which is correct about warm currents?
a. They are surface currents.
b. They make landmasses warmer.
c. They moved from the poles to the equator.
d. They are denser than cold currents.
b. They make landmasses warmer.
All of the options are partially correct.
a. Warm currents can indeed be surface currents, but they can also occur at various depths within the ocean.
b. Warm currents can warm the landmasses they come in contact with, but this is not always the case.
c. Warm currents can flow from the poles towards the equator, but there are also warm currents that move in other directions.
d. Warm currents are generally less dense than cold currents, as warm water is less dense than cold water. However, there can be exceptions depending on specific conditions.
