Where is majority of carbon stored?
a) atmosphere
b) soil
c) ocean
d) rocks
Ocean
Why is water important? (Name 2 ways)
Water is essential for chemical reactions.
It helps maintain cell shapes and supports cell components.
Water is a solvent, temperature buffer, metabolite, and living environment.
It facilitates the transfer of substances within cells.
All known life processes depend on water.
What is the largest impact humans are having on the carbon cycle since the industrial revolution?
What is burning fossil fuels.
Which process involves bacteria or fungi breaking down dead organisms?
What is decomposition?
Which process of the carbon cycle is likely to cause rocks to break down releasing carbon into the soil after a volcano?
Weathering of terrestrial rock
Why is nitrogen important?
Needed for photosynthesis, amino acids,proteins, and DNA
How are evaporation and transpiration similar?
How are humans impacting the nitrogen cycle?
Overuse of fertilizers, causing eutrophication
What is sedimentation?
How does deforestation impact the carbon cycle?
Deforestation prevents the removal of excess carbon in the atmosphere
Which nitrogen process occurs after an organism dies returning ammonia to the soil?
Ammonification
Which process describes water converting from a gas to a liquid forming clouds?
What is condensation?
Which of the following is NOT a way humans are negatively impacting the Phosphorus cycle?
a) Mining Phosphorus
b) Removing Phosphorus from wastewater
c) Phosphorus Fertilizer Overuse
d) Transporting Phosphorus
b) Removing Phosphorus from wastewater
bacteria that take the nitrogen in the waste of organisms and convert it back to nitrogen gas in the atmosphere
What are denitrification?
When an animal takes in food for energy in the carbon cycle, what process is performed when it releases carbon dioxide?
What is cellular respiration?
Which type of plants are needed to fix bacteria on their roots to perform nitrogen fixation?
Legumes
the loss of water from plants to the air, changing from a liquid to a gas.
What is transpiration?
How are humans impacting the water cycle? (Name 1 positive and 1 negative way)
Negative:
Agriculture
Industry
Dams
Deforestation
Positive:
Conserve water at home, in schools,and agriculture
Reduce pollution by properly disposing of waste
Protect wetlands and natural water sources
Use green infrastructure (like rain gardens) to reduce runoff
A large forest absorbs carbon dioxide from the atmosphere and stores it in trees and soil, helping reduce the effects of climate change.
carbon sequestration
A team of environmental scientists is trying to reduce the amount of carbon dioxide in the atmosphere to slow climate change. Instead of only reducing emissions, they develop a method to capture carbon dioxide from power plants and store it deep underground in rock formations for long periods of time. What process is this?
Carbon sequestration
What's special about the compound nitrogen gas?
It has 3 triple bonds that are hard to break
Because precipitation can be in the form of a liquid or solid
fertilizer runoff can cause a massive increase in algae and microorganisms in water sources that ultimately kills other organisms. This happens because the fertilizer contains a large amount of this chemical.
What is eutrophication?
Which of the following examples are NOT infiltration?
a) Runoff seeping into the soil disrupting groundwater
b) Wastewater moving downward into the sediment
c) Liquid from the surface of a lake becoming vapor
d) Surface water being pulled beneath the soil
c)
