Living and nonliving things such as plants, animals, air, and dirt.
Where can nitrogen be found on earth?
100
Lakes, streams, runoff, ground.
What does water go when it rains?
200
Higher transparency means healthier river
What Transparency is healthy for a river
200
Through food chains, the carbon that is in plants moves to the animals that eat them
How is carbon transferred to animals?
200
This also is the same as the number of protons and electrons.
What is Atomic number
200
They need it to make amino acids, proteins, and plants.
What do plants and animals need nitrogen for?
200
Solid-snow
Liquid-rain
Gas-Dew
What are three phases of matter and examples within the water cycle.
300
The volume of water that moves through a river over a given period of time
What is Stream flow
300
When you inhale you release carbon. People burn fossil fuels to power factories, power plants, cars, and trucks.
How do humans impact the carbon cycle?
300
A variation of an atom that has a different mass due to neutrons being gained or lost.
What is an Isotope
300
From eating plants or other animals that contain nitrogen.
How do animals get the nitrogen they need to survive?
300
A place where water forms and eventually becomes a stream. They contribute to lakes, oceans, and other steams.
What is Runoff
400
Water that moves through the surface of the land into a low area and can cause stream flow to increase.
What is Runoff
400
Keeps earth from losing all the heat it absorbed during the day each night.
What is the greenhouse effect
400
Columns of elements
What are groups
400
By using too much nitrogen, it might get to streams or rivers making them have too-much nitrogen.
How do humans affect (change) the nitrogen cycle.
400
It can pollute lakes and rivers. If the precipitation is intense and/or the soil is saturated, flooding can occur.
What are side affects of runoff.
500
soil erosion as runoff carries loose soil with it, construction sites and plowed fields are common sources of soil erosion, and waste water discharge from storm sewers or sewage treatment plants.
What are sources of cloudy water?
500
Process that moves carbon dioxide from high to low concentrations
What is diffusion
500
It shares both the same properties as metals and nonmetals. Can be shiny or dull, it is a solid, and conduct some heat but not as good as metals.
What are Metalloids
500
Areas of the ocean where animals can not survive. Air pullutants that contain nitrogen decreasing air quality and greenhouse gases. It is an oxygen-depluted water in which nothing can survive.
What are dead zones?
500
The bigger the soil is, the bigger more space it has to store water.
