Convection currents happen in the mantle and cause tectonic plates to drift.
The earth is made up of the iron and nickel core, then the mantle then the crust. And the earths surface is made up of tectonic plates. These plates move due to convection currents.
convection currents work when heated water cools then goes to the bottom then heats back up
convection,radiation,and conduction?
There are many possible forces or mechanism associated by continental movement.include;sea-floor spreadingthermal plume phenomenaslab-push at mid oceanic ridge.slab-pull at subduction zoneNote that all this mechanism work together
On the earth.
Basically, Density is the result of an amount of mass packed into a given space. The more mass packed into a space, the denser the object and the less mass, the less dense it is. Convection is heat transfer by fluid or liquid movement. It is found in the air (as wind) in the oceans (as currents) and in the mantle of the Earth (it affects plate movement). Warm air or water or mantle rises and is replaced by the cooler mass. In the case of the air and water, the cooler, denser air and water falls due to having more mass and gravity pulling on it. In the mantle, the cooler mantle is falling and its density allows the core's gravity to pull on it. But the deeper into the mantle, temperature increases instead of decreasing due to pressure in the outer and inner core. Density and convection work together to help keep the balance of systems in all areas of Earth's processes.
If the glider has a roasing chicken inside, it will cause some convection waves, this will lift the Glider up.
it works by earth

The reason is because Obama was sworn into office again and the United states is gonna break down. If that is right then it is bacon, everything is right because of bacon.
It is transferred by the energy of photons and heat radiation. Convection doesnt work as there is vacuum between sun and earth.

Our Earth's outer core consists of a liquid iron, which is highly conductive. As this liquid moves via convection (the same way water boiling in a pot moves via convection), electrical fields are generated, which then create a magnetic field -- a farily simple electromagnetic. The EXACT mechanics of this are difficult to work out, but has been done.
no it does not.
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.
Conduction: Heat transfer by direct contact, such as from an electric coil on a stove to the pot. Convection: Heat transfer though the air, such as in an oven. Radiation: Heat transfer via waves, such as from the Sun to Earth.

Convection ovens have a fan in them which circulates the air. That makes for faster cooking (20%)
