What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
The convention that causes earths magnetic field happens in earths?
core
Which layer of the earth does convection take place in?
convection takes place in the outer core......... i think
Do convection currents occur in the mantle or the outer core?
The answer is that convection currents occur in both. Convection currents are just natures way of moving heat from one place (deep in the earth) to another place (closer to the surface) in the most efficient way possible.In the outer core, convection happens because the magma is liquid, so it flows easily. Also, since it contains moving charged particles, most scientists believe that the outer core generates the Earth's magnetic field.Convection curents also happen in the mantle, but they are slower because the mantle is mostly solid, so it flows very slowly. Convection currents in the mantle are believed to drag the tectonic plates with them, causing the continents to drift over long periods of time.Well the Earth's magnetic field is a result of the convective movement of the outer core.
Are there convection currents in the asthenosphere?
The lithosphere is generally thought of as the crust and outer mantle of the earth. They're solid, and there are no convection currents in solids as we normally think of them. As we move inward toward the core of the earth, we begin to encounter molten rock (magma), and convection currents exist in this superheated fluid.
Where does the heat come from that drives this convection current the mantle?
The heat comes from the outer core, which provides the heat.

Where does convection occur on the sun?
The core

How is the mantle like the outer core?
they both have convection currents

Why does convection occurs in the athenosphere?
heat from the outer core and the mantle when it drifts up to the asthenosphere it causes convection.
Does In the outer core flows water currents?
No. The outer core is made of iron and a lighter element, probably nickel. There is no free water in the outer core. But the outer core is liquid, and that liquid does circulate ("convection"). That circulation is what generates the magnetic field.
What happen as thermal energy is transferred from the core to the mantle?
CONVECTION CURRENT is the answer.

Does convection occur in the core of a star?
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
