The contact zone is called a cold front.
The atmosphere moves in masses. When two masses collide they are called fronts. When a cold air mass goes into the land occupied by a warm mass it makes a cold front. The opposite makes a warm mass.
Convection
Particles in a gas or liquid moving from a region of higher concentration to a region of lower concentration represents passive transport. This does not use energy.
Stormy
Stormy
a cold front
It is called a subduction zone.
Genetic flow?
Heat transfer by contact is called conduction.
The process in which particles move from high to low concentration is called diffusion .
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.
Diffusion
Decrease
When a region of higher concentration to a region of Lower concentration against the gradient which requires Energy is called Active Transport
their lots of moves that are super effective in the unova region but i don't know the moves because their to many moves that are very effective
The bit a on a metronome that moves is called a 'pendulum'.
This is called convection. One part of the fluid is heated and when it moves to a region of less energy it gives up some heat.
