Layers
Thinnest layer
What is the Crust
The gradual movement of the continents across the Earth's surface through geological time.
What is continental drift
The 4 main layers of the Earth.
What is Crust, Mantle, Outer Core and Inner Core
When tectonic plates rub against each other this happens.
What is earthquake
Refers to the mantle in the region between the asthenosphere and the outer core
What is Mesosphere
Plate tectonics describes movements mainly in which layer(s) of the Earth
What is Crust and/or Upper Mantle
The thin part of the Earth's crust located under the oceans
What is Oceanic Crust
Mesosphere sits above this layer
What is Core or Outer Core
A rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
What is Volcano
The rigid outer part of the earth, consisting of the crust and upper mantle.
What is Lithosphere
Layer that has the greatest pressure, density and temperature
What is Inner Core
A rocky material that makes up the thickest part of earth's crust not located under the ocean.
What is Continental Crust
Layer that is about 70% of Earths Mass
What is Mantle
When one plate moves up or down, it displaces water, and this displaced water becomes this
What is tsunami
the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur
What is Asthenosphere
Thickest layerS of the Earth
What is Upper Mantle, Middle Mantle and Lower Mantle
The transfer of thermal energy inside the Earth and is the driving force for plate tectonics
What is Convection Currents
This layer is responsible for the magnetic field.
What is core
Region of the Earth’s crust where tectonic plates meet.
What is subduction zone
Scientist that proposed a theory that the continents had once been joined, and over time had drifted apart. This was the Continental Drift Theory.
Who is Alfred Wegener
The order of the layers of the Earth's surface from lowest to highest temperature.
What is Crust, Mantle, Outer Core, Inner Core
Is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere.
What is tectonic plates
This layers includes lithosphere, asthenosphere and mesosphere.
What is Mantle
This causes oceanic features such as trenches, volcanic islands and mid-ocean ridges
What is plates converge, one plate may move under the other
The formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.
What is seafloor spreading
