Ocean Properties
What percentage of salt is the ocean?
3.5%
The deepest point in the ocean (that we know of)
Challenger Deep
The deepest zone of the ocean. Few have explored this zone.
Hadal Zone
Two things that can affect the tides
The moon or the sun
Name at least one of the two parts of the ocean floor that start to angle downwards into the deeper sections.
Slope or Rise
What are the two main elements that make up the salt in the ocean?
Sodium Chloride
The submerged edges of the continental plates; the shallowest parts of the ocean
Continental shelf
This is the zone with little, to no light. Creatures here have to adapt to crushing pressure
Abyssal Zone
A pro and a con for using tidal energy generators
Example pro: doesn't pollute
Example con: can harm ocean life/doesn't provide enough energy
Water that is a mixture of freshwater and saltwater
Brackish
What are the three main elements that are NOT salt, that are in the ocean water?

An underwater canyon
Submarine canyon
The zone that experiences changing tides
Intertidal Zone
A tide that happens when the earth, sun, and moon form a right angle

Brine
What are the main ways in which salt and minerals can be deposited into the ocean
The five main basins of the ocean
Arctic, Indian, Pacific, Atlantic, and Southern
An zone of plentiful light in the open ocean

A tide that happens when the earth, sun, and moon form a straight line
Spring Tide

A sea is mostly surrounded by land on all sides, instead of being open like the ocean
What is the term for the amount of salt dissolved in water?
Salinity
The indistinct zone extending from the shore as far inland as we can recognize land features
The zone between the low-tide mark and the edge of the continental shelf
Littoral Zone
Name at least two types of winds
Trade winds, Prevailing winds, gyres
The place where a river meets the ocean
Estuary
