| Question | Answer |
|---|---|
| The Earth’s energy budget includes the solar energy ____________ and __________ Earth’s atmosphere. | Entering and exiting |
| If more energy comes into Earth’s system then goes out, the planet __________. | Warms |
| Earth’s energy budget refers to the tracking of ________________. | the balance between the amount of energy the Earth receives from the sun and the amount of energy it loses back into space. |
| Plants are able to make their own food through the process of photosynthesis due to the ________ energy. | Sun’s |
| About how much of the sun’s solar radiation is reflected back into outer space? | About 30% |
| The ______ energy is responsible for powering the motion of the atmosphere, the oceans, and many processes at Earth’s surface | Sun's |
| It is because of Earth's energy balance that we have a relatively constant ______________ on Earth. | Temperature |
| The energy absorbed in our atmosphere by ___________ and ____________ help maintain Earth's surface temperature. | Carbon dioxide and water vapor |
| If we had no atmosphere, what would happen to Earth’s temperature? | Temperature would tremendously increase in the day and decrease tremendously at night. |
| Excess ________________ and other gases affect the energy budget, creating a more intense greenhouse effect. | Carbon dioxide |
| Earth's energy budget refers to... | How much solar energy is entering and exiting Earth's atmosphere AND whether it balances. |
| What do greenhouse gases do? | They absorb heat energy and hold onto it creating a warmer temperature around our planet. |
| What would happen if we have too much of greenhouse gases added into our atmosphere due to burning fossil fuels? | It would cause the Earth's energy budget to be unbalanced. |
| What would happen if we had no greenhouse effect? | Earth would be much colder. |
| If there is an increase in greenhouse gases, what would happen to the ice caps and glaciers? | They would begin melting. |
| What is one of the main greenhouse gases? | Carbon dioxide known as CO2 |
