Motions of the Ocean
These are traveling disturbances seen on the surface of water usually caused by wind.
What is a wave?
The steep area between the continental shelf and the continental rise; covered with sand, mud, and rocks
What is the continental slope?
Producers must have this main, essential item in order to survive.
What is sunlight?
This much of the surface of the Earth is covered by oceans.
What is: more than 70%?
This cause for the high and low tides we see throughout the day.
What is the gravitational pull from the moon?
Some waves that are caused by underwater earthquakes or eruptions of underwater volcanoes are known as this.
What are: tsunamis.
These are organisms that cannot make their own food and must get their energy from plants or other animals.
What are consumers?
This varies in oceans due to rates of evaporation, the depth of water, the rate of melting icebergs, and the amount of runoff from nearby land.
What is salinity?
This is what happens to water pressure as you go deeper into the ocean.
What is: increases.
The name of the “animal-like” plankton found the oceans.
What is zooplankton?
This produces much of the Earth's oxygen and serves as the base of the ocean ecosystem.
What is algea?
The four main causes for ocean currents.
What are: wind, differences in temperature, differences in density, and differences in salinity.
Long string of mountain chains that run along the ocean floor; formed from volcanic activity
What are mid-oceanic ridges?
The name of the “plant-like” plankton found the oceans.
What is phytoplankon?
Because of this - waves are actually able to form new landforms or adapt already existing ones.
What is deposition?
These are repeated rising and falling of the level of the ocean throughout the day.
What are tides?
The continental rise connects and joins the continental slope to the bottom of the ocean floor and "rises" back up due to this.
What are decayed fish, animal waste, soils and rocks?
This basic motion of the ocean is known as
“rivers deep within our oceans -- causes
circular movements”
What are currents?
These are a more complex, interconnected network of multiple food chains that show the many different feeding relationships within an ecosystem.
What are food webs?
Which depth of water do you think there is: less pressure, more light, warmer water, more salinity, and more organisms?
What is shallow (less deep) water?
