What are the names of the ocean basins?
Pacific, Atlantic, Arctic, and Indian.
-
What is the largest ocean?
The Pacific.
-
Does sea level constantly change?
Yes, it changes all the time forcing oceanographers to use a averaging system that allows them to measure the sea level even though it changes all the time.
-
What is the local sea level?
It is the sea level that is more local to an ocean basin such as the Atlantic or the Pacific.
-
What is a shore?
It is an area where the ocean and land or lands or island or islands meat up.
-
What is the continental shelf?
It is the drop off point of where the rise falls.
-
What is an abyssal plain?

-
What is a continental slope?
It is the area in which the shore slopes down to the continental shelf.
-
What is the oceans salinity?
It is how much salt is in the sea.
-
Is it possible that the ocean was salty before the flood?
Yes, it is very likely that the ocean was salty before the flood.
-
What is brackish water?
It is water that is less salty but is in the early stages of becoming salt water.
-
What is with temperature rising and falling in the ocean?
Hot water is at the top, while cold water is at the bottom.
-
What is density?
It determine whether an object will sink or float.
-
What is the speed of sound?
It is an object or thing that is going faster than the travel of sound.
-
What is echolocation?
It is how animals that cannot see, use to swim and hunt.
-
What are the different environments of the ocean called?
Photic Zone, Aphotic Zone, and Abyssal Plane
-
What are the light conditions in the Aphotic Zone?
It is completely black due to the lack of sun light bleeding through the ocean.
-
What is the significance of the carbon cycle?
It keeps us alive and recycles all the different types of carbon, just like the other cycles do.
-
What is the Photic Zone?
Its just like the Littoral Zone, except the salinity and clarity levels are completely different.
-
What is the Littoral Zone?
It is an area where the waves crash and everything gets washed up on the sea.
-
What dot he marine organisms that live in the littoral zone require of?
A strong body, because they need to be able to survive the violent crashing waves.
-
What is the Hadal Zone?
It is like the Abyssal Zone, accept it has a little more light than the Abyssal Zone, it also has more planes.
-
What is the marine nitrogen cycle?
It is a cycle in which all marine organisms after they die the nitrogen inside them is recycled.
-
What would happen if the nitrogen inside marine organisms did not exist?
Life on earth would soon perish due to nitrogen poisoning.
-
How do the animals in the Abyssal plane eat?
They eat the living organic matter that has been falling to the ocean floor from the very top.
-
How far down is the Abyssal Planes?
About 20,000 feet.
-
Why can phytoplankton not survive in the deep ocean areas?
Because they use the sunlight for their food.
-
Where is the Photic Zone located?
Near the surface, about 100-200 m
-
Where is the Aphotic Zone located?
About 3,000 4,000 m, or 13,000 ft.
