Significant Properties Of Ocean Water Flashcards
What is the significance of the oceans ability to absorb solar radiation and retain tropical heat?
It retains heat long enough to transfer it to polar regions
T/F Oceans absorb and release large amounts of heat?
True
What is a significant factor in stabilizing global climates and a major influence on hurricane activity?
Large bodies of water change temperature very slowly
How much does water pressure increase as you go down into ocean?
Increases 1 atmosphere per 10 meters
What is the average shelf water pressure?
13 atmospheres
What is the average Abyssal plain water pressure?
500 atmospheres
What is the average water pressure of the deepest ocean trench?
1100 atmospheres
T/F sunlight is absorbed quickly, even in extremely clear water
True
How much light is absorbed at 1 meter into ocean? At 10 meters? At 100 meters? At 1 kilometer?
1 meter-60% of light absorbed
10 meters- 80% of light absorbed
100 meters- 93%
1 kilometer- 100%
What are the first three types of light that are absorbed first? (In order)
- Infrared light (heat)
- Red light
- Ultraviolet lights
In order which colors are absorbed first in ocean depths?
Red, orange, purple, yellow, green, dark purple, the finally blue
Which frequency is absorbed faster, high or low?
High frequency sound is absorbed faster
Which frequency travels farther, high or low?
Low frequency travels farther under water than high frequency
How much faster does sound travel under water than through the air?
Sounds travels 5 times faster through water than through the air
What is the SOFAR later?
The zone minimum sound velocity, but greatest efficiency. Slower but better
