25
Deepest point of the ocean
Mariana Trench
26
Depth of Mariana trench
36,198 feet
27
Study of oceans
Oceanology
28
Found along most of coastal areas
Passive continental
29
Continental shelf has the total ocean area
7.5%
30
Slope dropped to about 6 meters
Continental rise
31
Steep structure that mark the boundary between continental crust and oceanic crust
Continental Slope
32
-Gently sloping submerged surface
Continental shelf
33
-has political and economic significance because it contains mineral deposits that include large deposits of petroleum
Continental shelf
34
Thick accumulation of sediments
Continental rise
35
-Extend for hundreds of kilometers into deep ocean basin
Continental rise
36
Sediments from the ocean floor and pieces of oceanic crust are scraped
Active Continental Margins
37
Continental slope merges into a more gradual line
Continental rise
38
This is technically active where earthquakes and many volcanoes are highly active
Active Continental Margins
39
5 types of continental margins
•Passive continental •continental shelf •continental slope •continental rise •active continental margins
40
Flat features and regions that are likely the most level place on earth
Abyssal Plains
41
Downslope movements of dense, sediment-laden matter
Turbidity Currents
42
Created when sand and mud on the continental shelf and slope
Laden water
43
Volcanic peaks that dotted the ocean floor
Seamounts
44
Can rise hundreds of meters above the surrounding topography
Seamounts
45
Long, relatively narrow features that form the deepest parts of the ocean
Deep ocean Trench
46
-Moving lithospheric plates plunge back into the mantle -located in Pacific ocean -earthquake and volcanic activity are highly associates with
Deep ocean trench
47
Generates on surface currents
Wind
48
Carry the energy from storms to distant shores
Waves
49
Produces tides and density differences create deep ocean circulation
GRAVITY of the moon
50
Time required for the wave crest
Wave period
51
Number of wave crest
Wave frequency
52
3 kinds of deep ocean basin
•abyssal plain •deep ocean trench •seamounts
53
Types of waves
•Waves of oscillation •waves of translation
54
Turbulent advance of water formed near the shore as waves of oscillation
Waves of translation
55
In the open sea form advances as the water particles move in circular orbits
Waves of oscillation
56
Made different salts, sulfates and carbonates
Sea
57
Commonly small, shallow, and near the continental areas or land
Seas
58
Lesser amount of salts compared to ocean
Sea
59
9 seas of the world
•Red sea •caribbean sea •mediterranean sea •andaman sea •beriing sea •okhotsk sea •japan sea •baltic sea •china sea
60
Large, natural stream flowing water. Found in every continent and on nearly every kind of land
River
61
It could be short and long, wide and narrow
River
62
5 river in the world
