1. wave base The depth below the surface where the circular
orbits become so small that movement is neg-
ligible. It is equal to one-half the wavelength
2. what happens when waves "feel bottom" when waves feel bottom, their speed and
wavelength decreases while their height and
steepness increases
3. How does sand move on the beach? Perpendicular to shoreline (toward and away),
swash and backwash, Which ever dominates
determines whether sand is deposited or
eroded from the berm
4. wave refraction the bending of waves so that they move nearly
parallel to the shoreline
5. what causes wave refraction changes in wave velocity due to rock density
differences
6. What are typical features of an emergent High cliffs, steep slopes, exposed bedrock
coastline?
7. What are features typical of a submer- Lagoons, bays, tidal flats
gent coastline?
8. What do barrier islands represent? The building of sediment in which wave and
tidal action move parallel to the mainland
coast
9. What is the cause for most modern estu- As glaciers receded and melted, sea levels rose
aries? and inundated low-lying river valleys
10. What is the cause of Earth's tides? The moon, as the moons gravity pulls the
waves this creates high tide and low tide

11. subtidal zone area where the seabed is below the lowest tid
12. supertidal zone top of highest tide to the landward edge of
coast
13. interridal zone the area of shoreline between low and high
tides
14. fetch area in which ocean waves are generated by
the wind
15. littoral zone a shallow zone in a freshwater habitat where
light reaches the bottom and nurtures plants
16. How can you recognize desert sediments Cross-bedding, ripple marks, and lack of fos-
and environments in the rock record? sils, iron oxide
17. Describe the primary wind-sourced de- Sand dunes, Loess' and dust
posits?
18. What are the typical dune shapes? Why -Crescentic, linear, star, dome, and parabolic
their particular shape?
19. Desert and steppe lands cover about 30%
what percentage of Earth's land area?
20. Saltation transportation of sediment through a series of
leaps or bounces
21. What will effectively limit further defla- Desert Pavement
tion in a given area?
22. What determines the angle of repose for the direction in which the wind is blowing
dry sand?

23. A dune migrates in the direction of incli- slip face
nation of the________?
24. Why are glacial valleys u-shaped? Usually glaciers will start where a river was
cutting a V-shaped valley, and the glaciers then
erode the sides of the valley into a U-shaped
valley.
25. Cirque a half-open steep-sided hollow at the head
of a valley or on a mountainside, formed by
glacial erosion. circular
26. Moraine a mass of rocks and sediment carried down
and deposited by a glacier, typically as ridges
at its edges or extremity.
27. terminal moraine a moraine deposited at the point of furthest
advance of a glacier or ice sheet.
28. medial moraine A moraine formed when two advancing valley
glaciers come together to form a single ice
stream, forms in the middle of the glacier
29. lateral moraine moraine that forms along the side of a glacier
30. What is important about a terminal Helps show how fast and where certain glaci-
moraine? ers flowed
31. What is an outwash plain? A plain formed of glacial sediment deposited
by meltwater outwash at the terminus of a
glacier.
32. How/why does a outwash plain form?
