Explanation:
On our planet we can survive thanks to a layer of different composition of gases that surrounds the whole Earth. This layer remains on Earth thanks to gravity. It is the earth's atmosphere, and it is difficult to determine exactly its thickness, since the gases that make it up become less dense with height, until they practically disappear a few hundred kilometers from the surface.
The atmosphere fulfills various functions for life on the planet and without it we would not be able to have life as we know it.
a control helps to increase the reliability of the results. it allows a scientist to compare it to other group(s) in an experiment. if a scientist notices a significant different btwn the control and the other groups, he can logically conclude that the independent variable has an impact on the dependent variable.
a variable is any factor, trait or condition that can exist in differing amounts or types. there are usually three tpes of variables in experiments: the independent, dependent and contolled. the independent variable variable is the one that is changed by the scientists to figure it's affect on something.
