Mass wasting
What is a one important role in mass wasting
water, oversteepened slopes, vegetation ,earthquakes.
he Earth's outermost layer, consisting of the crust and the very top of the mantle, is broken into these large slabs.
Tectonic Plates
what are the layers called
core, the mantle, and this outermost layer.
This hazard is a vibration deep within the Earth or at its surface, often caused by tectonic plate movement.
Earthquake
what is mass wasting.
the down hill movement of earth material caused by gravity.
his is the name of the ancient "supercontinent" where all of Earth's landmasses were once joined together.
Pangea?
This is the thickest layer of the Earth, located between the crust and the core.
Mantle?
what causes mass wasting
gravity pulling soil and rocks downhill
ectonic plates float and move on top of this soft, semi-fluid layer of the mantle.
Asthenosphere?
These large pieces of the Earth's lithosphere move slowly on the surface, causing earthquakes and forming mountains.
Tectonic Plates
A creep is
the slow steady downward movement of slope-forming soil or rock
This is the scientific theory that describes how the Earth's plates move and shape the planet's surface.
Plate Tectonics?
The process where one tectonic plate sinks below another into the mantle.
Subduction?
A rock fall is
the fastest and most vertical type of mass wasting
Most tectonic plates move at a very slow speed, roughly the same rate that this part of your body grows.
This specific part of the core is liquid and responsible for creating Earth's magnetic field.
Outer Core?
