1) The two conditions in which nitrogen will react to with oxygen are under high temperature and pressure
2) Two compounds in which nitrogen combine with oxygen are nitric oxide and nitrogen dioxide.
3) Nitric acid forms when nitrogen dioxide combines with rain water.
4) Nitric acid is important so that plants can have nutrients
5) 79% of he air we breath is nitrogen
6) Some plants don't use the nitrogen in the air because the nitrogen they need needs to be in fixed form.
7) The compounds plants use are NO3, NH4+, (NH2)2CO.
8) Animals get the nitrogen they need from the plants they eat.
9) a) atmospheric fixation is when lightning breaks nitrogen molecuels making them be able to combine with oxygen.
b) industrial fixation is when its under pressure like 600* C and with catalyst, atmospheric nitrogen and hydrogen
they form ammonia.
c) biological fixation is when only certain bacteria and archaea can fix nitrogen, the plants associated with symbiotic
relationships are the legume family.

10) Nitrogen is needed by plants and animals because they use the molecules to make complex organic molecules like amino acids and proteins.
11) Water Cycle is a process in which it gives us water to drink, fish to eat, and help us grow crops.
12) About 97% of the earths surface is covered in water.
13) Only 1% of the earths water is usable to humans and land animals.
14) Evaporation is the process where a liquid changes form its liquid state to a gaseous state.
15) Evaporated water is so clean because during the whole process the impurities are left behind leaving it cleaner.
16) Condensation occurs when a gas is changed into a liquid.
17) Condensation is the opposite of evaporation.
18) When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs.
19) Transpiration is when plants absorb water from the soil the water goes form the roots through the stem to the leaves.
20) Percolation is the filtering of fluids through certain materials.
21) The water cycle is when the ocean water evaporates into the air and condenses into clouds, then precipitation comes and the water falls back to the ocean so that it can be evaporated again.
22) The factor that determines if its solid liquid or gas is the temperature.
23) The water on earth is constant there is as much water now as there was along time ago.
