it works like air and a radiator the heated air rises and cools then falls and the process is repeated again and again

What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
What is the source of magma for intraplate volcanism?
Rift zone
What is tectonic convection?
Your probably referring to the magma convection currents within the mantle. Like normal heaing and cooling convection currents, the magma ebbs & flows, keeping the tectonic plates in motion.
What cause the motion of the plates?
Radioactive decay within the deep interior of the Earth causes convection currents in the magma of the mantle. The continental plates float on top of the mantle, and the currents push them. That is why continents drift.
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
What is a constructive force caused by the convection currents in the earth's mantle?
Convection currents in the earth's mantle cause the plates to move. When this happens, mountains can form.
Are there convection currents in the molten part of the earths interior?
Yes there are! That's why the plates move! It's caused by convection circulating the magma in the mantle creating currents!
What are effects of convection currents in the mantle?
The effects of convection currents in the mantle are an overall movement of magma, the shifting of plates, and the even distribution of heat. This helps to reduce the amount of earthquakes and volcano eruptions.
What name is given to the area where volcanoes often occurs because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
Which of the following is part of the Earths lithosphere SoilMagma None of these Mantle, magma, and soil Mantle?
magma
What is used to describe the continuous heating and cooling of magma in the mantle?
Mantle convection
What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
What is the rock of earths mantle?
plate tectonic and magma
What provides the force that causes magma to the surface?
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
Describe the mechanism of plate motion?
magma in the mantle rotates in convection cells. the magma then pushes the plates.
What is the source of magma for intraplate volcanism?
Rift zone
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
