Question
Read the log book Water Masses to learn how temperature and salinity affect parcels of water. If you need more assista make a note where you got your information. Answer the questions and complete the following tasks using the log book, Objective Acquire and analyze data necessary to assess surface and deep ocean current activity and water masses. Questions 1. Thermohaline currents are caused by (select all that apply): wind coriolis effect - gravity . density 2. What happens to density values as you descend to the bottom of the ocean? - increases . decreases " no change 3. What happens to the salinity as you descend to the bottom of the ocean? . increases * decreases " no change 4. What happens to the temperature as you descend to the bottom of the ocean? increases * decreases " no change 5. Where does all deep water in the world's oceans originate? " poles " mid latitudes " equator depend:s 6. Use the following thermohaline currents to answer questions 7, 8, 9, and 10:Explanation / Answer
1. density option is correct
Thermohaline currents (vertical) caused by sinking of high density waters & rising of low density waters.
2. increases option is correct
The temperature of the ocean decreases and decreases as you go to the bottom of the ocean. So, the density of ocean water increases and increases as you go to the bottom of the ocean.
3. no change option is correct
After you pass the surface zone, salinity is constant and remains the same. There is no evaporation and no addition of freshwater as you descend through the water column, so the salinity doesn't change.
4. decrease option is correct
The temperature of the ocean decreases and decreases as you go to the bottom of the ocean. So, the density of ocean water increases and increases as you go to the bottom of the ocean.
5. poles option is correct
The two main sources of deep water are at the poles, where the cold temperatures.
