Q:

How do convection currents move tectonic plates?

A:

Quick Answer

Convection currents move tectonic plates when there is heat inside the mantle that is rising and falling. The radioactive decay in the core is responsible for the convection currents.

Full Answer

The convection currents in tectonic plates occur in the geosphere. The radioactive decay of elements is responsible for the heat deep within the earth, and this results in the creation of magma. Magma is a type of material that can be semi-fluid or completely fluid. It is very hot and when it starts to cool, it forms into igneous rock and lava. Convection currents also occur in wind in the atmosphere and in ocean currents in the hydrosphere.

  • Q:

    What causes convection currents?

    A:

    Convection currents are caused by an uneven temperature within something. Convection currents happen within the Earth's magma, water and air. It can happen in anything that is not solid and has parts that are cooler or warmer than other parts.

  • Q:

    Where do convection currents flow in the Earth?

    A:

    Convection currents flow in the asthenosphere, immediately below the rocky outer lithosphere. Convection currents are one of three types of heat transfer, which involve the movement of energy from a warmer object to a cooler object.

  • Q:

    How do convection currents work?

    A:

    Convection currents move a gas or a fluid from one place to another and are created when there are differences in density or temperature within that gas or fluid. A convection current can also be thought of as a process that moves energy from one place to another. This process is sometimes referred to as convection heat transfer.

  • Q:

    What is a convection current?

    A:

    Convection currents occur in the Earth's geosphere, atmosphere and hydrosphere when heat is transferred from one place to another. Heat energy moves from hot places to cold places during convection.
