Why don't aquariums display fish and creatures that live deep in the ocean?

• They swim too quickly.

• Aquariums don't think people are interested in them.

• They are adapted to intense pressure and will not respond well to living in an aquarium.

• Aquariums can't provide the best food for these creatures.

An oceanographer collected data on the physical properties of the sea in several locations. Use the data below to answer the question. What is the relationship between temperature and depth in the ocean?

Location Temperature Salinity Depth No. of Snails

site 1--------- 15 C------------ 31 ------22----------56

site 2--------- 22 C------------ 31------ 7----------- 31

site 3--------- 16 C------------ 30------17---------- 49

• deeper water is also cooler water

• deeper water is also warmer water

• deeper water is saltier

• no relationship exists

A young scientist places a drop of freshwater and a drop os seawater on glass slides. The slides are heated slowly so that the water evaporates. How will the slides look?

• They will both look the same.

• The seawater will leave a salty deposit, but the freshwater will leave no trace.

• The freshwater slide will have a white ring, but the seawater will leave no trace.
