How does a convection cell turn up?
In a convection cell, warm air rises due to being less dense than cooler air. As the warm air rises, it creates a low-pressure area at the surface, causing cooler air to be drawn in. This cycle of warm air rising and cool air sinking creates the convection cell's overturning motion.
What causes the convection cell to turn up to point a?
The convection cell turns upward at point A due to the rising of warm air near the Earth's equator. As the warm air rises, it creates a low-pressure system, which causes the air to flow towards the poles at high altitudes. This flow of air completes the convection cell cycle.
How do convection currents in the mantle effect lithosphere movement?
Convection currents in the mantle drive the movement of tectonic plates on the Earth's surface. As the mantle heats up and rises near mid-ocean ridges, it spreads and pushes the plates apart. When the mantle cools and sinks back down near subduction zones, it pulls the plates back together. This process of convection and plate movement is known as plate tectonics.
The sinking of cold ocean lithosphere drives the motions of mantle convection through?
The sinking of cold ocean lithosphere drives mantle convection by creating a negative buoyancy force that pulls the lithosphere into the mantle. This movement displaces hotter, less dense material in the mantle, initiating a cycle of convection currents. These currents drive plate tectonics and heat transfer within the Earth's interior.
What are sections of the upper mantle called?
The upper mantle is divided into two main sections: the lithosphere and the asthenosphere. The lithosphere is rigid and includes the crust, while the asthenosphere is a semi-fluid layer beneath the lithosphere where convection currents occur.
What cause the convection cell to turn to the left at point b?
It hits the bottom of the crust (lithosphere) and has to turn left!
How does a convection cell turn up?

What is the lithosphere moved by?
The lithosphere, (The "gooey" part of the mantel that is between the crust) Is moved by convection currents.
Where in the earths layers are the convection currents found?
Lithosphere
What type of stresses broke Earth's lithosphere into plates?
The movement of convection currents in the mantle is believed to have caused the Earth's lithosphere to break into plates. These currents create stress within the lithosphere, leading to the formation of tectonic plates.
How convection currents are caused and how they move material in the mantle and lithosphere?
Because the mantle and lithosphere have gases or liquids that circulate
Name 2 layers of earth in which convection currents take place?
athenosphere and lithosphere
How do lithosphere plates move where convection currents rise?
They move apart.
What causes the convection cell to turn up to point a?
The convection cell turns upward at point A due to the rising of warm air near the Earth's equator. As the warm air rises, it creates a low-pressure system, which causes the air to flow towards the poles at high altitudes. This flow of air completes the convection cell cycle.
What process drives the lithosphere plates across the surface of earth?
The lower mantle convection
How do you think this convection cell might the crust material above it?
I think the convection cell might affect the crust because the convection cell is bigger than the crust.
How do you think this convection cell might affect the crust material above?
I think the convection cell might affect the crust because the convection cell is bigger than the crust.
