Tectonic Plates 1
In this type of boundary, plates are moving towards each other.
convergent plate boundaries
In this type of plate boundary, plates are moving apart
divergent plate boundaries
What is the thinnest part of the earth?
the crust or lithosphere
This type of plate boundary creates seafloor spreading
divergent plate boundary
What is the name of the theory that states the earth's crust is made of large sections moving over the mantle.
Plate Tectonics Theory
Where do tectonic plates interact?
at the boundaries
What specifically lies directly beneath the earth's crust
Asthenosphere (upper mantle)
Evidence of what lies inside the Earth
What are seismic waves, material, and condition of the earth's interior.
What is the most inner layer of the earth
the core
The huge land masses that sit upon tectonic plates.
continents
What is one evidence to support the plate tectonic theory
- the landmasses fit like a jigsaw puzzle
- Fossils
- Volcanoes and Mountain building
Where do convection currents occurs?
the Asthenosphere (Upper mantle)
What causes the plates to move?
convection currents in the mantle
What oozes out of the earth when plates diverge?
magma
The biggest fault in California
the San Andreas Fault
Plate boundary where no volcanic activity is present
What is Transform
Divergent plate boundaries create these features if under water
mid-ocean ridges (also called oceanic spreading ridges) and underwater volcanoes
Plate boundary where plates slide against one another moving in the same direction at different rates or different directions
Transform
When a plate slides under another
subduction
A sudden and sometimes violent shaking of the ground, sometimes causing great destruction.
earthquakes
A continental plate converging with a continental plate creates this
mountains
What do oceanic-to-oceanic convergent plate boundaries create?
deep-ocean trenches, volcanic island arcs, and powerful earthquakes
What are the largest mountains above sea level created by convergent plate boundaries specifically a collision zone?
the Himalayas
The Mid- Atlantic Ridge is a result of what plate boundary
Divergent
What do oceanic to continental convergent plate boundaries create?
What are volcanoes on land and trenches in the ocean also produce seismic activity
