Heat transfer by contact is called conduction.
heat moves from the hot to cold object by conduction
It moves by conduction and radiation.
Conduction
Light refracts becuase it moves at different speeds through different substances.
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".
The bending of light rays is called diffraction. It happens because light actually moves at different speeds in different substances. When light strikes a border between two substances (such as air and the glass of a contact lens) at angle, the edges of the wave-front reach the new substance at different times. Thus the different sides of the light ray change speeds at different times and the light ray bends.
It refracts some and reflects some.

This is true. We have just learned about this in are physical science class. The way the current moves through the ocean can cause different temperatures at different places. hope i could help

Magma moves, it erupts out of volcanoes, and this can cause substances of different density to mix together. If these substances remained liquid, they would eventually settle out into layers by density, but if the rock hardens before this happens, then you have permanent mixing.

Different temperatures make currents, the wind could cool down or heat up the surface water.
