Bill Nye on Ocean Currents

Front

What causes ocean currents?

Back

Ocean currents are caused by wind and the amount of salt in the water.

Front

Has the amount of salt in the ocean changed?

Back

No, the amount of salt in the ocean has not changed.

Front

What data markers drift with ocean currents?

Back

Buoys drift with ocean currents.

Front

Why are rivers and lakes not salty?

Back

Rivers and lakes are not salty because the minerals in the water flow to the ocean.

Front

How do ocean currents flow in the northern and southern hemispheres?

Back

The flow of currents in the northern and southern hemispheres are different, not the same.

Front

What is the primary factor that influences ocean currents?

Back

Wind is the primary factor that influences ocean currents.

Front

What role does salinity play in ocean currents?

Back

Salinity affects the density of seawater, which influences the movement of ocean currents.

Front

What are the two main types of ocean currents?

Back

The two main types of ocean currents are surface currents and deep-water currents.

Front

How do surface currents differ from deep-water currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep-water currents are driven by differences in water density.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, like ocean currents, due to the rotation of the Earth.
