What will happen to the convection currents in the mantle of Earth?

What will happen to the convection currents in the mantle of Earth?

Explanation: Convection currents within the Earth’s mantle are caused by hot material rising upwards, cooling, then dropping back toward the core. If the interior of the Earth were to cool enough for convection currents to stop, then the motion of the plates would cease, and the Earth would become geologically dead.

What will happen during mantle conduction when heat is transferred?

In conduction, heat is transferred as atoms collide. The rising and sinking of warm and cooler material is called convection. Conduction brings hot material up toward the surface. It brings cooler material down toward the core, and so on.

What happens to the heated mantle as it transfers its heat energy to the lithosphere?

As the heated mantle transfers its heat energy to the lithosphere, it becomes more dense than the surrounding magma and sinks back down towards the core.

What happens to convection currents as they heat?

convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks.

What process leads to convection in the mantle?

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet’s surface. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading.

How is heat transferred in the Earth’s mantle?

When the mantle convects, heat is transferred through the mantle by physically moving hot rocks. Mantle convection is the result of heat transfer from the core to the base of the lower mantle. Convection carries heat to the surface of the mantle much faster than heating by conduction.

What happens in the mantle of the Earth?

The transfer of heat and material in the mantle helps determine the landscape of Earth. Activity in the mantle drives plate tectonics, contributing to volcanoes, seafloor spreading, earthquakes, and orogeny (mountain-building).

What is the effect of heat in the mantle?

As the warmer material rises, it also cools, eventually pushed aside by warmer rising material and sinking back toward the core. Mantle material flows slowly, like thick asphalt or mountain glaciers. While the mantle material remains solid, the heat and pressure allow convection currents to move the mantle material.

What form of energy transfer is happening in the mantle?

Convection
Convection occurs in the Earth’s mantle because it is the most efficient way for the Earth to cool or dispose of its deep-seated heat content. In general, heat can be transferred by conduction, radiation or convection.

How do convection currents in the mantle work?

Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth’s crust, plates move apart. Where convection currents converge, plates move towards each other.

What happens to the convection currents in the mantle?

As the magma cools and solidifies, the convection currents will stop and the Earth will become geologically dead. Convection currents within the Earth’s mantle are caused by hot material rising upwards, cooling, then dropping back toward the core.

How is heat transferred from the core to the mantle?

In Earth’s mantle, large amounts of heat are transferred by convection currents. Heat from the core and the mantle itself cause convection currents in the mantle. Plumes of mantle rock rise slowly from the bottom of the mantle toward the top. The hot rock eventually cools and sinks back through the mantle.

How are convection currents used to transfer heat?

The convection currents also help transfer heat from Earth’s core, where magma is created through radioactive decay, to the mantle. This heat transfer continues through the layers of the crust until it reaches the surface. The convection currents, as they carry heat upward with the magma,…

How is convection related to the movement of magma?

Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection currents within the earth move layers of magma, and convection in the ocean creates currents.
