How does rain/runoff affect the transparency of a river?

It kicks up sediment.

100

How would a drought affect stream flow?

There would be less water in the river.

100

How could a higher temperature affect the amount of dissolved oxygen in a river

Higher temperatures decreases the amount of dissolved oxygen.

100

Would fertilizer use increase or decrease nitrate levels?

It would increase nitrate levels.

100

What is the universal law of gravitation?

The bigger the object the more things are attracted to it.

200

How does construction affect the transparency of a river?

It creates lose dirt.

200

How would rain/runoff affect stream flow?

There would be more water in the river.

200

How could a lower temperature affect the amount of dissolved oxygen in a river?

Lower temperatures means it increases.

200

Would dumping human/animal waste into a river increase or decrease nitrate levels?

They would increase.

200

What 2 variables affect gravitational force?

Mass and distance.

300

How does agriculture/farming affect the transparency of a river?

Also creates lose dirt.

300

How could humans affect stream flow?

The agricultural business and irrigation.

300

In general, is it better for dissolved oxygen levels to be higher or lower?

Higher

300

Would a higher plant population increase or decrease nitrate levels?

They would decrease.
300

Which variable of gravity does NOT change?

Gravity.

400

How would a drought affect the transparency of a river?

It wouldn’t.

400

How could seasons affect stream flow?

The summer time decreases the amount of water in the river while in the spring it increases.

400

What is the dissolved oxygen standard for Vermillion River trout?

7 mg/L

400

Is a higher or lower nitrate level better?

A lower level is better.

400

if an object is at rest it will stay at rest, which makes its velocity what?

Zero.

500

Is it better for a river to have a high or low transparency?

Higher is better.

500

Is it better for a river to have a higher or lower flow?

Bit of both.

500

Is it better for a lake to have more or less dissolved oxygen?

Higher is better.

500

What is the standard level of nitrates for Vermillion River trout?

10 mg/L

500

What is inertia?

The property of an object to resist any change in motion.
