Environmental Science Concepts Assessment

The video tutorial covers Earth Day activities and AP exam preparation, focusing on Free Response Questions (FRQs). It provides instructions for confirming AP exam participation via email. The tutorial explains the design and investigation of FRQs, using examples related to the carbon cycle and environmental issues. Students are guided through analyzing environmental problems and proposing solutions, with a focus on sewage treatment and municipal solid waste management.

What is the primary purpose of responding to the College Board email mentioned in the introduction?

• To confirm your attendance at the Earth Day event

• To ensure you receive the exam link

• To update your email address

• To register for a new course

In the first type of FRQ, what are students primarily asked to do?

• Draw a graph from scratch

• Design an investigation based on a given scenario

• Create a new environmental model

• Write an essay on environmental policies

Which process in the carbon cycle removes carbon from the atmosphere?

• Sedimentation

• Respiration

• Photosynthesis

• Combustion

How does the combustion of fossil fuels affect the carbon cycle?

• It decreases atmospheric CO2 levels

• It releases ancient carbon, increasing atmospheric CO2

• It stabilizes the carbon cycle

• It has no impact on the carbon cycle

What is the effect of carbon dioxide on ocean pH?

• It has no effect on ocean pH

• It neutralizes the ocean pH

• It raises the pH, making oceans more alkaline

• It lowers the pH, making oceans more acidic

In the lab experiment discussed, what is the independent variable?

• Water temperature

• Concentration of CO2

• Amount of calcium carbonate

• pH level of the water

What is the goal of primary treatment in a sewage treatment plant?

• To remove nitrogen and phosphorus

• To disinfect the effluent

• To remove solids from the effluent

• To add chlorine to the water

What is one advantage of tertiary treatment in wastewater management?

• It increases the water temperature

• It adds nutrients to the water

• It reduces water flow

• It prevents eutrophication

How can methane emissions from landfills be reduced?

• By increasing landfill size

• By covering landfills with plastic

• By collecting and burning methane for electricity

• By reducing waste production

What is a potential environmental problem caused by raw sewage in waterways?

• Decreased water temperature

• Improved water clarity

• Eutrophication and dead zones

• Increased fish population
