When the heat source is removed from a fluid convection currents will?

When the heat source is removed from a fluid convection currents will?

Сonvection currents will be stopped because there is no heat to keep them moving.

What happens to the convection current when the heat source is applied to it?

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. This fluid in turn is heated, rises and pulls down more cool fluid.

How does convection remove heat?

Convection is the process of losing heat through the movement of air or water molecules across the skin. The use of a fan to cool off the body is one example of convection. The amount of heat loss from convection is dependent upon the airflow or in aquatic exercise, the water flow over the skin.

What will happen to the convection currents in the earth if the heat source cools?

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.

When the heat source is applied to fluid convection currents in the fluid will?

Answer: The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, the hot fluids tend to rise, whereas cold fluids tend to sink.

Which of the following occurs because of convection?

Which of the following occurs because of convection currents? Tectonic plates on the crust move.

What happens when convection currents occur?

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 is current convection?

A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. …

Is convection heat transferred?

Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

How does convection current affect the internal heat of the earth?

Magma in the Earth’s mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

What are the convection currents and what causes them?

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
