Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.

How do convection currents contribute to eutrophication?

Some of the substances that give rise to eutrophication in a system naturally settle to the bottom. However, convection currents can bring them closer to the surface again.


Do scientists think plates are moved by convection currents or volcanoes?

Scientists believe that tectonic plates are moved primarily by convection currents in the Earth's mantle. Although volcanoes can play a role in some plate movements, such as at subduction zones, they are not the primary driving force behind the overall motion of tectonic plates.


Is it true that wind are examples of convection currents?

Yes, wind is a result of convection currents. The Sun heats up the Earth's surface unevenly, causing air to heat up and rise in some areas and cool and sink in others. This movement of air creates wind as it tries to equalize temperature and pressure differences.


Where do you find convection currents?

Convection currents occur in the asthenosphere.


Does convection current contribute to eutrophication?

It can is some cases. Some of the substances that give rise to eutrophication in a system naturally settle to the bottom. However, convection currents can bring them closer to the surface again.

What are some physical processes that occur inside of the earth and what has been theri effect?

Some physical processes inside the Earth include convection currents in the mantle, plate tectonics, and volcanic eruptions. These processes have effects such as the formation of mountains, earthquakes, and the recycling of Earth's crust.


Where does the heat come from that drives the convection currents in the mantle?

The heat that drives convection currents in the mantle primarily comes from the radioactive decay of elements such as uranium, thorium, and potassium. This heat causes the mantle material to become less dense, rise towards the surface, cool down, then sink back towards the core in a continuous cycle of convection.


What would happen to the convection currents in the mantle if earth's interior eventually cooled down?

If the mantle of the earth interior were to cool down the convection currents and plate tectonics would stop. That would mean that there would be no more earthquakes or volcanoes.


Which describes the way a convection current moves?

Convection currents are currents caused by the expansion of a liquid, solid, or gas as its temperature increases.while colder, denser material sinks.. Convection currents arise in the atmosphere above warm land masses or seas, giving rise to sea breezes and land breezes, respectively. In some heating systems, convection currents are used to carry hot water upwards in pipes. Convection currents in the hot, solid rock of the Earth's mantle help to drive the movement of the rigid plates making up the Earth's surface .


What create ocean currents?

Sunlight warms the waters on the ocean surface. Some heat energy is transferred to cooler waters through convection.


What processes within Earth cause geologic activity?

Plate interactions and Earthquakes. Also Convection Currents!! How earthquakes occur is when volcanoes erupt a earthquake happens some where in the world. when a Convection Currents happen inside the in the mantle!! Plate interactions create a folded mountain!!
