Section 2 - Question Set 4

Question 1

Alluvium

Answer 1

General term for stream deposited materials

Question 2

Alluvial Fan

Answer 2

Triangular-shaped accumulations of deposits

Question 3

Delta

Answer 3

Built out onto the quieter water of a lake or bay by debris brought down from areas of
heavy erosion

Question 4

Arroyo

Answer 4

Streams erode valleys with steep, vertical walls and wide debris-choked floors

Question 5

Barrier Beaches

Answer 5

Are built up along shallow coasts some distance from the shoreline.
Example: Miami Beach. Under conditions of prolonged erosion and rising sea levels, barrier beaches can be shifted shoreward from the overwash of storm waves and the backshore deposition

Question 6

Beach Ridges

Answer 6

Berms built up by waves - erosion and deposition

Question 7

Cuestas

Answer 7

Gently sloping ridges bounded on one edge by an escarpment. Changes in rock
types are reflected in the development of cue

Question 8

Basin and Range Topography

Answer 8

Smaller block fault ranges, ten miles or so wise, separately
alluvium-filled basins, as in Nevada and Utah

Question 9

Cuspate Bars

Answer 9

• Roughly triangular shape slope resulting from two sand bars building out from
  the shore In opposing direction and forming a point, as In Cape Canaveral

Question 10

Drumlin

Answer 10

Glacial debris; overridden by moving ice and shaped into teardrop-shaped landforms;
long axis of drumlin parallel to direction of ice flow

Question 11

GROUND MORAINE

Answer 11

• deposited beneath glacier

- makes flat landscape

Question 12

Knob and Kettle Topography

Answer 12

Local relief is not high; one sees small hills, ridges and saddles 
and kettleholes (can be lakes) and short Irregular slopes

Question 13

Kame

Answer 13

depositional feature of glaciation; a small hill of poorly sorted sand and gravel that accumulates in crevasses or in ice, causes indentation in surface

Question 14

Esker

Answer 14

long winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America

Question 15

Till

Answer 15

Till are glacial deposits of rock that are angular and unsorted, with the long axes orientated in the direction of glacier flow.

Question 16

Plain

Answer 16

A plain is an area of land that is mostly flat with gentle slopes, is a low elevation underlain by flat lying rocks.

Question 17

Lake Terrace

Answer 17

movement of water by wind - deposition of material

Question 18

Spit

Answer 18

Excess of sand from shore drifting extends a beach laterally out into the water

Question 19

Outwash Plain

Answer 19

Smooth, broad, gently sloping plain, similar to coalescing alluvial fans; heavily-
loaded streams of meltwater, braided channels help to form outwash plains.

Question 20

Pediment

Answer 20

Slightly sloping, broad, rock-floored eroslonal surfaces that typicaily develop in desert regions at the base of a receding mountain front

Question 21

Zoning

Two types of zoning procedures:

Answer 21

Zoning Code or Text Amendments - public
hearings required
Map Amendments or Rezoning - public
hearing required

BASIC PROCESS:

• recommendations by Planning Commission
• Final Decision by City Council (Governing body)
