Group Test – Weathering and Erosion 2014
1. Define the following vocabulary words:
Weathering
Erosion
Deposition
Delta
Sediment
Mean
Median
Mode
2. What does a topographical map show?
a. cities and towns
c. changes in elevation, the shape of the land
b. what kind of habitat is in an area
d. political divisions (states, etc.)
Use the following hypothesis to answer questions 3-6
If two groups of fish (all the same species, age, and size on day one) are raised with
different types of food, one with a high amount of protein and the other with a low amount of
protein, then the fish that eat high-protein food will grow longer on average than those that eat
low-protein food, because protein is important for growing muscles and other types of cells.
3. Identify the independent/manipulated variable
4. Identify the dependent/responding variable
5. Three controlled variables are given in the hypothesis: the species, age, and size
on day one. What are two other variables you, the scientist, would want to control
for this experiment?
6. Draw two topographical maps that have the same contour intervals and scales.
The first topographical map shows a hill that has an elevation of 100 meters, is
steep on the west side, and less steep on the east side. The second topographical
map shows a valley running from the southeast to the northwest, with steep banks
that rise 100 meters above the valley floor.
7. Set up the data table below so that it will hold four weeks' worth of average fish
length data. Be sure to write a title for the table.

8. The following is ‘Average Monthly Rainfall’ data for Seattle, Washington.
Calculate the mean, median, and mode of the data (show your work). Then
construct a bar graph using the grid on the next page for the data, putting the
“Month” on the horizontal axis and “Rainfall in inches” on the vertical axis.
