WEEK 2 -
TOPO MAPS
Using Map 7-7 on page 143 of your lab manual, draw a topographic
profile along the line A-A' . Use a vertical scale of one inch = 100 feet.
- draw the profile once using only the index contours
- draw the profile again using all the contour lines
- What is the advantage to using all the contour lines
as oppossed to only the index contours?
- In your own words, describe the topography.
WEEK 3 -
PLATE TECTONICS
- Complete the exercise "Earthquakes in the News"
handed out in lab.
- You may want to go to the map room on the 2nd floor of
the SCE Library.
WEEK 4 -
MINERALS
- Read Chapter 2 over Igneous rocks in yur lab manual.
- Complete Ex. 2-1 and Ex. 2-5 question 1 ONLY.
WEEK 5 -
IGNEOUS ROCKS
- Read Chapter 3 over Sedimentary
rocks in your lab manual.
- Complete Ex. 3-6 question 3
ONLY.
FOR QUESTION 3 (Hjulstrom Diagram)
- The Hjulstrom diagram is useful
for determining the water velocity required to carry a certain sediment
size in suspension. For example, for a grain size of 50mm (pebble size),
the velocity required to keep it in suspension must be greater than 500
cm/s. If the velocity drops below 500 cm/s the particle will be dropped
and deposited. In this case, 500 cm/s is the velocity cut-off between erosion
and deposition.
- the exercise is to determine the
velocity cut-off values for the 4 main grain sizes according to the Wentworth-Udden
grain size scale on p. 45.
- grain size >2 mm >>>
GRAVEL
- 0.063 mm < grain size < 2
mm >>> SAND
- grain size < 0.063 >>>SILTS
andCLAYS
- Now, what are the corresponding
velocity cut-off values for each grain size according to the Hjulstrom
diagram?
- On the map of the river mouth,
draw contour lines which correspond to the velocity cut-off values and
shade the areas between the contours according to grain size, i.e every
thing between these contours is gravel, between these is sand etc.
- Complete Ex. 7-13 questions
1, 2, and 3 ONLY
FOR QUESTION 1 (PROFILE)
- for vertical scale use:
- maximum elevation = 12,000 ft
- minimum elevation = 2,000 ft
- watch the contours when you get
to the lake, the blue lines are depths below the base lake water level.
Base lake water level is the elevation of the last contour on the edge
of the lake. To determine the elevations of points on the bottom of the
lake (which you need to draw the profile), just subtract the depth below
water level from the base lake level.
FOR QUESTION 3 (CALCULATE VOLUME)
- the formula for calculating the
volume of a cone should be :
- V = (3.14*radius^2*height)/3.
- Don't forget to divide by three,
the formula in the manual is wrong!
