Is the oceanic crust a thick layer?
Continental plates are thicker and of lower density than oceanic plates. They float like giant rock icebergs deeply embedded in the upper part of the mantle, while oceanic plates form more of a surface skin on the top of the mantle.
What are the tectonic plates float on?
The continental plates float on asthenosphere, molten rock (lava).
What is broken into sections called plates which float on top of the crust?
tectonic plates
Plates of the lithosphere float on Core?
Plates of the lithosphere do not float on the core. They float on the asthenosphere (plastic mantle). Due to convection currents and the earths rotation, plates glide over the asthenosphere. This theory is the theory of Plate Tectonics.
What do plates float on?
Upper mantle
What Plates ride or float on the top of the?
The crustal plates (both continental and oceanic) float on the denser mantle.
What is the difference between a plate and a continent?
A continent is what floats on top of the plate. There are continental and oceanic plates. The continents float on the continental plate and the ocean sits on the oceanic plate. But there are also plates that carry both continents and oceans. The plates are what causes continental drift. So basically plates are what carry the continents and oceans.
How do plates push together?
Both continental and oceanic plates float on the top surface of the mantle, which is divided into convection cells. The movement of these convection cells drag the plates along: where convection causes the mantle material to fall the plates are pushed together and where convection causes the mantle material to rise the plates are pulled apart.
How are the pushed together and pulled apart?
Both continental and oceanic plates float on the top surface of the mantle, which is divided into convection cells. The movement of these convection cells drag the plates along: where convection causes the mantle material to fall the plates are pushed together and where convection causes the mantle material to rise the plates are pulled apart.
Why do some tectonic plates sink while others float?
They all float (on the mantle), some just float lower than others. The main reason is what they're made of; all plates have a high percentage of silica in them, but those with more aluminium than magnesium (continental plates) float higher than those with more magnesium (ocean floor plates) because they're less dense.
Is the oceanic crust a thick layer?
Continental plates are thicker and of lower density than oceanic plates. They float like giant rock icebergs deeply embedded in the upper part of the mantle, while oceanic plates form more of a surface skin on the top of the mantle.
What causes the Continental and oceani plates to move?
The tectonic plates move because of the great amount of liquid rock, or magma that they 'float' on and get pushed by.
Where does crustal plates float?
the plates float on top of the upper mantle
What do the plates on the earth crust float on?
There called tectonic plates, and they do not float on anything.
Tectonic plates float on what?
The tectonic plates float on the lithosphere. This overlies the asthenosphere.
What do the plates on the Earth's crust float on?
There called tectonic plates, and they do not float on anything.
What do the plates that form the earths crust float on?
There called tectonic plates, and they do not float on anything.
