What is the transfer of energy that occurs due to density differences in the air?
Convection.
When you sit at camp fire objects beyond the fire seen swaying give the reason for it?
Differences in density in the air or gases (due to the heat) produce refraction. These differences in density change from one moment to another.
The movement of matter due to differences in density and the transfer of energy that results from this movement is called?
convection current
Does the flow that transfer heat within a fluid is called convection current?
Not unless the fluid is flowing due to temperature/density differences.
When electromagnetic energy travels from air into water the waves are bent due to the density differences between the air and water what is this bending called?
That is called "refraction".
Which way round does convectional current flow?
A convection current flows in a circular pattern, with warmer material rising and cooler material sinking (due to density differences). It should not be used with conveNtional current in electricty.
What is convection flow?
A convective flow is the motion of a fluid due to differences in density. These differences in density commonly occur due to temperature gradients. For example the circulating air flow in a room with a hot radiatior.
What is the transfer of energy that occurs due to density differences in the air?
Convection.
What is a good sentence for convection?
Convection is the movement of matter due to differences in density.
How are coduction and convection alike?
conduction is transfer of energy due to direct contact, convection is due to density differences
Which has the less density graphite or diamond?
Graphite is less dense than diamond, due to the differences in crystal structure.
When you sit at camp fire objects beyond the fire seen swaying give the reason for it?
Differences in density in the air or gases (due to the heat) produce refraction. These differences in density change from one moment to another.
What do hot spots and mid ocean ridges have in common?
rising magma moves due to density differences
The movement of matter due to differences in density and the transfer of energy that results from this movement is called?
convection current
What do you think subduction means?
subduction is when a piece of the earths crust slides back into the mantle due to density differences
What do mid oceans and hot spots beneath ocean plates have in common?
rising magma moves due to density differences
Is cycling good after age of 30?
If done with due consideration, cycling is always good.
