The process of convection occurs when there are significant differences in density, pressure or temperatures of two - or more - different layers of matter in liquid, gas, solid or plasma state.

Is heating of air touching a hot surface conduction or convection?
convection
Where does convection happen?
Convection refers to the transfer of heat energy by the motion of a fluid such as air or water caused by differences in temperature within the fluid. Therefore convection happens wherever there is a fluid with a temperature gradient. This means that convection is happening continuously in the air around us and in bodies of water. A car heater and a convection oven are also considered to transfer heat by convection, but this is using the term liberally since the movement of the fluid (air) in these two cases is caused by a fan, not temperature gradient. So, while not perhaps being absolutely accurate examples of convection, still the heat is transferred through fluid motion.
What three factors set convection in motion?
The three factors that set convection currents in motion are: the heating and cooling of fluid, the change in it's density, and the force of gravity.
Is there a relationship between convection and albedo?
break up withha
What force of nature is responsible for continental drift?
Most definantly the convection
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Where does convection occur?
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
Where does convection occur on the sun?
The core
What are convection currents and in which layer do they occur?
no
How does heat loss occur?
It can occur through conduction, convection and radiation.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
What does convection only occur in?
Convection only occurs in fluids. Fluids are gases or liquids.
Where in the earth do convection currents occur?
Convection currents take place in the mantle.
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
In which layer of earth does convection occur?
mantle
In which state of water does convection occur?
nothing
Where do convection and conduction occur in the atmosphere?
BLA
