Forces & Patterns
What are the two geological forces that affect landforms on Earth?
1. Constructive forces
2. Destructive forces
What are the large pieces of Earth's crust called?
Tectonic plates
Where are tectonic plates formed?
Mid-ocean ridges
What are the three types of plate boundaries?
You get an additional point if the answer is given with the dance!
1. Convergent
2. Divergent
3. Transform
What is the difference between constructive and destructive forces?
Constructive forces build up new landforms, whereas destructive forces wear down existing landforms.
What are the two types of tectonic plates?
1. Oceanic plate
2. Continental plate
Where are tectonic plates destroyed?
Deep ocean trenches
Which plate boundary interaction causes the biggest earthquakes?
Convergent boundaries
How do we map tectonic plates?
We map the tectonic plates by observing global patterns!
What is the geological process that occurs in the Earth's mantle that moves the tectonic plates called?
Convection currents
What is the geological process called that spreads the plates outward toward the plate boundaries?
Seafloor spreading
Which plate boundary interaction neither creates nor destroys new crust?
If you also answer WHY you get an additional point!
Transform boundaries.
Shear force drives the sliding interaction between the two plates, rather than plates colliding with or separating from one another.
