Properties of Water
This property allows water molecules to stick to itself
What is cohesion?
This sandy part of the ocean covers from high tide to low tide. It has a variety of plant and animal life.
What is the intertidal zone?
This scale goes from 0 to 14 and healthy water for marine ecosystems is around 7 to 8.5 on the scale.
What is the pH scale?
This makes up 97% of the world's water supply. And is where most evaporation and precipitation occurred.
What is the ocean?
All food chains must start with this:
Plants
This property allows water molecules to adhere to other things
What is adhesion?
This part of the ocean is pitch black. No photosynthesis occurs here.
What is the midnight or abyssal zone?
This indicator of water quality uses signs of life and the variety of it to determine healthy or unhealthy water.
What are bio-indicators?
This underground supply of water is a storage place for potable freshwater. It can be pumped using a well.
What is an aquifer?
This word means the amount of salt in a body of water
What is salinity?
This allows very light items and organisms to walk on water.
What is high surface tension?
This part of the ocean gets its name from getting the most sun. It is the only zone to get enough sunlight for photosynthesis to happen.
What is the sunlight or photic zone?
Warmer water holds less of this molecule, that is necessary for animal life in the water.
What is dissolved oxygen or o2 ?
The land that is drained by a river and its tributaries. It drains into an estuary or ocean.
What is a river basin?
This process is when plants let water evaporate off of their leaves
What is transpiration?
This property allows the ocean to absorb the suns warmth without raising temperature.
What is high specific heat?
This zone sits atop the continental shelf and is home to abundant marine ecosystems. This area provides lots of protection from predators.
What is the neritic zone?
This indicator of water quality, when it is high causes temperature to go up, and oxygen to go down.
What is turbidity?
This mix of salty and freshwater is a home and safe breeding space for many animals. It helps to control erosion and flooding and is full of rich nutrients from the rivers that feed into them.
What is an estuary?
This type of pollution comes from a single source like source like a factory or company dumping into a body of water. It is regulated by the Environmental Protection Agency. (EPA)
What is point-source pollution?
In water the density of a solid is less than that of a liquid. It causes this to happen.
What is ice floats on water?
These outpourings of water come from the seafloor and are either extremely hot or cold. They help life survive on the ocean floor.
What are hydrothermal vents and cold seeps?
These chemicals cause eutrophication in the water leading to high turbidity and decay in the water.
What are nitrates and phosphates?
The majority of the freshwater on the earth (3%) is locked up in these:
What are glaciers?
The arrows in a food chain show these two things?
What is who eats who and the flow of energy?
