Earth's Ocean
Name a way that the ocean floor can be studied
What are sonar, satellites, underwater vessels, and deep-sea drilling?
The flat part of the ocean floor
A disturbance that transfers energy through ocean water
What is a ocean wave?
The cause of deep ocean currents
What is the result of differences in density?
The zone where water temperature drops with increased depth faster than it does in other layers
What is the thermocline?
The result of diverging plates
What is a mid-ocean range?
four natural events that can cause natural disaster and also large waves
What are earthquakes, volcanoes, landslides, and meteorites and asteroids?
These affect surface currents.
What are continental deflections, the Coriolis effect, and global wings?
Chemical and physical characteristics of ocean water
What are chemical characteristics which include salinity and the amount and type of gasses in the water.....and
Physical characteristics which include temperature and density?
The three parts of the continental margin
What is the continental shelf, continental slope, and continental rise?
how to calculate wave speed
What is the multiplication of wavelength and frequency?
how surface currents are powered
What is the sun heating the surface, heat rising, causing low pressure in the atmosphere, and causing wind to form?
The 5 main oceans
What are the Pacific ocean, Atlantic ocean, Southern ocean, Indian ocean, and the Arctic ocean?
the result of subducting plates
What is an ocean trench?
What is a series of waves that form when a large volume of ocean water is suddenly moved up or down?
Describe the transfer of energy in a convection current
What is energy being lost to the surroundings as it cools and then the cool water absorbs the energy and replaces the water that is leaving the surface currents?
The overall salinity of seawater
What is 3.5%
Submerged volcanic mountains...and what they are called above sea level
What are seamounts?....What are volcanic islands?
This happens when a wave reaches the shore
when the waves reach water shallower than one-half their wavelength, they begin to interact with the ocean floor. As waves touch the ocean floor, they transfer the energy to the ocean floor. As a result the water at the bottom of the wave slows down, wave height increases, and the waves form closer together. The top of the wave travels faster than the bottom, gravity putts the crest down (breaking) and the wave transfers the energy to the shore
The two things ocean currents transport. name examples of each.
What is energy and matter?
