What are the three phases of water?

Ice, liquid, water

Solid, ice, water vapor

Water vapor, liquid, gas

Ice, water, water vapor

1

What is true about macroinvertebrates?

They are animals with no backbone that are visible to the naked eye

They are categorized into three groups by how they react to pollution: very sensitive, somewhat sensitive, and tolerant

You can tell long term health of a stream by looking at them

All of the above

1

Water can NOT get directly back into the ocean by:

Underground flow

Surface run-off

Precipitation

Infiltration

1

What happens to the water molecules as they get below 4°C?

The water molecules expand

The water molecules condense and get denser

The water molecules get less dense and float

Both A and C

4

Match the following types of living organisms with the correct definition.

Draggable item		Corresponding Item
Nekton		On the bottom sands or in the sands; clam

Neuston		Floating in the water column; phyto or zoo___
Plankton		Free swimming; fish

What is a floodplain?

An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding

An area on the continental shelf that gets covered with water during low tide.

A reservoir to collect rain water.

A populated area that was devastated by a flood.

1

Water combines with carbon dioxide in the air or water to produce carbonic acid causing ocean acidification.

True

False

1

When a polar molecule, like soap or salt, is added to water, the:

Surface organisms will sink

Polar molecules will mix in all the water

Some surface organisms will sink and some will float

Both A and B

1

Choose the statement that is TRUE.

Sublimation is the process sweat goes through when it is evaporating

Sublimation can be found in aquifers as the rain infiltrates through the soils

Sublimation can occur from snow-covered mountains and glaciers

None of these are true

4

Match the appropriate word for the amounts of each found on Earth.

Draggable item		Corresponding Item
D		Land
A		Water
B		Fresh water
C		Salt water

1

What divides a watershed or drainage basin?

The watershed or drainage basin is divided by the person who owns the property

The watershed or drainage basin divide is created by where the river flows

The divide is created by the highest points of land surrounding the watershed or drainage basin

The divide is created by the political government in which the watershed or drainage basin is found.

1

Salinity of seawater increases

As evaporation increases

Around ice as ice melts in spring

Near the mouth of rivers

With an increase in rain

1

In a natural area/country, what percent of precipitation infiltrates into the ground?

25%

50%

75%

85%

1

Water molecules are constantly breaking bonds with other water molecules and re-bonding.

True

False

1

What happens to pollution in a watershed?

It stays in the same place

It washes into the nearest stream

It can pollute things downstream

Both B and C

1

What makes up a watershed?

Climate and amount of rainfall

Geology of the land (hills, valleys)

Man-made geography

All of the above

1

Cold water fish have different oxygen requirements than warm water fish. What would happen if you put a cold-water fish into a warm water tank.

Nothing – they are tough enough to survive with the extra oxygen

They would die from too much oxygen

They would die from not enough oxygen.

None of the above

1

What happens to a non-polar molecule when it is added to water?

It can float on the top

It mixes evenly with the water

It breaks apart into individual atoms and attaches to the water molecules

Both A and C

1

Water in nature has a neutral pH of 7.

True

False

1

Salinity of seawater decreases

As evaporation increases

Around ice as it melts in spring

Near the mouth of rivers

Both B and C

1

Why can water have no net charge but have slight charges in different parts of the molecule?

The oxygen end is slightly negative and the hydrogen end is slightly positive

The hydrogen end is slightly negative and the oxygen end is slightly positive

The hydrogen and oxygen ends change in polarity

Because it is neutrally charged.

1

What would happen if ice in had a higher density than liquid water?

Nothing, It already does

Ice would sink

Ponds and lakes would freeze solid

Both B and C

1

Which of the following will NOT help you to conserve water in your watershed?

Turn off water when you brush your teeth of soap your hands

Wash your car on the driveway

Plant native plants that do not require as much water

Wash only full loads of dishes or clothes

2

Which is a gaining stream and which is a losing stream?

Draggable item		Corresponding Item
B		Losing stream
A		Gaining stream

4

Use the diagram below to lable the ocean zones

Draggable item		Corresponding Item
4		Neritic
3		Oceanic
1		Photic
2		Aphotic

1

Which statement is FALSE about the water and density?

Warmer water is less dense and floats; colder water is denser and sinks.

Fresh water is less dense and floats; salt water is denser and sinks.

Water in an 8‰ (salinity) sea is less dense and floats while water in a 40‰ (Salinity) sea is denser and sinks.

None of the above are false

1

Which statements are true about freezing and boiling points of water?

Water freezes at 32°F and 0°C

Water boils at 212°F and 100°C

Both A and B are true

Both A and B are false

1
