Environmental Science: Section 2-1
Cycles of Matter
1
• water cycle
The movement of water between the oceans, atmosphere, and living things is the __________________________.
2
• Evaporation
The changing of water from liquid to vapor is called ________________________.
3
• Condensation
During _______________, water vapor cools and returns to a liquid state.
4
• Precipitation
Water that falls from the atmosphere to the land and oceans is called ___________________.
5
• 5. runoff
Precipitation that falls on land and then flows into streams, rivers, and lakes is called _________________________.
6
. groundwater
Precipitation that seeps into the ground and is stored among rocks is called ________________.
7
• 7. transpiration
Water vapor is released by plants and returned to the environment in a process called ____________________.
8
• transports nutrients• transports wastes• regulates temperature
Name three reasons water is needed for life on Earth.
9
• C : molecules that contain carbon
What are organic molecules?
10
• 10. D : by eating plants
How do animals get carbon?
11
• C : respiration
In what process is carbon returned to the environment?
12
• plants use it to make sugar
What happens to carbon dioxide during photosynthesis?
13
• fungi and bacteria break down organic matter
What happens during decomposition?
14
A substance burns
What happens during combustion?
15
• nitrogen cycle
The movement of nitrogen between the environment and living things is called the __________________.
16
• nitrogen fixation
The process in which bacteria in the soil change nitrogen gas into forms plants can use is called ____________________.
17
• to build proteins and DNA for new cells
Why do organisms need nitrogen?
18
• decomposition (bacteria and fungus)
• lightning
Name two things that perform nitrogen fixation.
19
plant roots take up nitrogen from the soil
How do plants get the nitrogen they need?
20
by eating plants or organisms that eat plants
How do animals get the nitrogen they need?
The End ….52 dead cows from one lightning strike
