What is the largest impact humans are having on the carbon cycle since the industrial revolution?

What is burning fossil fuels.

100

Which process involves bacteria or fungi breaking down dead organisms?

What is decomposition?

200

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

200

Why is nitrogen important?

Needed for photosynthesis, amino acids,proteins, and DNA

200

How are evaporation and transpiration similar?

Both processes involve the conversion of liquid to a gas
200

How are humans impacting the nitrogen cycle?

Overuse of fertilizers, causing eutrophication

200
Nutrients settling at the bottom of a river forming layers over time.

What is sedimentation?

300

How does deforestation impact the carbon cycle?


Deforestation prevents the removal of excess carbon in the atmosphere

300

Which nitrogen process occurs after an organism dies returning ammonia to the soil?

Ammonification

300

Which process describes water converting from a gas to a liquid forming clouds?

What is condensation?

300

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

300

bacteria that take the nitrogen in the waste of organisms and convert it back to nitrogen gas in the atmosphere

What are denitrification?

400

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?

400

Which type of plants are needed to fix bacteria on their roots to perform nitrogen fixation?

Legumes

400

the loss of water from plants to the air, changing from a liquid to a gas.

What is transpiration?

400

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

400

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

500

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

500

What's special about the compound nitrogen gas?

It has 3 triple bonds that are hard to break

500
Why is precipitation not considered a conversion of gas to a liquid?

Because precipitation can be in the form of a liquid or solid

500

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?

500

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)
