1

What is one of the primary ways scientists tell the difference between a marine environment and a continental environment?

a

The speed of the water current

b

The color of the water surface

c

Salinity (how salty the water is)

2

Which aquatic environments have temperatures that change much LESS throughout the year?

a

Inland bodies of water (like lakes and rivers)

b

Oceans

c

Glaciers

3

What changes occur as you dive deeper into the ocean?

a

It becomes darker, colder, and colors gradually disappear.

b

Oxygen levels increase because of the high pressure.

c

It becomes warmer, brighter, and easier to see.

4

What is the main difference in how water moves in rivers compared to lakes and ponds?

a

Rivers flow through high areas at great speeds, while lakes and ponds are "standing" or still waters.

b

Both environments have water that does not move at all.

c

Rivers are completely still, while lakes flow at great speeds.

5

In lakes, what do living things compete for at the bottom that determines the biodiversity of that environment?

a

Sunlight and warm water.

b

Rain and sand.

c

Oxygen and remaining nutrients.

6

Which of these is a human action that deeply affects aquatic environments by changing the natural course of rivers?

a

Overfishing.

b

Building dams and canals.

c

Burning fossil fuels.

7

In Antarctica, what is the process called when glaciers wear down by touching seawater and break off into icebergs?

a

Calving

b

Eutrophication

c

Overfishing

8

What type of water pollution comes specifically from pesticides and fertilizers washed away from farming fields?

a

Industrial liquids.

b

Domestic waste.

c

Agricultural runoff.

9

During eutrophication, what do decomposers (like bacteria) do that suffocates fish and other aquatic life?

a

They freeze the lake water.

b

They consume all the oxygen in the water while eating dead plants.

c

They block all the sunlight from reaching the bottom.

10

What are the tiny plastic particles called that break down from larger plastics and contaminate the water ecosystem?

a

Nutrient runoff.

b

Floating glaciers.

c

Microplastics.
