Question 11 of 15 currents are caused by temperature and density differences.
A. Surface
B. Longshore
C. Deep
D. Tsunami

The current answer is - Deep.

Explanation:

If the water becomes denser, movement of water below the surface, and surface water is cool then Deepwater currents are formed. These currents are formed mainly due to differences in density, temperature and salinity.

These currents move towards the equator from the poles that carry cold water slowly than the surface water currents. It is due to density difference and temperature difference in the water.

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.
