plate collide (not what forms).
The ocean plate subducts.
More dense crust that will subduct.
What is oceanic crust?
Famous transform boundary found in the USA.
What is the San Andreas Fault?
Name 2 pieces of evidence for Plate Tectonics.
What are same fossil on different continents, same rock type/age, glacial grooves, puzzle fit of continents, DNA?
Type of boundary when two plates slide horizontally past each other.
What is transform?
This causes plates to move.
What is convection in the mantle?
Choose number that would need earthquake resistant technology the most.
Finding glacier evidence in Africa is proof of this.
What is continental drift (plates moving, continents having been in vastly differnet places compared to now).
Seafloor spreading - tell the age of the crust closest to the boundary and farthest from the boundary.
What is youngest when closest and oldest when farthest away from boundary?
Three types of convergent boundaries.
What are continental-continental, oceanic-oceanic, and oceanic-continental?
Broken parts of lithosphere that carry continents and oceans.
What are plate tectonics?
Landform that forms over a hot spot.
Landform that is formed by oceanic-oceanic convergent boundaries. (name 1)
What is trench, volano, island arc?
Two of these would show that there would be evidence of a plate boundary:
1. presence of earthquakes
2. number of hurricanes
3. the age of crust
4. size of region
What is presence of earthquakes and the age of the crust?
