What percent of Earth's water is fresh water?

Multiple Choice

nearly two thirds of Earth's freshwater is locked up in....

• underground aquifers

• snow and ice packs in the arctic regions

• in the great lake region of the United States

• In Rivers and streams and lakes

Fill in the Blanks

Warmer ocean temperatures cause the amount of evaporation of water into the atmosphere to

(increase or decrease)

What else can cause evaporation to increase over the oceans?

What can transport water quickly from one place to another?

Multiple Select

Clouds can.... (select all that are correct)

• Insulate the earth and trap heat from the surface

• Shield the Earth from the Sun

• cause Earth to be wetter

• Make the Earth greener

Multiple Select

When water falls on land as precipitation it is then stored in (choose all that apply)

• lakes and rivers

• underground aquifers

• snow packs

• soil

When water returns to the ocean we call this process in the water cycle

use both the video and page 6 of the riverwatch guide to help with this answer

Match

Turn to page 7 and read about the different parameters we use to monitor a stream and its health. What are the 5 parameters and how do they help us monitor stream health..... Match the following

• Chemical Variables

• Habitat Structure

• Biotic Factors

• Energy Source

• Flow Regime

nutrients, alkalinity, pH, turbidity

riparian zone, depth, bank stability

disease, parasitism, predation, feeding

sunlight, nutrients, organic matter

ground water, land use, velocity

• nutrients, alkalinity, pH, turbidity

• riparian zone, depth, bank stability

• disease, parasitism, predation, feeding

• sunlight, nutrients, organic matter

• ground water, land use, velocity

Multiple Choice

If you were trying to figure out if there was a problem with biodiversity in a particular stream which parameter would be your main focus in a stream study?

• Chemical variables

• biotic factors

• energy source

• flow regime

Fill in the Blanks

Reading on page 7 of your riverwatch manual we see that habitat structure involves looking at the actual locations for living things to exist on a stream system. Those things include the width and depth of a river, the bank stability, channel morphology, gradient, instream cover, canopy, substrate, current, sinuosity, and siltation. There is one more quality not listed in this description... what did I miss?

Match

Match the following

• Habitat structure (surface area)

• chemical variable (DO)

• biological factor

• Habitat structure

  (deals with velocity and volume)

• chemical variable (BOD)

substrate

dissolved oxygen

benthic macroinvertebrates

stream flow rate

biological oxygen demand

• substrate

• dissolved oxygen

• benthic macroinvertebrates

• stream flow rate

• biological oxygen demand

We are going to explore Indiana's river systems now.... please open the next slide in a new tab so that you can toggle back and forth and answer the following questions. Take some time to explore what you see on the website link and drill down to find out if our rivers in our area are impaired, endangered, or otherwise. Learn what you can about our river system using this interactive rivers map.
