Can a molten liquid have the strength to push giants slabs of earths crust?
Magma itself does not force the plates to move. Plate movement is caused by convection currents in the mantle because of intense heat from the Earth's core.
What is the soft layer of the mantle where tectonic plates move?
asthenosphere
Which layer of earth are made mostly of rocks?
Hard rocks form the outer layer of the Earth (the lithosphere) which includes the crust and upper mantle. Rocks of the remaining mantle are in a plastic state, able to move, bend and deform without breaking.
How are the asthenosphere and lithosphere involed with plate tectonics?
The lithosphere is the brittle surface layer composed of the crust and uppermost mantle. The asthenosphere is the ductile upper mantle on which the lithosphere is able to move.
What are reasons for plate movement?
I recently did a report which included earthquakes, and I did a little research about your question. I'm not sure if what I found is entirely true, but the book I read said that scientists are not really sure. The book said that scientists thought that maybe it came from the mantle, where it is very hot. As the heat from mantle is released, it goes up to the crust in waves. These waves cause the tectonic plates to move with them.
What force causes warm molten rock to move upward to the mantle?
The force that causes warm molten rock to move upward to the mantle is called convection. Convection happens when parts of the tectonic plate break off and melt.
What force cause warm molten rock to move upward in the mantle?
When a tectonic plate reaches a certain depth in the mantle, the heat and pressure from being so close to the Earth's core causes certain parts of the plate to melt. The section of the plate that has melted becomes lighter in weight than the rocks surrounding it. This causes it to rise and move upwards in the mantle.
What may be the main cause of the plates to move?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move.
Tectonic plates move by sliding on the molten upper part of the?
mantle
What happen to the crust when the molten rocks move upward?
The crust melt's because the molten rock's are at a really high temperature.
Where is a mantle convection current most likely to move upward?
ocean ridge
How do the divided plates in the earth's upper mantle move?
Tectonic Plates are floating on the semi-molten Mantle. Currents in the molten layer, eruptions of new lava round the edges, and the forming of deep ocean volcanic ridges, help to move the plates across the Earth's surface.
What makes the plate move?
Plates move because of the intense heat in the Earth's core. The heat causes molten rock in the mantle layer to move.
What is convection and how does it cause plates to move?
What is convection and how does it cause plates to move? What are the consequences of convection in the mantle?
What may happen to the leading edge of plate as it continues to move downward?
The edge of the plate will heat up and become part of the molten mantle.
Is magma the idea that the earth's crust is broken into plates that move on top of the mantle?
The idea that the earth's crust is broken into plates that move on top of the mantle is known as the theory of plate tectonics.Magma is the name given to molten rock below the Earth's surface.
Why is it that the mantle can easily move?
cause i rock y do u think
