Environmental Studies-Review for 2nd Semester Final

During a field trip, Mason, Abigail, and Noah observed the presence of wastes, such as plastic bags, chemicals, oil bottles, in a remote lake. This suggests that ____________

• ecosystems are interconnected and human action can negatively impact the balance of the environment.

• recycling programs have failed to conserve biotic resources.

• natural processes can alter ecosystem stability.

• direct harvesting of practices have led to irreversible destruction of ecosystems.

During a school field trip, David noticed water from rain or melting snow flowing over the surface of the ground into streams. (a)  

• Slush

• Acid Rain

• Rainwater

• Runoff

Steve wants to know which soil is best to plant tomatoes in. Which of the following experiments can he complete in order to answer his question.

• Plant each seed in each type of soil.

• Compare the color of the soil to the soil chart.

• Pour 200 mL of water into each soil to see how much water is retained.

• Wet the soil and feel the texture.

Abigail is studying environmental science and is curious about soil formation. She asks, 'How long can it take to form a centimeter of soil in a natural setting?'

• 0-50 yrs

• 50-100 years

• 100s-1000's of years

• 10,000-100,000s of years

While studying the Mississippi River watershed for a school project, Samuel asked, 'What describes the smaller streams and rivers that feed into the larger river of a watershed?'

• Lake

• Tributary

• Estuary

• Drainage Ditches

Why is soil an important natural resource in Jackson's farm?

• Soil is used to make buildings.

• Soil comes from bedrock.

• Soil can grow crops.

• Soil is full of microbes.

During a school project, Mason, Michael, and Jackson are discussing soil composition. Mason asks, 'What is one thing that soil is not made of?'

• air and water

• dead plants and animals

• weathered rocks and minerals

• cement and asphalt

In a rainforest ecosystem, the unique role the hummingbird species plays, such as pollinating specific types of flowers, is known as its _________

• niche

• nook

• habitat

• relationship

During a school project on natural processes, Aria, David, and Abigail are discussing how soils are formed. Which of the following explanations did they find to be the most accurate?

• As plants and animals break down, the carbon in their bodies turns into minerals that plants eat in order to survive.

• As animals consume plants, they convert the plant matter into minerals. The feces from the animals then forms the soil.

• Over thousands of years, rocks are weathered down to small particles that mix with small amounts of decaying organic matter and living organisms.

• Over thousands of years, carbon dioxide in the air converts into minerals that fall to the ground and form soil.

During a field trip, Aria, Harper, and Scarlett observe a rural forested area that receives a lot of rain in a short amount of time. What would most likely cause potential flooding in the area?

• If the ground of the area is already saturated with water.

• If the area has a large uncharged aquifer beneath it.

• If the water level in the area is below the non of saturation.

• If the ground of the area is mostly sandy soil.
