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.
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!!
What are some examples of convection currents in everyday life?
The only one I can think of off the top of my head, is a kettle boiling water :) Hope this helps! : ) : )
What makes the strong winds on earth?
Strong winds result from convection currents in the air, which result from sunlight, which for various reasons will heat some air more than other air.
What is a convection current current?
Convection currents are vertical movements of fluids driven by heat. Hot fluids rise because they are less dense than cold fluids which sink. The best example would be soup boiling - stuff in the soup comes to the surface over the flame and sinks back towards the edges of the pot. --------------------------------------------------------------------------------------- Current caused by the expansion of a liquid, solid, or gas as its temperature rises. The expanded material, being less dense, rises, while colder, denser material sinks. Material of neutral buoyancy moves laterally. 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.

Where does the heat come from that drives the convection currents in the mantle?
Some is fossil heat, some from radioactivity.
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 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.
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 create ocean currents?
Sunlight warms the waters on the ocean surface. Some heat energy is transferred to cooler waters through convection.
What in earths mantle causes tectonic plates to move?
Convection currents in the mantle are what causes tectonic plates to move. Uneven heating of the mantle results from radioactive decay of some long-lived isotopes in the mantle, which are not evenly distributed.

Why do convection currents not occur in some components of the structure of the earth?
Convection currents can occur in either a gas or liquid medium but not in a solid medium (so you can have them in air, and you can have them in magma, but you can't have them in solid rock) and they only occur when there is a temperature difference, so that hotter, less dense material will rise, and colder, denser material will sink.
