• The difference between high and low tides is greatest during a new or full moon.

All of the following can generate currents within Earth's oceans except–

Salinity and temperature both have an influence on ocean currents because both the temperature of water and the amount of dissolved salt in it affect–

• how quickly it evaporates.

• its ability to conduct electricity

• the latitude where it is found.

• the density of the water.
