The basis of the ocean food chain are these tiny plant like organisms.
What is phytoplankton.
100
The shallowest zone of the ocean ranging from the surface to about 600 feet down is this one.
What is the Neritic Zone
100
The long sloping incline from the end of the continental shelf to the abyssal plane on the bottom of the ocean is this feature.
What is the continental slope.
100
Water in the polar regions freezes into ice and leaves behind cold, salty, dense water that sinks rapidly creating a current.
What is a density current
200
Which ocean is the warmest?
What is the Indian Ocean
200
Among the plankton the ones that are animal-like are known this.
What is zooplankton.
200
Animals and plants that live along the bottom of the ocean are known by this term that describes the zone they live in.
What is benthic
200
The long line of seamounts, or undersea volcanic mountains that run through the Atlantic Ocean are known as this land form.
What is the Mid-Atlantic Ridge.

What is a current
300
Which ocean is the coldest ocean?
What is the Southern Ocean
300
Any organism larger than plankton that swim on their own are called this.
What is nektons
300
The name if the zone the describes how deeply light can penetrate into the ocean.
What is the photic zone
300
Trenches under the ocean mark deep points where two continental plates meet. At these points a heavy tectonic plate forced a lighter one below it back into the mantle. That is an example of this sort of zone.
What is subduction zone
300
When winds blow warm water away from the shore allowing deep, cold currents to bring nutrients to the surface where plankton can get at them.
What is an upwelling.
400
In this ocean new seafloor is made along volcanic mid ocean ridges.
What is the Atlantic Ocean.
400
Any organism that can make its own food, usually green plants, are known by this term.
What is producer.
400
The zone that lies between the low tide mark on a beach and the high tide mark on a beach is known as this zone.
What is intertidal zone.
400
An area where the ocean mixes with fresh water from a stream or river, creating a unique ecosystem, is known by this term.
What is an estuary
400
A wave a meter or more high, sometimes thousands of miles long, caused by the rotation of the Earth and the interaction of the gravity of the Earth, Moon, and Sun.
What is a tide.
500
Which is the smallest of the world's oceans?
What is the Arctic Ocean
500
An organism that cannot make its own food, and must consume others is known by this term.
What is a consumer.
500
The ocean zone that reaches from 600 feet down to the bottom of the ocean is known by this term.
What is oceanic zone.
500
A large body of water, usually part of an ocean, and usually defined by its border with a land mass.
What is a sea.
500
A warm surface current that sometimes appears in winter. It runs from Australia towards North America and can badly affect both fishing, and weather in North and South America.
