An internal forcing mechanism is a factor in Earth's atmosphere or on Earth that affects the climate. An External Forcing mechanism is a factor that is present, past the atmosphere. (ie. Axis tilt, distance form the Sun, solar storms)

Yeah, that's off.

Not sure how to hide this but... 22.1 to 24.5 over a 41000 year cycle called obliquity and is a factor if the milankovitch cycles.

Correct, your turn.

What drives thermohaline circulation and how does the water return to the equator?

[SomeGuyOutThere]

Answer (Click to Show Hidden Text)

It's driven by differences in density due to different water temperatures and salinities in ocean water, forming a large global "conveyor belt." It goes to the equator because the density is higher at the poles and salinity is slightly lower at the equator than its surroundings.
