Lesson 1
The Earth's oceans make up this percent of the surface.
What is "About 70%" ?
The top part of a wave, the bottom part of a wave.
What are "Crest, and trough."?
This causes surface currents.
What is "wind" ?
This is what PPT stands for, and ocean water typically has a ________ ppt for salinity.
parts per thousand. ~35 ppt.
The green water sunk to the bottom because it was the most _________ ?
What is dense?
These three elements make up the majority of the salt found in the oceans.
What are sodium, chloride, and sulfate.
High tides are _________ and low tides are _______ during a Spring Tide.
What is "very high" and "very low" ?
This is a type of surface currents which are looped / circular systems.
What are "gyres" ?
This is the measurement from one trough to the next trough.
What is the "wavelength" ?
The egg floated as we added more and more salt to the solution because __________.
What is "because the water became more dense than the Egg" ?
These 2 ways contributed to the development of Earth's oceans.
What are condensation from volcanic eruption and water from asteroids/comets?
The Earth, Moon, and Sun are in this type of position during Spring Tides. It occurs during these 2 moon phases.
What is "Directly in a line. Full and New Moon." ?
This is the direction that gyres move in the northern hemisphere.
What is "clockwise"?
The gulf stream is a system of warm, moist weather that moves up this coast.
What is the Eastern coast of the United States?
Blue tap water _______ when you added it to the clear salty water.
What is "floated" ?
These are the 3 different Ocean Zones and how temperature, salinity and density change at each zone in tropical regions.
Surface - warmest, least salty, least dense
Middle - less warm, most salty, denser
Deep - coldest, more salty than middle, most dense
This describes how particles in a wave move.
This type of current is a vertical current that is caused by warm water being blown away from the surface and replaced by colder, denser water from below.
What is "upwelling" ?
This is why the oceans are salty.
Ancient erosion over rocks and minerals.
A transverse way is a wave in which the particles and the wave move like this in relation to each other.
What is "at right angles" ?
This is why the salinity at the surface in polar regions is lower than in tropical/temperate regions.
What are "Polar regions have a lower salt content at the surface because freshwater melts at the surface."
This is how breakers form.
What is "when the wave height can no longer support the crest" ?
This is cycle takes thousands of year to complete and brings ocean water all around the globe.
What is "the global ocean conveyor belt" ?
These are some of the deepest parts of the Earth.
What are ocean trenches?
In the slinky lab, the faster you shook the slinky the __________ the wavelengths were while the frequency __________.
What is "smaller" and "increased" ?
