Chapter 19: Cycles
| Question | Answer |
|---|---|
| Precipitation that falls on land and flows into bodies of water | Run off |
| The change of water from a liquid to a vapor is: | evaporation |
| Where is freshwater “locked” away so that it is not easily accessible? | Glaciers and Icecaps |
| The process by which plants take in Carbon Dioxide (CO2) and use sunlight to make energy is: | Photosynthesis |
| The breakdown of organic material by burning to release Carbon Dioxide (CO2) into the atmosphere | Combustion |
| How do animals get the carbon ? | By eating plants |
| What do all organic material contain? | carbon |
| Earth’s supply of FRESHWATER is renewed by: | Precipitation |
| The process by which organisms breakdown dead or dying material and return carbon into the atmosphere: | Decomposition |
| Why is the carbon cycle important to living things? | It transports a material needed by all living things. |
| When plants return water to the environment it is called | Transpiration |
| Name one reason why all organisms need carbon | To make new cells and rebuild DNA |
| When water changes from a vapor (gas) to a liquid? | Condensation |
| Precipitation seeped into the ground and stored in spaces between rocks | Ground water |
| The process by which sugar is broken down to release energy, uses oxygen | Respiration |
| The process by which plants use carbon dioxide from the air to make sugars (glucose) | Photosynthesis |
| When we burn fossil fuels for our homes, what is released into the atmosphere | Carbon dioxide |
| Matter is never created or: ________________________ | Destroyed |
| Wind, sun, and water are considered | Renewable resources |
| Fossil fuels | Nonrenewable resources |
| This was created from the remains of dead plant life that was compressed by soil, sediment, and rocks over millions of years. | Coal |
| Human release what gas into the atmosphere through respiration | Carbon dioxide |
| Plants release this molecule into the atmosphere by the process of photosynthesis | oxygen |
| 3 examples of nonrenewable resources | Oil, natural gas, and coal |
| 3 examples of renewable resources | Wind, sun, and water |
| 3 ways that water is can be cycled through the carbon cycle | Condensation, precipitation, evaporation |
| 3 ways that carbon dioxide can be added to the atmosphere | Volcanic eruptions, car emissions, and burning of coal |
| 3 ways the water cycle's balance can be effected | Pollution, drought, lack of plants |
| 3 ways the humans can effect the carbon cycle's balance | Pollution, consumption/burning of fossil fuels, deforestation (cutting down forests) |
