Convection in the mantle drives the movement of tectonic plates on the Earth's surface. Hot molten rock rises in convection currents, cools near the surface, then sinks back down in a continuous cycle. This process is responsible for the geological phenomena of plate tectonics, including the formation of mountains, earthquakes, and volcanic activity.

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 general result of the motion of convection currents in the mantle beneath the Atlantic ocean?
The general result is to make the ocean basin wider.
If the mantle and the core are extremely hot why is the heat coming from these layers not felt on the earths surface?
Rock is a very poor conductor of heat and there is quite a lot of it between the surface and the mantle. As a result heat conducts to the surface very slowly and quickly radiates into space. As a result the vast majority of heat at Earth's surface comes from the sun. The heat from the mantle is felt at erupting volcanoes where magma, which ultimately gets it heat from the mantle, reaches the surface.
Why are there convention current s in the mantle?
Convention? You mean convection! The mantle is not solid but molten, although extremely viscous, and heated by radio-active decay. Since the only escape for the heat is conduction through the crust and in lava, the consequent temperature gradients create convection currents.
What regions was the result of plumes of hot mantle rising in a hot spot within a plate?
the islands of hawaii
When does circular movement of the magna in mantle happen?

Who was in charge of the Constitutional Convention?
The delegates elected George Washington to preside over the convention. The result of the Convention was the United States Constitution.

What was a result of the Monterey Convention?
Delegates were electaed.
What was the result of the convention?
The U.S. ConstitutionThough the official purpose of the Constitutional Convention was to revise the Articles of Confederation the convention culminated with the signing of a new document, the U.S. Constitution.
What was the outcome of the Constitution convention?
It was initially the "Grand Convention" or "Philadelphia Convention", not the Constitutional Convention, as it had been called in 1787 ostensibly to amend the Articles of Confederation. But the result, nonetheless, was the new US Constitution.
Explain why cool rock material sinks when convention takes place in the mantle?
Cool rock material sinks in the mantle during convention because it is more dense than the surrounding warmer rock. As the cooler rock sinks, it displaces the warmer rock, creating a cycle of sinking and rising that drives mantle convection. This process helps transfer heat in the Earth's interior and drives plate tectonics.
What was the result of the Monterey Convention?
The constitution of the new State of California.
Crust sinks deeper into the mantle as a result of increased crustal?
Earth science
What was the result of the Convention on Nobles?
The nobles were removed of their titles and their land was taken away.
What was the major result of the Hartford convention?
It established the potential for states to secede from the republic
