Convection currents transport energy around the globe by transferring heat from warmer regions to cooler regions through the movement of air and water. As warm air or water rises in one area, it displaces cooler air or water, creating a continuous cycle of movement that redistributes thermal energy over the Earth's surface. This process helps regulate temperatures and influences weather patterns on a global scale.

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.
Heat and moisture are distributed around Earth by and hellip?
Heat and moisture are distributed around Earth through processes like evaporation, convection, and atmospheric circulation. The Sun's energy drives evaporation of water from the surface, which then rises and condenses to form clouds. Winds and ocean currents help transport heat and moisture to different regions of the planet.
How is most of the heat energy in the atmosphere transferred?
Most of the heat energy in the atmosphere is transferred through convection, where warmer air rises and cooler air sinks, creating air currents. This process helps distribute heat around the globe and is a key driver of weather patterns.
How does the mantle get energy to move in convection currents?
The mantle gets energy to move in convection currents from the heat generated by the radioactive decay of elements within the Earth's interior. This heat causes the mantle material to become less dense, leading to its upward movement. The cooler, denser material then sinks back down, completing the convection cycle.
Where do convection currents happen?
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
What are convection currents are and what they do?
thermal energy
Which process do air currents transfer heat energy throughout the room?
convection
The type of energy called convection happens as a result of?
Convection currents
What are convection currents and what do they transfer?
thermal energy
How does a convection current transport energy across the globe?
Convection currents are created by temperature differences in the Earth's atmosphere and oceans. Warm air or water rises, carrying energy with it, while cooler air or water sinks. This continuous cycle of rising and sinking helps transport heat energy around the globe, contributing to the redistribution of heat and maintaining the Earth's climate system.
Does light consist of convection energy?
No, these are completely different. Light is an electromagnetic wave that can travel even in a vacuum (like space), whilst convection means transport of heat by currents of air or other medium, the currents being produced by the differences in density of the medium.
What 2 processes transport Earths energy surpluses poleward from the tropics?
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
The transfer of what form of energy leads to convection currents?
Heat Energy
What type of energy starts the convection currents in the ocean?
THE ENGERGY is Kinetical energy
What is the major source of energy for continental drift?
convection currents
How do surface currents transfer energy?
by convection
What is the link between the radioactive decay of the earth's core and convection currents?
The radioactive decay produces heat energy, which keeps the convection currents moving.
