What is the zones places where the seafloor is forced under continents to drift?
Subduction zones are where the seafloor is forced under continental plates.
Which of earth layers are the thickest?
As measured by its thickness from upper boundary to lower boundary in a downward direction, the mantle is the thickest layer of the Earth.
A seafloor plate collides with a continal plate.what will happen?
The oceanic plate (sea-floor plate) is denser than the continental plate, so the oceanic plate will be pulled under the continental plate (subduction) and into the upper mantle, creating an underwater volcano.
The thickness of the earths mantle?
The Earth's mantle is about 2,890 km (or 1,800 mi) thick.
Where do volcanoes create crust?
Definition: Outermost layer of Earth- Plates fit together like a jigsaw puzzle! State: Solid- Lighter crustal plates float on denser mantle Thickness: - Contains: 2types: Oceanic Crust and Continental Crust Oceanic is heavier but thinner than Continental Crust
What is the zones places where the seafloor is forced under continents to drift?
Subduction zones are where the seafloor is forced under continental plates.
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Because its less dense
What is is the thickness of the upper mantle?
In oceanic areas the upper mantle is usually 5-200km thick and on continental areas it is 75-300km deep.
If continental crust were thinner than its average thickness of 40km would it depress the mantle more or less than it does now?
no
What is the thickness of Mantle?
It is 2,900 kilometers
Which of earth layers are the thickest?
As measured by its thickness from upper boundary to lower boundary in a downward direction, the mantle is the thickest layer of the Earth.
Seafloor spreading is caused by what?
Convection currents within earth's mantle are responsible for both continental drift and sea floor spreading. The heat driving these currents comes largely from the decay of long lived isotopes trapped in earth's core and mantle.

What is the place were the seafloor if forced down into the mantle?
mid ocean ridge
What is Place were the seafloor is force down into the mantle?
mid ocean ridge
Thickness of lower mantle?
99,877 km
