| Question | Answer |
|---|---|
| What are the major gasses that make up the atmosphere and what percentage do they each comprise? | CO2 and nitrogen are the major gasses that make up the atmosphere. 21% 02, 78% N2, 1% everything else *need to know for quiz* |
| is carbon monoxide harmful? | carbon monoxide is harmful to the atmosphere and humans, carbon monoxide comes from fire. |
| If we have more ____than the hotter it is. | If we have more c02 than the _______ it is. |
| What are some solids or liquids that can be found suspended in this “thin layer of gases”? | Water vapor, CO2, and nitrogen can be found suspended in this “thin layer of gases”. |
| what is the main liquid in the atmosphere? | Water vapor is our main liquid in the atmosphere |
| Mesosphere - _______- Middle | Mesosphere - Meteor- _______ |
| Most meteors burn up the __________ instead of hitting the earth | Mesosphere |
| What is the coldest layer? | The mesosphere |
| What is known as the ozone layer. It is a layer made out of other tiny layers. | stratosphere |
| What layer is the closest to the earth? | Troposphere |
| Most of the mass of the atmosphere 75% is the ____________ | Most of the mass of the atmosphere 75% is the troposphere. |
| What is the thinnest layer of the atmosphere? | The troposphere |
| Warmth is radiated to the ________ | Warmth is radiated to the troposphere. |
| How does air pressure change with altitude? | Air pressure decreases as altitude increases because there's less air above you, with less weight pressing down due to gravity's weaker pull and air molecules spreading out |
| Temperatures cool as you increase in altitude in the troposphere, but in the stratosphere the opposite is true. Why? | in the stratosphere, the opposite happens because the ozone layer absorbs intense ultraviolet (UV) radiation from the Sun, converting it into heat, making it warmer higher up |
| What exactly is air pollution? | Air pollution occurs when substances harmful to life are included into the atmosphere. |
| what is a point source? | with point source pollution, the contaminants come from a single location (a point). You can literally point to it. |
| what is a nonpoint source? | nonpoint source pollution cant easily be traced back to single source it comes from many or multiple sources. |
| What is acid precipitation | burning fossil fuels, which form sulfuric and nitric acids |
| What is smog | smog forms when smoke from pollution mixes with fog |
