Science
The first step in scientific inquiry.
What is an observation/question?
This property of water is sometimes called surface tension.
What is cohesion?
Life zone beyond the furthest reaches of high tide.
What is the supratidal zone?
This term refers to a mixture of salt and freshwater.
What is brackish?
One of the sources of the ocean's salts.
What is river runoff, hydrothermal vents, volcanic activity
Variable not manipulated by the scientist.
What is the dependent variable?
The creation of a meniscus in a test tube is an example of this property of water.
What is adhesion?
Life zone beyond the reach of sunlight.
What is the aphotic zone?
This prevents the water around hydrothermal vents from boiling.
What is the pressure?
The pH of sea water.
What is 8.0?
Variable manipulated by the scientist.
What is the independent variable?
The polarity of water has led to this nickname.
What is the universal solvent?
The largest life zone in the ocean.
What is the pelagic zone?
This ecosystem is commonly used as a nursery by many species of fish.
What is an estuary?
Approximate depth in the water column where dissolved oxygen (DO) is at its minimum.
What is 1000m?
This branch of mathematics is used by scientists to analyze the data they collect.
What is statistics?
This is the pH of pure water.
What is 7.0?
The life zone that is most affected by the tides.
What is the intertidal zone?
This is the dominant species of grass in salt marsh communities.
What is cordgrass?
Point/line in the water column where salinity begins to dramatically increase.
What is the halocline?
This process ensures that scientists conduct their work proficiently and ethically.
What is peer review?
The unequal sharing of electrons creates this property of water.
What is polarity?
Name given to the part of the pelagic zone with depths of 200m or less.
What is the neritic zone?
The process used by extremophile bacteria living near hydrothermal vents to create sugars.
What is chemosynthesis?
This percentage of seawater is composed of water molecules.
What is 96.5%?
