Oceans Review Part 1

Oceans Review Part 1

An ocean current is a mass of moving water in the ocean.

• Surface currents are driven by wind powered by energy from the sun.

• Deep Ocean Currents are driven by salinity, temperature and deep ocean features.

Multiple Choice

Oceans move energy in the form of_________?

• Salt

• Heat

• Water

• Oxygen

Multiple Choice

Regular movement of water deep below the ocean's surface are called__________?

• Shallow Currents

• Warm Currents

• Deep Ocean Currents

• Surface Currents

Upwelling is when near shore winds push the warmer water away and colder nutrient rich water is pulled up.

• Transports nutrients that supports plants growth.

Multiple Choice

What is upwelling?

• Cold water sinks and transports oxygen to the deep ocean.

• Near shore winds pushes warmer water away and pulls cold nutrient rich water to the surface.

• I don't remember can you please explain?

Ocean Zones

• Photic zone- Sunlight penetrates, and photosynthesis occurs.

• Aphotic Zone- Little to no sunlight penetrates these depths, cooler temperatures and increasing pressure.

• Abyssal Zone- No light exist, cold water temperatures and extreme pressure

Multiple Choice

Ocean zone where sunlight can penetrate and photosynthesis occurs.

• Abyssal Zone

• Aphotic Zone

• Photic Zone

• Open ocean

Multiple Choice

Why does the epipelagic zone support the most biodiversity in the ocean?

• Photosynthesis occurs here so there are phytoplankton and food to eat and oxygen is plentiful

• Because it has many different organisms that do not eat each other.

• Because the temperature he does not change very often which makes adapting easier.

• Because this zone is sooo dark that organisms can not see each other.

There is no meeting tomorrow, but you still have to take your quiz. I will post the quiz on Google Classroom. Study and complete your practice quiz.
