What I have learned...

1. Ocean currents can be affected the rise and fall of tides called tidal currents

2. Wind near the ocean surface can also drive the currents

3. Thermohaline circulation moves way slower than tidal or surface currents

I wonder...

1. Why would the salinity of an ocean affect the movement of the ocean?

2. Are there any currents that occur at the sea floor?

So this matters because...

1. You could get hurt by an ocean current if you don't know how strong it's or how it's being caused.
