The three types of rocks are:
What are sedimentary, metamorphic, and igneous?
100
Rocks are classified based on their:
What is method of formation?
100
This organism is involved with nitrogen fixation:
What is bacteria?
100
Humans fixate nitrogen by:
What is applying fertilizer?
100
Define biogeochemical cycle:
What is a cycle in which chemicals move through the biosphere (living organisms) and geosphere (Earth)?
200
Metamorphic rocks are formed by:
What is heat and pressure?
200
Convection cells involve the movement of this in a cyclical manner:
What is the movement of warm (towards top) and cool (towards bottom) fluid material in a cyclical manner?
200
Nitrogen fixation is:
What is the process by which nitrogen is converted into useable forms?
200
Nitrogen is added to our environment in this way: (more than one correct answer)
What is agriculture/fertilizer, sewage, etc.?
200
Nitrogen composes this percentage of air:
What is 78%? (will take +/- 1%)
300
Igneous rocks are formed by:
What is melting and cooling?
300
These two environmental factors are most responsible for weathering and erosion:
What is wind and water?
300
This natural phenomena fixates nitrogen.
What is lightning?
300
Describe the relationship between sewage and the nitrogen cycle:
What is that humans excrete nitrogen in the form of human waste and this is sewage?
300
The rock cycle and nitrogen cycle are connected through:
What is soil? Rocks erode to create soil (along with decaying organic matter) and soil also stores nitrogen. Answers can vary.
400
Sedimentary rocks are formed by:
What is What is weathering and eroding, then compaction (pressure)?
400
Define metamorphism (include what 2 things change the rock):
What is change due to intense heat and pressure?
400
Animals gain and lose nitrogen by:
What is eating and excreting (going to the bathroom)?
400
Name three reasons why humans should care about the nitrogen cycle:
What is because it adds to water pollution, acid rain, climate change, air pollution, and acidification of soil?
400
The rock and nitrogen cycles are both considered cycles because:
What is because sediments (for rock) or nitrogen move through the cycles in no particular order and can constantly switch forms?
500
Marble is this type of rock.
What is metamorphic rock?
500
The relationship between convection cells and the rock cycle is:
What is rocks that move towards the center of the earth are changed into magma and then can be converted into various forms?
500
Some "stations" during the nitrogen cycle activity were more popular than others because:
What is because certain "places" of the cycle are generally more popular than others?
500
When too much nitrogen gets into the water, the following can happen:
What is an oxygen dead zone is created and fish die?
