How many main ocean zones are there based on distance from shore?
Two
Three
Four
Five
Which ocean zone is described as the area where the ocean meets the land between high and low tides?
Neritic zone
Oceanic zone
Intertidal zone
Pelagic zone
What influences how many nutrients are in the water near the shore?
The amount of sunlight
The temperature of the water
The distance from shore
The salinity of the water
Why does the water closer to shore tend to have more nutrients?
Because of the warmer temperatures
Due to upwelling which moves nutrients up from the bottom of the ocean
Because of the higher salinity levels
Due to the presence of more aquatic plants
What type of marine life is mentioned as foraging for food at high tide in the intertidal zone?
Dolphins and whales
Seals, sea lions, and fish
Sharks and rays
Coral and anemones
What is the neritic zone known for?
Being the deepest part of the ocean
Having the least amount of sea life
Being home to much of the sea life we picture when we think of the ocean
Being devoid of nutrients
What does the neritic zone extend from and to?
From the surface of the water to about 100 feet below
From the surface of the water to about 200 feet below
From the shoreline to the end of the continental shelf
From the shoreline to the open ocean
What is the open ocean primarily composed of?
Coastal waters
The neritic zone
The benthic zone
The oceanic zone
What organisms primarily live in the benthic zone?
Plankton
Benthos
Zooplankton
Phytoplankton
What is a characteristic feature of the benthic zone?
It is where you find coral reefs
It is where you find black smokers and cold seeps
It is the warmest part of the ocean
It is the most biologically diverse part of the ocean
What defines the photic zone?
It is the zone where sunlight cannot penetrate at all
It is the zone where there is enough sunlight for photosynthesis
It is the zone below 200 meters depth
It is the zone where the water is the coldest
What happens to the water temperature and pressure as you go deeper in the ocean?
The temperature increases and the pressure decreases
The temperature and pressure both decrease
The temperature decreases and the pressure increases
The temperature and pressure both increase
What is chemosynthesis?
The process by which organisms use light energy to produce their food.
The process by which organisms use chemical energy instead of light energy to produce their food.
The process by which bacteria in the ocean clean hydrothermal vents.
The adaptation of organisms to high levels of pressure in the ocean depths.
Where would you find bacteria that use chemosynthesis?
In the shallow waters of the ocean where sunlight is abundant.
In freshwater rivers and lakes.
Around hydrothermal vents in the depths of the ocean.
On the surface of terrestrial plants.
