Water Quality
Organisms that help signify the health of an ecosystem or environment.
What are bioindicators
Where can you find fresh/clean water?
(Give 3+ answers!)
Rivers, lakes, groundwater, glaciers
Give three stages of the water cycle
(i.e., evaporation)
Condensation, transpiration, precipitation, percolation+
Agricultural runoff with pesticides, herbicides, and fertilizers contaminates water sources.
What is pollution?
Light that is produced by marine animals.
What is bioluminescence?
The word that describes water when it is cloudy or hazy.
(HINT: It has to do with algae and sediment!)
What is Turbitidy
Using sonar and satellite imagery.
Water soaks into the ground, replenishing underground water sources like aquifers.
How does infiltration work?
When people throw trash like plastic bottles and bags into the ocean.
What is marine litter?
(You still get points if you just said litter)
The colorful underwater ecosystem, home to thousands of marine species
The measure of acidity or alkalinity in a water source.
(HINT: 7+)
Openings on the floor where hot, mineral-rich water erupts.
What are Hydrothermal Vents?
The process where water flows across the Earth's surface and is collected in rivers, lakes, and oceans, or it seeps into the ground
What is runoff?
Dramatically depleting fish populations, disrupting food chains, and potentially leading to species extinction.
The effects of overfishing
The ocean zone where sunlight CAN reach and is home to most marine life.
The amount of gas (that aquatic life needs to breathe) that is present in a body of water.
What is dissolved oxygen?
What is the percentage of water that covers Earth's surface?
71% of Earth's surface is covered in water
97% Saltwater - Freshwater 3% - Frozen 2%
When water vapor cools and changes back into liquid droplets.
(It forms clouds in the atmosphere)
Fishing practices that unintentionally catch and kill non-target species.
What is bycatch?
Organisms that produce energy with sunlight through photosynthesis.
What are producers?
This is the process where scientists collect water samples from lakes, rivers, or oceans to check for things like pollution or harmful bacteria.
What is water testing?
The deep-sea zone where no sunlight reaches. Many creatures produce bioluminescence since it is so dark.
What is the midnight zone?
The process involves water vapor moving directly from ice or snow into the atmosphere without first becoming liquid.
What is sublimation?
Tiny plastic particles that are found around the ocean and are eaten by marine life.
What are microplastics?
The 3 types of marine life that are either able to swim against a current or drift along with it.
Plankton, Nekton, and Benthos
