Many scientists believe that crustal plate movement occurs because of convection cells contained in earth's?
mantle. Heat from the Earth's core causes convection currents in the mantle, which drives the movement of the tectonic plates on the surface. This process is known as plate tectonics and is responsible for shaping the Earth's surface over millions of years.
The theory of plate tectonics explains the movement of the plates by convection cells in which layers?
The theory of plate tectonics explains the movement of plates by convection cells in the Earth's mantle. These convection cells are caused by the heat from the Earth's core, which creates movement in the semi-fluid asthenosphere layer of the mantle, leading to the movement of the rigid lithospheric plates above it.
What does the convection cell do to the lithosphere?
Convection in the mantle creates movement of tectonic plates, which can affect the lithosphere by causing it to move, leading to processes like subduction or seafloor spreading. The convection cells help drive the movement of the lithospheric plates on the Earth's surface.
In the mantle heat is transferred as soft rocks flow slowly in cycles known as?
In the mantle, heat is transferred through convection, where soft rocks flow slowly in cycles known as mantle convection cells. These cells are responsible for the movement of tectonic plates and the transfer of heat from the Earth's interior to the surface.
What is the source of energy drives the movement of the lithosphere plates?
Asthenosphere

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.

How do plates push together?
Plates push together at convergent plate boundaries due to the movement of the underlying molten mantle material called convection currents. This movement causes plates to collide, leading to subduction where one plate is forced beneath another, or crustal compression where plates are pushed together. This process can result in the formation of mountain ranges or deep ocean trenches.
When does circular movement of the magna in mantle happen?
Convention cells in the molten outer core cause convection cells in the mantle.
What does the convection cell do to the lithosphere?
Convection in the mantle creates movement of tectonic plates, which can affect the lithosphere by causing it to move, leading to processes like subduction or seafloor spreading. The convection cells help drive the movement of the lithospheric plates on the Earth's surface.
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 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.
What is the definition of convection cells and how do they contribute to the movement of heat and energy in the Earth's atmosphere?
Convection cells are circular patterns of air movement in the Earth's atmosphere caused by differences in temperature and pressure. These cells help distribute heat and energy by transferring warm air from the equator towards the poles and cold air from the poles towards the equator. This movement plays a crucial role in regulating the Earth's climate and weather patterns.
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.
