What process allows the tectonic plates to move?
Tectonic plates move due to a process called plate tectonics. It is driven by the movement of molten rock in the Earth's mantle, which causes the plates to slowly drift and collide with each other. This movement is caused by convection currents in the mantle, creating a continuous cycle of plate motion.
What are tectonic plates and how do they effect man kind?
Tectonic plates are the large fragments of earth's solid crust, floating atop the molten mantle. they effect mankind by providing us the shape of our landmasses, and various mountains and valleys created by their movement. Also, earthquakes, and to some extent volcanoes are caused in this way, and these can have dramatic effects on mankind.
When two plates collide what can happen?
When two oceanic plates collide, one may be pushed under the other and cause magma from the mantle to rise, forming a volcanoe or volcanoes. When two continential plates collide at a reverse fault tectonic earthquakes occur.
What does lithosphere movements cause?
Most earthquakes and volcanic eruptions occur near the collision of two lithospheric plates. These collisions may eventually result in fractures of the brittle underlying upper mantle. Fractures may cause the layers of crust to move vilolently as during an earthquake, or allow a path for molten magma to escape through the upper mantle to the surface in an eruption.
What results from an oceanic plate to oceanic plate convergence?
The convergence creates a trench where the more dense of the two plates flows downward toward the mantle. Earthquakes may occur in the area of the plate boundary, as well as volcanism.
Plates may move because of this type of movement in the mantle?
mantle
What is the name of the landmass that move?
You may be referring to either tectonic plates, which are huge shelves of the earth's crust that are floating of the molten mantle, or glaciers, which are mainly made of ice in addition to dirt and rock. Both of these things move very slowly.

Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools?
First the heat below the mantle makes even the solid part of the mantle flow very slowly as though it were very thick liquid. the hot rising part of the mantle cools as it nears the crust. as the cooling mantle moves sideways it drags along the plate floating on top of it. the arrows show the cooled mantle sinking back down. later on the mantle will may be get warm and rise again.
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.

What Plate may move because of this type of movements in the mantle?
Tectonic plates shift with other plate causeing either mountions or volcanoes
Why are the earths plates always moving?
Due to the heat of magma (molten rock) under the earth's surface. The heat causes convection currents, pulling and pushing the tectonic plates.

When two oceanic plates collide, one may be pushed under the other and cause magma from the mantle to rise, forming a volcanoe or volcanoes. When two continential plates collide at a reverse fault tectonic earthquakes occur.
How are the planets similar to the core mantle crust?
earths mantle extends to a depth of 2890 km, making it the thickest layer of Earth. The pressure, at the bottom of the mantle, is ~140 GPa (1.4 M). The mantle is composed of siligate rocks that are rich in iron and magnesium relative to the overlying crust. Although solid, the high temperatures within the mantle cause the silicate material to be sufficiently ductile that it can flow on very long timescales. convection of the mantle is expressed at the surface through the motions of tectonic plates. The melting point and viscosity of a substance depends on the pressure it is under. As there is intense and increasing pressure as one travels deeper into the mantle, the lower part of the mantle flows less easily than does the upper mantle (chemical changes within the mantle may also be important). The viscosity of the mantle ranges between 10 and 10 pa-s, depending on depth. In comparison, the viscosity of water is approximately 10 pa-s and that of pitch is 10 Pa·s. Soo Its Not ;)
What might have caused plates to move?
Tectonic plates may have moved by convection currents. The mantle is made of a much thicker, denser material, which causes plates to float on them like oil floats on water. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. A conveyor belt in a factory moves boxes like the convection currents in the mantle moves the plates of the Earth. I just did a report on this, and i love science so i know a bunch of facts such as these. I personally like to think of lava lamps in this particular topic. Hope this helped! :) ~NEK
What layer causes quakes?
the earth has 4 layers the crust the mantle the outer core the inner core the crust is divided into giant sections called plates on plate broundrys, where plate meets another plate, there can be volcanoes and many earthquakes may accur there. due to currents in the mantle these plates move very slowly and different plates travel in different directions so on the boundries the plates can get wedged together and stuck. when the plates finally give way a lot of energy is released and shockwaves travel out from that area. this is what we call an earthquake so earthquakes occur in the outter most layer of the earth also known as the crust
