A (How is density related to deep ocean currents?)

Density is what separates the layers of water and when a mass of water gets denser, it forms deep ocean currents

B (How does salt concentration change the density of ocean water?)

Increasing salinity also increases the density of seawater, the less salt, the less dense

C (How does temperature change the density of ocean water?)

As the temperature goes down, the density increases, as the temperature goes higher, the density decreases

A (What causes surface currents?) - the coriolis effect causes winds and currents to form circular patterns

B (What is a gyre?) - a spiral or a vortex in water

C (Explain the coriolis effect) - a mass moving in a rotating system, and deflects moving objects

A (What causes waves on the surface of oceans?)- wind transferring its energy to water

Can travel long distances

B (Describe the parts of a wave: crest, trough, wavelength, wave height)

Crest- highest point that the wave rises to

Trough- the lowest point the wave sinks to

Wavelength- the distance between the crests on two waves

Wave Height- distance between crest and trough
