Sound travels a lot faster in water.
What is how does water effect sound?
100
If you are lighter than water then it will be easier to stay at the surface.
What is how does buoyancy affect both swimming and drifting marine organisms.
100
Kinetic energy in the random movement or vibration of individual atoms and molecules in a substance.
What is heat
100
kinetic energy in the random movement or vibration of individual atoms and molecules in a substance.
What is heat?
100
Heat capacity is how much energy it takes to raise 1 gram of a substance 1 celsius.
What is heat capacity?
200
Dolphins and whales use echolocation.
What is how marine mammals use sound in water to their advantage?
200
Fahrenheit and Celsius
What is the two common systems used to measure temp.
200
Thermocline is the transition between a colder, deeper, water layer and a warmer upper layer of water.
What is thermocline?
200
the transition between a colder, deeper water layer and a warmer upper layer of water.
What is thermocline?
200
A layer surface are make the cell more efficient. More cell membrane allows for more diffusion of fluids.
What is why a high surface to volume ratio important to cell function?
300
Heat capacity is how much energy it takes to raise 1 gram of a substance 1 degree celsius we measure it by (cal/g/ celsius)
What is how does water movement affect the distribution and survival of the marine life?
300
Celsius
What is the system used to measure temp. by most scientist?
300
A larger surface area makes the cell more efficient. More cell membrane allows for more diffusion of fluids.
Why is a high surface to volume ratio important to cell function?
300
The ocean forms layers. Dense water is heavy and sinks below less dense layers.
What is how the ocean is stratified by density?
300
the role of iron is that if there is a lack of it limits phytoplankton productivity in the ocean.
What are the roles of iron and other trace metals in marine organisms?
400
Heat capacity is how much energy it takes to raise 1 gram of substance 1 degree celsius.
What is heat capacity?
400
The measure of how fast molecules/atoms in a substance move.
What is temperature?
400
Water becomes less dense it freezes. Most substances become denser as they cool and less dense as they warm.
What is unique characteristics does water exhibit as it turns from vapor to liquid to ice?
400
The amount of acid in the water.
What is the factors that affect seawaters PH?
400
Diffusion and osmosis regulate the salt intake and excretion in all marine animals, birds, and reptiles.
What is how diffusion and osmosis affect marine organisms?
500
seawater does not fluctuate in temp. nearly as much as air does.
What is the advantage does ocean-based existence have over land-based existence with respect to temp.
500
They both have to do with movement. (that is not a difference)
What is how do heat and temperature differ?
500
the measure of how fast random movement or vibration of individual atoms and molecules in a substance.
What is temperature?
500
The deeper you go in the water the lower the PH
What is why PH changes with depth?
500
Sea salts come from rain, runoff, erosion and other natural forces.
What is where does sea salt come from?
