When the heat source is removed from a fluid convection ...

Apr 08, 2022 User: When the heat source is removed from a fluid, convection currents in the fluid will a. speed up. b. change direction.c. eventually stop. d. continue at the same rate forever. Weegy: When the heat source is removed from a fluid, convection currents in the fluid will: eventually stop. Score 1 User: Mantle material rises in convection currents because heated …

What causes convection currents inside the earth crust ...

Apr 14, 2020 Differential heating leads to convection currents inside the earth crust. Explanation: The convective current in the earth's crust is a result of the heat that is released from the interior of the earth as the lighter less dense and warm material rises and the denser cooler material sinks through its own weight by the process of subduction usually in the ocean …

During ventilation what is the direction of the convection ...

Apr 17, 2022 Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. …. For instance, a hot radiator heats the air immediately around it. The air rises toward the ceiling, pulling cooler air down from the ceiling into the radiator to be heated.

What is the heat source that drives convection currents in ...

Apr 27, 2013 The heat source for the convection currents in the mantle is the sun? The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are ...

Chapter 1 Section 2: Convection Currents and the Mantle

Convection A convection current is the flow that transfers heat within a fluid. This continues as long as heat is added. Without heat, convection currents will stop as all material reaches the same temperature. Convection in Earth’s Mantle, Pg. 27 Earth’s mantle responds to heat. The heat source is the Earth’s core and the mantle itself.

Convection and the Mantle

Convection currents continue as long as heat is added to the fluid. Convection currents flow in the asthenosphere. The heat source for these currents is heat from Earth’s core and from the mantle itself. Hot columns of mantle material rise slowly. At the top of the asthenosphere, the hot material spreads out and pushes the cooler material ...

Convection Currents - What are Convection Currents ...

Convection is a process of heat transfer by the movement of fluids (gas or liquid) between regions of various temperatures. If convection occurs naturally it is called natural convection or free convection. If convection is forced to occur, say, if fluid is circulated using a pump or a fan, it is called forced convection.

what are convection currents and what causes them ...

Dec 14, 2021 What Are 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 atmospher

How do convection currents move the crust? -

Feb 21, 2020 How do convection currents move the crust? Convection currents happen in fluids with a heat source. The core heats up the magma and causes a convection current. When magma comes to the top of the mantle, it pushes against tectonic plates, which are huge slabs of rock which the crust rests on. Click to see full answer.

What causes convection currents in the atmosphere?

Feb 26, 2020 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. Click to see full answer.

Which layer of the Earth has convection currents?

Jan 05, 2020 Convection currents happen in fluids with a heat source. The core heats up the magma and causes a convection current . When magma comes to the top of the mantle, it pushes against tectonic plates , which are huge slabs of rock which the crust rests on.

What causes convection currents in earth's mantle ...

Jan 19, 2017 Convection currents is formed via heating and cooling of the fluid which changes in the fluid density with the hand of the force of gravity. The currents take place in the core and the mantle. Heat in the mantle is brought about from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending ...

How does the mantle move the crust? -

Jan 29, 2020 How do convection currents move the crust? Convection currents happen in fluids with a heat source. The core heats up the magma and causes a convection current. When magma comes to the top of the mantle, it pushes against tectonic plates, which are huge slabs of rock which the crust rests on.

How do convection currents work? - Best answer 2022

Mar 03, 2022 convection currents are a process in which the materials inside the mantle heat up and rise to the surface whilst the cooler liquid sinks; as it sinks it then heats up and rises again. This continuous cycle is established: hot liquid rising, cold liquid descending. These currents cause the tectonic plates to move.

What Causes Convection Currents in the Earth's Mantle?

Mar 24, 2020 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, break apart the plates at areas referred to as ...

Mantle convection with continental drift and heat source ...

Nov 01, 2013 We conducted numerical simulations of convection with a two-component fluid (heat source material and mantle material) in a two-dimensional rectangular box, with a height of 2900 km and an aspect ratio (width/height) of 4, together with the reflection boundary condition in the side boundaries.Physical properties (density, heating rate, and transition) of the heat …

what is the source of heat in a mantle convection currents ...

Nov 03, 2020 Answer: The source of heat in a mantle convection currents comes from the Earth's molten outer core, decay of radioactive elements and, in the upper mantle, friction from descending tectonic plates.. Explanation: The primary sources of thermal energy for mantle convection are three: (1) internal heating due to the decay of the radioactive isotopes of …

What causes convection currents to occur in the mantle. a ...

Oct 10, 2021 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.

What causes the convection currents in the mantle ...

Sep 18, 2018 Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere.
