Study Notes
Environmental Science Final Assessment
- The assessment covers various environmental science topics, including human population, carbon dioxide levels, acid rain, biodiversity, and more.
Human Population and Carbon Dioxide Levels
- The human population and carbon dioxide levels in the atmosphere are increasing.
Acid Rain
- Acid rain has severe effects in the northeastern United States, including New York State.
- Decreasing fossil fuel use can help reduce acid rain.
Global Warming
- Average yearly temperatures for Earth have been increasing since 1880.
- This change is likely due to increased burning of fossil fuels and increased carbon dioxide in the atmosphere.
Reducing Carbon Dioxide in the Atmosphere
- Decreasing the burning of fossil fuels can help reduce carbon dioxide in the atmosphere.
Electricity Usage
- The usage of electricity in the United States has increased dramatically over the past 10 years.
- Most of this electricity is currently produced by burning fossil fuels.
Energy Sources in the United States
- Petroleum and natural gas together provide more than 50% of the energy needs of the United States.
Groundwater Pollution
- Human activities can affect groundwater, and drinking water can become polluted from unsuspected sources.
Erosion
- Erosion is most likely when the soil is bare and exposed to wind and rain.
Industrial Revolution
- The Industrial Revolution did not directly result in the overhunting of large mammals.
Toxins in the Food Pyramid
- Toxins such as mercury can accumulate in the tissues of organisms as we go up the food pyramid.
Ecosystem Energy
- The energy in most ecosystems originally comes from green plants.
Point-Source Pollution
- Pollution that comes from a specific site is called point-source pollution.
Health Problems and Air Pollution
- Asthma is a health problem directly connected to air pollution.
Non-Renewable Energy Sources
- Oil, coal, and gas are non-renewable energy sources.
Tragedy of the Commons
- The tragedy of the commons refers to when humans overuse resources in an area.
Sustainability
- Sustainability is a condition in which human needs are met in such a way that a population can survive indefinitely.
Natural Resources
- Natural resources are living and nonliving things found on Earth that people need.
Manatees
- Manatees are mammals that live in the warm, clear water environment of Florida's shallow rivers.
- Human activities, such as habitat destruction and boat collisions, may lead to the extinction of manatees.
Biodiversity
- The loss of biodiversity is a source of concern.
- Threats to biodiversity include habitat destruction, pollution, and climate change.
- Supporting and reclaiming biodiversity can be achieved through conservation efforts and sustainable practices.
This quiz is about the impact of human activities on manatees and their habitat. Learn about the threats faced by these endangered species and how they can be protected.
