Deserts receive little rainfall.
Filtering is a physical change. It takes out solids (mud) suspended in the water but doesn't change the water molecules themselves.
Yes.
A harsh climate, little rainfall.
Tundra
when its not a lot of rainfall
it gets little rainfall because it is a desert
No molecules are chanced, thus it is NOT a chemical chance. It's not much of a physical change either; the pressure inside is just a little bit higher.
high pressure most likely
Deserts receive little rainfall.
Antarctica and the Atacama Desert receive little rainfall.
A little of both...
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Deserts get little rainfall and some of them are quite hot - but not all. There are cold deserts also.
a physical change....? hope that helped a little.
The importance of physical change is that :-1) No new substance is formed.2) It is a temporary change.3) It is easily reversible.4) Very little heat energy is absorbed or given out.The mass of a substance does not alter in a physical change.
