71% and 97%
________ are caused by the __________ attraction between the ______ and the oceans.
Tides, gravitational, moon
Ocean depth divided into 5 zones based on the amount of _________ penetrates the water.
Sunlight
Developed in the 1960s, this vehicle can carry one or more people. Its development allowed for deeper exploration of the sea.
Submersible
5 parts of the water cycle
Evaporation, transpiration, condensation, precipitation, accumulation/runoff
This part of the water cycle transports salt and other minerals to the ocean.
Runoff
4 types of tides
High, low, neap, spring
Name my 5 zones in order from closest to the surface to deepest.
Sunlit, twilight, midnight, abyss, trenches
Type of submersible that cannot carry people and can explore the deepest parts of the ocean. They are controlled by the mother ship or by a submersible.
Remotely operated vehicle (ROV)
The deepest trench in the Pacific Ocean
Mariana Trench
Why is there more oxygen near the surface of the ocean than in the deeper parts?
Oxygen is produced by tiny plants called phytoplankton that grow near the surface of the water.
A _____ is generated from friction of the _____ with water molecules. The tallest point is called the _____. The lowest point is called ______. Two measurements we use to describe them are ______ _______ and ______________.
Wave, wind, crest, trough, wave height, and wavelength
_________ ______ stretches out from most of the continents and then drops sharply at the _________ _______. The relatively flat area past this slope is called the _______ ______. In this plain, underwater mountains called ___________ are found.
Continental shelf, continental slope, abyssal plain, seamounts.
Underwater laboratory that can operate up to 120 feet below the surface of the water.
Aquarius
Magnesium, bromide, and salt
Oceans affect the weathers in these 3 ways.
Provide moisture for storms that develop over oceans and move toward land.
Water changes temperature more slowly than land, so the sun heating the ocean causes much of the wind around the world.
Coastal areas have mild winters and cooler summer because of heat stored in oceans.
Moving water keeps the ocean clean by.....
Circulating oxygen and moving debris out to sea to be eaten or decomposed by sea creatures.
_________ are deep valleys in the ocean floor. ________ are long mountain chains on the ocean floor. Both are believed to be the result of plate tectonics.
Trenches and ridges
Why does an ROV need headlights?
To see what they are exploring since there is no sunlight in the deepest parts of the ocean.
Coral reef
