Biomass is the total mass of living organisms in a given area.

What do oceans keep as "fairly constant"?
The oceans keep the TEMPERATURE fairly constant.
100
What are the 2 types of vertical divisions?
Photic and Aphotic zones
100
What are the 3 horizontal divisions?
Intertidal, Neritic, Oceanic
100
how does high levels of evaporation in oceans kill some animals?
by having a high level of salinity and some animals are not salt tolerant
200
What is the name of the tiny ocean plants that create the base of a food web that supports all sorts of life form?
Phytoplankton
200
Temperature range is smaller in lands near the ocean or away from the ocean?
Near the ocean
200
What is "Photic"?
Top 200 meters of the ocean that are penetrable by sunlight.
200
What is the intertidal zone?
known as the foreshore and seashore and sometimes referred to as the littoral zone, is the area that is above water at low tide and under water at high tide (in other words, the area between tide marks).

How do oceans connect to the water cycle?
Oceans are an enourmous reservoir for water in the water cycle
300
What does evaporation have to do with the moderation of climate in the ocean?
The evaporation absorbs water, but leaves the salt, so it makes the water more salty
300
What is "Aphotic"?
the area where therer is not enough light for photosynthesis.
300
What is the Neritic Zone?
The neritic zone is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately 200m in depth.
300
Why does Summer temperatures are not as hot, and winter temperatures are not as cold?
because water takes a long time to heat up or cool down.
400
How much oxygen does the ocean produce?
the ocean gives us more than half of the oxygen we have
400
What does condensation have to do with moderation of climate in the ocean?
When rain falls it makes more water, and it breaks the salt making the water less salty
400
What are the major defining characteristics of the photic division?
Organisms that photosynthesize depend on sunlight for food. Most of marine life belongs to this area.
400
What is the oceanic zone?
The oceanic zone begins in the area off shore where the water measures 200 metres (656 feet) deep or deeper. It is the region of open sea beyond the edge of the continental shelf and includes 65% of the ocean's completely open water.
400
what is the essential role in water cycle?
Most evaporation comes from ocens and most precipitation falls on ocean
500
How much of Earth is covered by water?
72% of Earth is covered by water
500
how do the oceans, along with the atmosphere distribute heat around the planet?
The oceans absorb heat near the Equator and then move that solar energy to more polar regions.
500
What are some defining characteristics about the aphotic division?
The aphotic zone makes up the majority of the ocean, but
has a relatively small amount of its life, both in diversity of type and in numbers.
