Water Section Flashcards
Why is water so special?
Water is a solvent that allows chemical reactions. Having such a good solvent as water is critical for the functions of life.
What are water properties?
Water is the universal solvent / high heat capacity / water is a liquid / surface tension / adhesion / hydrogen bonds / boiling and freezing point
Name marine ecosystems
Coral reef / estuary / open ocean / mangroves / deep sea / intertidal zone / kelp forest / salt marsh / polar ecosystem
Why is it important to have a backbone?
Because it provides structure and support.
What are invertebrates/chordates?

How is “Life” classified?

Domain, kingdom, phylum, class, order, family, genus, species
What factors contribute to an ecosystem?
Light, radiation, temperature, water, chemicals, gases, wind, soil
What technology is used to study the ocean?
ROVs, sonar radars, hydrophones, submersibles, Geographic Information System (GIS), buoy system
Average ocean salinity? (ppt, psu)
35ppt / 34.7 psu
