The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
What else can I help you with?
How many general methods of energy transfer are there?
There are three general methods of energy transfer: conduction (transfer through direct contact between objects), convection (transfer through fluid motion like air or water currents), and radiation (transfer through electromagnetic waves).
What three processes move energy through the geosphere hydrosphere biosphere and atmosphere?
The processes that move energy through the geosphere, hydrosphere, biosphere, and atmosphere are radiation (transfer of energy through electromagnetic waves like sunlight), convection (transfer of energy through fluid movements like ocean currents and air masses), and conduction (transfer of energy through direct contact between materials).
What are three processes that move energy through the geosphere hydrosphere biosphere and atmosphere?
Three processes that move energy through the geosphere, hydrosphere, biosphere, and atmosphere are photosynthesis, convection currents, and the water cycle. Photosynthesis converts solar energy into chemical energy in plants. Convection currents transfer heat energy from the Earth's interior to the surface. The water cycle involves the movement of water and energy between the atmosphere, land, and oceans.
How is energy transferred within the earth and atmosphere and throughout the oceans?
Energy is transferred within the Earth through conduction, convection, and radiation. In the atmosphere, energy is transferred through processes such as convection, advection, and radiation. In the oceans, energy is transferred through currents, waves, and tides, as well as through processes like conduction and convection.
What are convection currents created by?
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
What kind of energy does convection currents transfer through a fluid?
Convection currents transfer thermal energy through a fluid. This process involves the movement of warmer and cooler parts of the fluid, which causes the transfer of heat energy.
What are convection currents and what do they transfer?
thermal energy
How does thermal energy pass through a sheet of glass?
convection currents are used to transfer thermal energy through layers of glass
The transfer of what form of energy leads to convection currents?
Heat Energy
Is convection current kinetic energy before transferring?
In a convection current the kinetic energy will most likely be a small part of the total as the rate of flow won't be very high. Most heat transfer in convection will be simply thermal energy transfer, ie from a warmer place to a cooler one.
Where is one example of where energy transfer by convection is occurring?
One example of where energy transfer by convection occurs is in the Earth's atmosphere. Heat from the sun warms the air near the Earth's surface, causing it to rise and transfer heat to higher altitudes through convection currents.
Which process do air currents transfer heat energy throughout the room?
convection
A method of heat transfer when energy is transferred by currents in a liquid or gas?
convection
How is the transfer of energy in a pan of hot water similar to the transfer of energy in the sun convective Zone?
In both cases, heat is transferred via convection.
How many general methods of energy transfer are there?
There are three general methods of energy transfer: conduction (transfer through direct contact between objects), convection (transfer through fluid motion like air or water currents), and radiation (transfer through electromagnetic waves).
How does heat transfer energy?
draughts transfer heat energy through convection
Which process causes the transfer of energy by air currents within the Earth's atmosphere?
convection
