Part 1_Human Impacts on Groundwater & Surface Water: Understanding the Basics

Open Ended

Why is it important to understand how human activities impact groundwater and surface water in a watershed?

Multiple Choice

Which of the following is a possible effect of human activity on water resources in a watershed?

• Increased water pollution

• Improved water quality without any management

• No change in water levels

• Complete elimination of natural water cycles

Fill in the Blanks

Fill in the blank: About

% of Earth's surface is covered by water.

Multiple Choice

Why is Earth called the 'blue planet'?

• Because it has a lot of forests

• Because it has abundant liquid water

• Because it is the largest planet

• Because it is closest to the sun

Multiple Choice

Which of the following statements about freshwater is correct?

• Most freshwater is found in lakes and rivers

• Freshwater contains more than 2% salt

• Over two-thirds of Earth's freshwater is frozen

• Freshwater is not essential for life

What is runoff and how can it affect water quality?

Open Ended

Why do you think it's important to understand where runoff goes after it rains?

Multiple Choice

Which of the following best describes a stream?

• A body of water that flows within a channel

• A large body of water surrounded by land

• A flat area that collects water

• A body of water that only forms underground

Multiple Choice

How do streams interact with other bodies of water or the environment?

• They may drain into lakes or oceans

• They always end in underground caves

• They never merge with other streams

• They only evaporate

Fill in the Blanks

A lake forms when runoff flows into a

in the landscape.

Open Ended

Explain how wetlands help improve water quality.

Multiple Select

Which of the following are types of wetlands?

• Marshes

• Swamps

• Bogs

• Reservoirs

Multiple Choice

What are two main locations on Earth where ice sheets are found?

• Antarctica and Greenland

• North America and Asia

• Europe and Australia

• Africa and South America

Multiple Choice

Which of the following statements best describes glaciers?

• Glaciers are large, moving masses of ice that form on land.

• Glaciers are frozen lakes found only in Antarctica.

• Glaciers are small patches of snow on mountaintops.

• Glaciers are blocks of ice floating in the ocean.

Multiple Select

Which of the following statements about the unsaturated zone is correct?

• It contains a mix of air and water in its pores.

• It is completely filled with water.

• It is always above the water table.

• It cannot change with rainfall.

Fill in the Blanks

Fill in the blank: The water table is the

limit of the saturated zone where all pores are filled with water.

How do humans access groundwater?

Multiple Choice

Which of the following best describes the function of a well?

• A structure that allows us to access groundwater by drilling into the ground

• A device for measuring rainfall

• A type of river that flows underground

• A machine that creates groundwater

Open Ended

Explain how precipitation and drought affect groundwater levels in wells.
