Which of these best describes convection currents?
Which best describes the convection currents? Convection currents move thermal energy from the stove to the pot, and then from the pot to the water.
How do you describe a mantle convection?
0:332:56Mantle Convection explained by Peter Bunge – YouTubeYouTubeStart of suggested clipEnd of suggested clipConvection is a process that moves heat. Around hot material comes up cooled material goes down andMoreConvection is a process that moves heat. Around hot material comes up cooled material goes down and in the interior of the earth convection occurs throughout the Earth's outer core.
What are convection currents in the mantle simple?
The two processes work in conjunction with each other. Convection currents in the air and sea lead to weather. 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.
What cause convection currents in Earth’s mantle?
Heat from the core and the mantle itself causes convection currents in the mantle. Hot columns of mantle material rise slowly. At the top of the asthenosphere, the hot material spreads out and pushes the cooler material out of the way. This cooler material sinks back into the mantle.
Are convection currents fast or slow?
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carrying heat from the interior to the planet's surface.
What happens during convection?
convection, process by which heat is transferred by movement of a heated fluid such as air or water. Natural convection results from the tendency of most fluids to expand when heated—i.e., to become less dense and to rise as a result of the increased buoyancy.
Which best describes Earth’s mantle quizlet?
Which statement BEST describes the Earth's mantle? The mantle is the 3rd hottest layer and is the 3rd in terms of the amount of pressure present.
What do convection currents do?
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth's ocean currents, atmospheric weather and geology.
What causes convection in the mantle quizlet?
Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion. Heat from the core and the mantle itself cause convection currents in the mantle.
What is convection short answer?
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.
What best describes Earth’s mantle?
The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
Which of the following best describes the Earth’s mantle *?
A.It is a thin layer of solid rock on the surface. Explanation: Hope you like my answer .
What are convection currents under the Earth?
The mantle within the earth's surface flows due to convection currents. These currents are mainly caused by a very hot material present in the deepest part of the mantle which rises upwards, then cools, sinks, again and again, repeating the same process of heating and rising.
What is one effect of convection currents in the mantle?
Convection currents within the mantle provide one potential driving force for plate movement. The plastic movement of the mantle material moves like the flow of mountain glaciers, carrying the lithospheric plates along as the convection movement in the mantle moves the asthenosphere.
What causes convection currents on Earth quizlet?
Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion. Heat from the core and the mantle itself cause convection currents in the mantle. Convection currents take place in the core and the mantle.
What do convection currents occur in?
Convection currents occur within:
- the geosphere – plate tectonics.
- the atmosphere – wind.
- the hydrosphere – ocean currents.
What is convection in the Earth?
Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.
What is meant by convection current?
Definition of convection current 1a : a stream of fluid propelled by thermal convection. b : thermally produced vertical air flow. 2 : a surface charge of electricity on a moving body — compare convection sense 3c.
What types of currents are formed in the mantle?
Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.
What is convection current in tectonic plates?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
Where do convection currents happen in the Earth?
Convection currents occur within: the geosphere – plate tectonics. the atmosphere – wind. the hydrosphere – ocean currents.
How do convection currents in the mantle move tectonic plates?
Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
Where do Earth’s convection currents occur quizlet?
The Earth's crust is split into many pieces called plates. There pieces are moved by Convection currents, which occur within the Mantle. Convection currents occur when magma heats up near the core and rises.
How does convection in Earth’s mantle affect?
This flow, called mantle convection, is an important method of heat transport within the Earth. Mantle convection is the driving mechanism for plate tectonics, which is the process ultimately responsible for producing earthquakes, mountain ranges, and volcanos on Earth.
What are convection currents in plate tectonics?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
What do convection currents cause?
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth's ocean currents, atmospheric weather and geology.
What does convection current occur?
Convection currents are present in the air– A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air. Another good example of convection current is wind.
Why are there convection currents in the mantle quizlet?
Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion. Heat from the core and the mantle itself cause convection currents in the mantle.
Where do Earth’s convection currents occur?
Convection currents in the Earth occur in the mantle. The core of the Earth is extremely hot, and material in the mantle close to the core is heated…
What is convection currents quizlet?
Convection currents are the transfer of heat through the Earth's magma. They can be found in the mantle. The hottest part of the Earth is the core. the heat from the core is transferred into the lower mantle.
