Question | Answer |
List the major components of the water cycle. | evaporation, transpiration, condensation, precipitation |
Describe evaporation. | when water changes from a liquid to a gas |
List three types of precipitation. | rain, snow, hail |
When water rises to the atmosphere changing from gas to liquid - that is... | condensation |
Describe precipitation. | any form of water that falls to Earth from the clouds |
Where is most our freshwater found on Earth? | under ground |
Most of our drinking water is where? | under ground |
What is transpiration? | evaporation of liquids from plants |
Water that falls on the land gets to the streams, rivers , and lakes by? | runoff |
List the components of the carbon cycle. | photosynthesis, cellular respiration, decomposition, combustion |
The most abundant compound in our atmosphere is? | nitrogen |
The second most abundant compound in our atmosphere is? | oxygen |
The element of life is? | carbon |
Plants give off oxygen during…... | photosynthesis |
Animals give off carbon dioxide during... | respiration |
The breakdown of substances into simpler substances is? | decomposition |
When carbon is burned it is called? | combustion |
Where is most of nitrogen found in humans? | DNA |
The process of converting nitrogen into usable form in the soil is called? | Nitrogen fixation |
The replacement of one type of community by another at a single place over a period of time | succession |
The first organisms to live in a succession is? | pioneer species( lichen - then mosses) |
Explain the differences between primary and secondary succession. | Primary - establishing new community where none existed before; secondary - existing community is destroyed by a natural or man-made disaster. Primary succession takes much longer than secondary |

List two benefits of the water cycle. | Without water, there would be no life on Earth; it supports aquatic life forms |
List two benefits of the carbon cycle. | During photosynthesis plants use carbon dioxide to make sugars (food); humans benefit cause we use carbon products to fuel our machinery. |
