Flashcards in CH11 Deck (14):
1

Waves

generated by surface winds, and transfer energy one place in the ocean to another; this energy is eventually expressed in the form of erosion when a wave meets a shoreline

2

Wave refraction

Waves refracted (bent) as they approach shoreline

3

Headland

Land, possibly containing cliffs, that projects into the ocean

4

Sea Arch

A headland that has been cut by erosion into an arch

5

Sea Stack

An isolated rock formation that resembles a tiny island left from the collapse and erosion of surrounding rocks

6

Tambolo

A ridge of sand that connects a sea stack or small island to the mainland or to another island

7

Wave-cut Platform

A flat bedrock surface along a shore that is cut by wave erosion

8

Spit

An elongated ridge of sand that projects from the land into the mouth of an adjacent bay

9

Baymouth Bar

A bar that extends the mouth of a bay

10

Currents

a flow of water and energy caused by wind, water density, water temperature differences

11

Currents

Surface-­‐Ocean Currents and Deep-­‐Ocean Circulation.

12

Density determined

by salinity( mainly controlled by evaporation and precipitation ) and temperature (greatest effect). Cold seawater with high salinity is densest.

13

Deep water circulation

begins in highest latitudes where water is densest

14

Tide

The daily rise and fall of sea level caused by the gravitational attraction of the Moon
