Convection currents which affect weather and climate are created by?
Air convection currents are created by a combination of the sun heating the air closer to the equator making it rise and cooling it in the arctic regions making air descend. That combined with the rotation of the Earth causing a Coriolis Effect making the winds that travel west to east.
How do plate tectonics move?
Tectonic plates are segments of the Earth's lithosphere, the hard rocky outer shell composed of the crust and the uppermost mantle. This shell is divided by lines of faults, ridges of plate creation, and zones of plate destruction. All in all, there are roughly 30 tectonic plates which cover the entire surface of the planet. Plates can be composed of oceanic crust, continental crust, or a combination of both. Plate movements occur because the layer of Earth directly below the lithosphere, the asthenosphere, is hot enough, and under enough lithostatic pressure to prevent its melting, that it can deform without fracture. And although convection of heat does play a role in the movement of lithospheric plates, the convection currents themselves may be caused by gravity, which induces the sinking of older dense slabs of oceanic crust at subduction zones (a process known as 'slab pull'). The energy driving all of these processes is heat from the interior of the Earth derived from radioactive decay and residual heat from Earth's formation, and gravity which results in slab pull and push.
What function do the wind-driven currents play in the transport of heat energy in the oceans?
I actually don't really know the whole answer, so here it goes... (If you actually want to know the answer go to a web page and find it out!) Hope this helps, and have a nice day!
What roles do radiation play in heating and cooling the earth?
Radiation transfers heat from one object to another. It does not require any particles unlike conduction and convection. Radiation travels in the form of electromagnetic waves.
How do oceans redistribute earth's heat?
I recently saw the movie An Inconvenient Truth, and I'm pretty sure that ocean currents carry the heat in a large cycle around the worlds oceans.
What role do convection currents play as you heat a pot of water?
The role convection currents play as you heat a pot of water is transferring heat by movements of a liqiud or a gas because when when convection occurs it occurs in a circular pattern.
How are convection currents important in the Earth's system?
Deep, cold-water currents play an important role in creating the ocean oasis of the film. Convection currents play a role in the circulation of fluids. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks.
Is an egg frying in a pan conduction?
This is a more complicated question than you might expect. There are three basic way heat moves, convection, radiation, and conduction. Convection moves heat around by the rising and falling (currents) of some medium like air or water. The currents form, because heated material (in general) is less dense than cooler material. Therefore, convection *never* happens in the absence of gravity. Radiation is always in the form of light, specifically infrared. The warmth you feel when sunlight touches your skin is this kind heat. Lastly, there's conduction where heat moves from one thing to another by contact. Frying pan cooking (dry) primarily uses conduction, but radiation and convection do play roles. Frying pan cooking (with oil) primarily uses convection, but conduction is involved if the food sticks to the bottom.

What three things play a role in convection?
Heat source, fluid density, and constraining factor (ie the glass for a glass of water, thermal gradient for the atmosphere) are three things that play a role in convection.

What role does heat play in the rock cycle?
Heat energy from the sun causes water to change to a liquid to a gas

What distributes heat and moisture around the Earth?
Ocean currents as well as winds distribute heat and moisture around the earth. Winds can bring in cold fronts or warm fronts.
How do convection currents affect the rock cycle?
Convection is thought to play important roles in the earth. It is the main way heat is transferred from the interior to the exterior sections of the planet. It also plays a part in how the earth's plates move. Shut theft up
What role does mantle convection play in plate motion?
Convection currents in the mantle create plate tectonics.
How is the heat energy transferred from the walls of the kettle?
Heat transfer from kettle wall is both convection and radiation but convection play the major role on the temperature below 100 oC. Air expand on contact of hot surface and float upward since it is lighter than surrounding air cause stream of air come into contact of the kettle surface result to rapid heat loss.
