Layers and Tectonic Plates Quiz Flashcards
As you go deeper into the earth what happens to the temperature?
Hotter
Lithosphere
A rigid layer made up of the uppermost part and mantle of the crust.
Divergent Boundary
The boundary between 2 tectonic plates that are moving away from each other.
Tectonic Plate movement per year is measured in…
Centimeters
Asthenosphere is the layer over which…
The lithosphere floats/moves on it
Earthquake
Shaking and vibration at the surface of the earth resulting from underground movement along a fault plane or from volcanic activity.
Tectonic Plates
Sections of the Earths crust that move due to convection currents
What type of fault/boundary is this?
*One plate going under one going over.
Subduction Convergent
What type of fault/boundary is this?
*Two plates moving away from each other and a bump in the middle (mountains)
Divergent Boundary
Continental Crust
The relatively thick part of the Earth’s crust that forms the large landmasses. Lots of silica.
Inner Core
A dense sphere of solid iron and nickel at the center of the earth’s core.
The red highlighted area is the world’s longest mountain range lying under the water in the deep ocean. What is this mountain range/ridge called?
Mid-oceanic ridge
What type of fault/boundary is this?
*Two plates rubbing against each other (going opposite ways but touching)
Transform
Density
Mass per unit volume
All mid-oceanic ridges are called what type of boundary?
Divergent
