Ocean Zones
An area where salt and fresh water meet.
What is an estuary?
This type of ocean technology wasn't mentioned in the notes, but it allows for many things to be transported across bodies of water.
What is a boat?
An area where fresh water from rivers meets salt water in oceans.
What is an estuary?
Cleaning water so that it may be used again or released to the environment.
What is water treatment?
The majority of the water cycle takes place over this type of water.
What is salt water?
Organisms in this zone must adapt to being underwater and above water for multiple hours per day.
What is the intertidal zone?
This type of technology uses pulses of sound to measure the distance away something is.
What is sonar?
Since estuaries filter out sediments and pollutants from rivers before they flow out into the ocean, clean water in estuaries provides this kind of habitat for organisms.
What is a safe habitat?
Living organisms who can show scientists the health of the water system due to their presence and population number.
What are bioindicators?
Only this percentage of water on Earth is freshwater.
What is 3%?
This ocean zone is dark and cold. Light won't make its way down here.
What is the deep ocean?
These large structures float in the ocean to signal ships and collect data from the ocean.
What is a buoy?
Estuaries can act as a buffer zone and absorb water from floods, storm surges, and tides. This does what for humans?
What is protects humans?
Nitrates and phosphates are a major cause of this process which can be deadly to the organisms living in ponds or lakes where it occurs.
What is eutrophication or algae blooms?
Water that is suitable for drinking is called this.
What is potable?
This ocean zone is where most oxygen on Earth is produced. It is also the zone that receives the most sunlight, heat, and energy.
What is the open ocean?
We are able to see the bottom of the ocean and collect samples from it because of this ocean technology.
What are ROVs?
Since estuaries are the source of a lot of our fish and provide protection to our shores it is important to do this...
What is protect and conserve estuaries?
This type of chemical compound enters water systems from fertilizer, sewage, manure runoff, and septic tank leakage.
What are nitrates?
Most of the freshwater on Earth is found as this state of matter.
What is solid ice?
Since organisms in the deep ocean cannot rely on photosynthesis to produce energy in their ecosystem they use chemicals to make energy through this process instead.
What is chemosynthesis?
Humans have had issues exploring the depths of the ocean because of this.
What is increasing pressure?
Water in estuaries is a mix of fresh and salt water, often called this.
What is brackish?
These compounds enter water systems from laundry, cleaning, and industry discharge.
What are phosphates?
Humans drill into these underground rock layers to use them as a source of potable water.
What are aquifers?
