2
Humans throw too many things like water bottles into the landfill.
3
How do humans contribute to solid waste pollution.
4
Industrial wastes could accidentally be released into the aquifer.
5
Why should we be careful of where we place factories?
6
Too much water flows into the stream, eroding the banks causing too much sediment to go into the river.
7
What will happen to a stream when a we pave a neighborhood with new streets?
8
Pollution from the factory drifts over
the recharge zone, when it rains the pollution flows into the recharge zone and the aquifer.
9
How can a factory affect the quality of water 20 miles away?
10
One advantage is that it is safe.
11
What are the advantages of using a model to demonstrate things like pollution.
12
5 meters X 10 Newtons
13
What is 50.0 Joules.
14
Force X Distance
15
What is the formula for work.
16
Friction
17
What is the force that causes an object to stop sliding.
18
2 meters X 6 Newtons
19
What is 12.0 Joules
20
0 meters X 50 Newtons
21
What is 0.0 Joules of work?
22
What is this river deposition feature?
The delta of a river
23
What is a river delta?
24
Erosion rounds the sharp edges into smooth curves.
25
What does erosion do to geologic features?
26
Chemical Weathering
27
What type of weathering creates caves?
28

31
What is an erosion feature of a river?
32
Not moving
33
What is stationary?
34
Groundwater
35
What is water located below the earth’s surface?
36
Plants need soil not rocks.
37
Can plants thrive on fresh rocky soil?
38
Use an inclined plane or a ramp.
39
How do you reduce the amount of force needed to move an object?
40
The amount of work cannot be reduced.
41
Can you reduce the amount of work you do in a situation?
42
The Sun.
43
What provides the energy for plants to grow?
44
Gravity.
45
What is the force that makes a plant’s roots grow down?
46
Negative geotropism.
47
A type of growth AWAY from a stimulus.
48
Phototropism.
49
What is the name for the positive growth of plants towards light?
50
Positive tropism.
51
What is the name for the tropism that pulls a plant’s roots down?
