| What is the goal of technology? | to make it easier to access data | What are the two most abundant gases in our atmosphere? | Nitrogen and oxygen are the most abundant in the atmosphere. 78.08% Nitrogen, 20.95%Oxygen, |
| Why is the atmosphere important to us? | The atmosphere is important for two main reasons. It is the air that you breathe so, no atmosphere, no breathing. The other reason is it protects you by burning up the meteoroids that could hit earth. | In which layer of the atmosphere does our weather occur? | troposphere |
| In which layer of the atmosphere is the ozone layer? | stratosphere | What does the ozone layer protect us from? | The ozone layer protects us from the sun's powerful rays. |
| What causes wind? | The pressure gradient force, which arises from the uneven heating of earth's surface | horizontal axis | A coordinate system in which the coordinates of a point are its distances from a set of perpendicular lines that intersect at an origin, such as two lines in a plane or three in space |
