Ocean test honors 2025

Microscopic, free-floating, autotrophic organisms that function as producers in aquatic ecosystems

• Phytoplankton

• Zooplankton

• Nekton

• Benthos

Causes Coriolis effect:

• Wind

• Salinity

• The Rotation of Earth

• Deep currents

The concentration of dissolved salts in water.

• Salinity

• Halocline

• Thermocline

• 50%

Animal-like drifting one-celled and small multicellular organisms. Consumers- will eat each other or the phytoplankton.

• Phytoplankton

• Zooplankton

• Nekton

• Benthos

When the tidal range is greatest. (Sun and moon are pulling in a line- full moon and new moon).

• Spring tide.

• Neap tide.

• High tide.

• Low tide.

The Pelagic (water) environment that is beyond the continents' edges. Divided into many zones, from Photic to Abyssal and Hadal.

• Neritic zone.

• Open ocean.

• Bathyal zone.

• Intertidal Zone

Top 200 m of ocean; sunlight can penetrate; plankton feeds a food chain.

• Neritic Zone.

• Photic Zone.

• Bathyal zone.

• Aphotic zone.

The zone located above continental shelves. This is the zone where life is most abundant. Why?

• Photic zone is here, but not in the open ocean.

• Nutrients from the continent wash into the ocean.

• Salinity is low here.

• The Neritic Zone is warmer.

The most abundant salt in sea water:

• Potassium permanganate.

• Sodium Chloride.

• Potassium dichromate.

• Copper Sulfate.

We experience 2 high tides and 2 low tides every

• Day
