|What is the percentage of nitrogen?
|What does water molecules look like?
|Oxygen at the top and hydrogen at the bottom two.
|What does cohesion mean?
|The attraction among molecules that are alike.
|What does adhesion mean?
|The attraction among molecules that are not alike.
|The density of ice is lower than the density of the same volume of liquid water.
|The density of freshwater is lowest at 4 degrees Celsius .
|The particles of liquid water are closer together than the particles of the same volume of frozen water.
|What is the five ways in witch water is a unique compound?
|Ice floats in water, some substances dissolve into water, water forms drops when it spills, water is naturally as a solid, liquid, gas, and last is that water has a high specific heat.
|What is the definition of sea water?

|What happens in the surface zone?
|This is where most fish hang out and even turtles.
|What happens in the middle zone?
|A lot of squids hang out around here.
|What happens in the deep zone?
|It is around 1000m where submarines go down.
|What are the five earths oceans?
|Pacific, Atlantic, Indian, Southern, and Artic.
|Are ocean currents worm or cold?
|Does lots of things depend on ocean currents?
|The heat from the sun condenses or evaporates the water in the ocean leaving only salt behind?
|Warm air holds less or more heat than warm water?
|Thermohaline currents are warm salty or cold fresh water ocean currents?
|The amount of salt in the ocean has or has not changed?
|Data marker buoys drift with ocean currents or ocean temperatures?
|What is the percentage of salt in the ocean?
