What causes forced convection? – JanetPanic

2019-10-30 · This event will cause the mantle to sink down due to the pull of gravity. How do convection currents work? Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it.

Heat in the mantle comes from the Earth’s molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates. … The temperature difference between the upper and lower boundaries of the mantle requires heat transfer to occur.

Convection and Mantle Flashcards | Quizlet

The convection currents in the mantle are very similar to cooking a pot of soup. When a pot of soup is placed on a stove, the soup at the bottom of the pot is heated. As the soup warms up, it rises to the top of the pot. The cooler soup is more dense than the warm soup and begins to sink. This soup is then heated, and the process repeats.

What are effects of convection currents in the mantle

2013-8-2 · 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
