Oceans 1
What is the process that brings cold nutrient rich water to the surface of the ocean?
What is upwelling?
What causes tides?
The pull of the Moon, ocean currents, wind
What causes waves?
What is wind?
What are currents?
What is when a body of water moves around the globe due to temperature and density differences?
Where is the location of the Midnight Zone?
What is below the ocean's surface where there is no sunlight. Pressure increases and temperature decreases?
Why are estuaries known to have brackish water?
a mixture of fresh water draining from the land and salty seawater.
What can cause salinity of the ocean to increase?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean.
What are threats to estuaries?
What is human activity, pollution, boats, and overfishing?
What are the ocean zones?
What are the sunlight, twilight, midnight, abyss, and hadal OR epilagic, mesopalagic, abyssopelagic and benthic zones?
What are corals reefs?
Coral reefs are large underwater structures composed of the skeletons of coral, which are marine invertebrate animals.
How do estuaries act as a nursery?
Nurseries of the sea because so many species reproduce and the offspring start out there
Why do most organisms live in the sunlight zone?
there's a lot of sunlight in the neritic zone, green plants grow there, providing a high oxygen and food
Which zone is the biggest?
sunlit zone
Give examples of organisms that live in the photic zone.
What are Fish, Turtles , Seeweed?
What is the reationship between corals and their Zooxanthellae?
What is mutualism?
What types of animals live in the intertidal zones?
Sea stars, Green algae, urchins, or ones that can withstand dry and wet environments.
Why is the sunlight zone important?
Photosynthesis must take place by the ocean's producers to start food webs and make 90% of the world's oxygen.
How is upwelling important for humans and marine life?
The deeper water that rises to the surface during upwelling is rich in nutrients causing fish to reproduce
What is one of the major problems facing our oceans?
Contamination, Pollution
What causes upwellings in oceans?
Upwelling often happens where wind blows along a coastline moving warm water away from the coast allowing for cold nutrient rich water to move upwards.
Which zones of the ocean does photosynthesis occur?
Sunlight Zone
In which ocean zone will you find the following: Highest pressure?
What is the deepest part/abyss/hadal zones?
What two factors can cause the salinity of the ocean to increase?
What are evaporation and freezing?
How does salinity affect the type of organisms that live there?
Many marine organisms are highly affected by changes in salinity. This is because of a process called osmosis
What two things do upwellings bring to the surface of the ocean?
cold water, Fish, nutrients.
