Underground Water

What occurs when used engine oil is poured into the pit in the ground?

• The oil remains sealed in the small disposal pit and does not affect the groundwater.

• The oil seeps through the soil until it leaks into the groundwater

• The oil seeps through the soil but stops before it reaches the groundwater

• The oil creates a barrier in Mrs. Dyess' room

What is the effect of used engine oil that is poured into the pit in the ground?

• The oil will insert chemicals into the groundwater

• The oil will not affect the groundwater

• The oil will purify the groundwater

• The oil blows bubbles when you swim in it.

What will occur as a result of garbage being placed on the surface of the old dump?

• The groundwater under the dump will dry up

• The groundwater under the dump will become polluted

• The groundwater under the dump will reverse direction

• The garbage will become fun to swim with.

Fertilizer can seep through the ground to reach groundwater, what effect can it have?

• Fertilizer can cause groundwater to reverse flow

• Fertilizer can cause groundwater to freeze

• Fertilizer can cause groundwater to become undrinkable

• It will seep into the school

The photo shows rusting barrels floating in shallow river water. How will the rusting barrels in this stream affect the surface water in the watershed?

• The barrels will alter the course of the surface water that reaches the river.

• The barrels will not affect the surface water that reaches the river.

• The barrels will pollute the surface water that reaches the river.

• The barrels will be fun for Mrs. Glaesmann to ride down the river.

What will happen if local groundwater makes contact with the barrels in this stream?

• The groundwater will become less clean

• The groundwater will not be affected

• The groundwater will react by flowing back under the ground

• You can drink the water.

When an area is experiencing drought, humans may excessively pump groundwater out of aquifers. All of the following are effects of this excessive pumping EXCEPT -

• soil collapsing

• Dotties waterbowl

• water quality decreasing

• groundwater depleting

The runoff will affect local watersheds in all of the following ways EXCEPT-

• by increasing sediments in the stream

• by contaminating the lake with heavy metals

• by introducing acid rock drainage to the lake and stream

• by increasing the number of animals that live in the lake or stream.

Which of the following is the most likely cause of algal bloom?

• Humans dumped their trash directly into the pond, causing the water to become unclean

• A seasonal algal cycle caused the water to have too many organisms living in it

• Fertilizers from nearby fields drained into the pond, causing an excess of nutrients

• Acid rain transported pollution from nearby bodies of water through the water cycle.

Which of the following organisms do NOT benefit from the runoff?

• Fish, swimming near the shore of the beach

• Humans, using the fertilizer to produce more crops

• Crop plants, getting nutrients that normall wash out of the soil

• Glaesmann, the microscopic organisms that cause the red tide.
