Many scientists believe that crustal plate movement occurs because of convection cells contained in earth's?
Convection in the mantle is thought to be one of the potential driving mechanisms of plate movement.
What is the source of energy drives the movement of the lithosphere plates?
Asthenosphere
The theory of plate tectonics explains the movement of the plates by convection cells in which layers?
mantle or upper mantle
Movement of plates on earth's suface?
Constant. The tectonic plates of the earth are floating on the mantle, convection current cells cause them to slide around.
How do convection cells Earth's atmosphere cause high- and low- pressure belts?
The convection cells radiate heat.

How do crustal plate came to existence?
They are the solid crustal rock floating on the top of a mantle convection cell. They formed the same way slag forms on the tops of convection cells in the molten metal in a smelter furnace. Sections of the mantle also float on the tops of convection cells in the molten metal of the liquid core. If you want to watch the tops of some convection cells form and move, get a cup of some hot drink (e.g. coffee or tea) and let it sit undisturbed for a minute or so to let all currents but convection currents stop. When you look at the surface of the hot drink it will be covered in very tiny polygons. These polygons are the tops of convection cells in the drink, don't they look something like a miniature map of crustal plates? Watch as they expand, contract, and move about.
When does circular movement of the magna in mantle happen?
Convention cells in the molten outer core cause convection cells in the mantle.
What is the source of energy drives the movement of the lithosphere plates?
Asthenosphere
The theory of plate tectonics explains the movement of the plates by convection cells in which layers?
mantle or upper mantle
What causes convection cells turn down?
Convection cells turn down because when the cells are away from the heat source the cells begin to cool. If cells are cooler they are more dense. Therefore, the change in density causes the cells to sink.
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.
How do scientists think earths crust moves?
The crustal plates (made mostly of low density granitic rock) float on the mantle (made mostly of high density basaltic rock). Convection cells in the mantle move the floating crustal plates around.

What are tectonic plates referring to?
The plates of crustal rock floating on the mantle rockand being moved by the flow of mantle rock in convection cells driven by the heating of radioactive decay deep in the core and lower mantle.
A salmon moves from a saltwater ocean to a freshwater river. What takes place in the salmon's cells as it moves?
The cells fill with water because of the movement of water by osmosis. (APEX)
How do convection cells in earth atmosphere cause high and low?
The convection cells radiate heat.
