STUDY GUIDE PART 2
This guide contains in an outline/question format the important points that we have covered in
the course, you will be expected to have an understanding of this material for an exam
Hydrologic Cycle and River Systems - Chapters 2, 16, & 17
in
Exploring Geology
Know the relative distribution of water on the Earth
Oceans - 97%
Glaciers and Polar Ice - 2%
Underground aquifers - 0.5%
Lakes and Rivers - 0.02%
Atmosphere - 0.0001%
Biosphere - 0.00004%
Understand the hydrologic cycle (see section 17.1)
What are the main parts of the cycle?
eg. evaporation, precipitation, runoff,
groundwater, and transpiration
What is a drainage basin?
a drainage divide?
Note: that watershed is a term that is now more
commonly used to describe a drainage basin.
Know the five patterns of river drainage and the geologic setting in which they occur
1) dendritic
2) rectangular
3) trellis
4) radial
5) distributary
What is a longituidinal profile?
How does the longituidinal profile of a river or stream
change from its headwaters to its mouth?
What is discharge?
How is discharge related to channel width, channel depth, channel
shape, and water velocity?
Know that the velocity of a stream is dependent upon both discharge and the stream gradient
What are the typical downstream changes in discharge, stream gradient, and velocity?
