Convergent, Divergent, Transform Boundaries
What are the three types of boundaries?
100

Rigid layer of Earth's surface below the lithosphere. Flows like toothpaste. Plates of the lithosphere float on it.

What is the asthenosphere?

100
Volcanic Eruptions, Earthquakes, Tsunamis
What natural disasters are caused by plate tectonics?
100

Subduction Zones

What convergent oceanic- continental formed?

100

That continents have moved slowly to their current locations. Presence of fossils, rocks, and mountains on different continents help support.

What is Continental Drift Theory?

200
Convergent Boundary
What type of boundary is it when crust destroyed?
200
Crust
What is another name for lithosphere?
200
Two continental plates colliding
What causes fold mountains?
200

Mid- Atlantic Ridge, Great Rift Valley in Africa

Where can divergent boundaries be found?

200

He proposed seafloor spreading the process in which new ocean floor is created at a divergent boundary.

Who is Henry Hess?

300
Divergent Boundary
What type of boundary is it when new crust forms?
300
When an oceanic plate and continental plate collide.
What causes subduction to occur?
300
When faults slip and rise quickly
What forms block mountains?
300

San Andreas Fault, California

Where can transform boundaries be found? (HINT: in the USA)

300

Earth's upper crust and upper mantle broken into sections that are in constant, slow motion driven by movement in the mantle

What is Plate Tectonics?

400
Transform Boundary
What type of boundary is it when two plates slide past each other?
400

Convection Currents

What causes plates to move?

400
Fold, Block, and Volcanic Mountains
What are two of the three mountains formed by plate tectonics?
400

Himalayan Mountain Range (Himalayas)

What mountain range is formed by continental-continental boundaries?

400

Alfred Wegener

What guy was not trusted with his idea of movement of plate tectonics?

500
continental-continental, oceanic-oceanic, and oceanic-continental
What are the three types of convergent boundaries?
500
Broken parts of lithosphere that carry continents and oceans
What are plate tectonics?
500
Fossil Fuels, Ore, Fertile Soil, Minerals
What is one natural resource caused by plate tectonics?
500
Marina's Trench
What trench is formed by oceanic-oceanic boundaries?
500

new ocean floor is created as molten material from the earth's mantle rises in margins between plates or ridges and spreads out

What is seafloor spreading?
