Salt Water Review

As a submarine rises from the ocean floor to the surface...

• pressure will be the only change

• density will increase and temperature will decrease

• salinity will decrease because of sea creatures

• temperature will get warmer and salinity and density will decrease

Even though rivers empty freshwater into oceans, the salinity stays balanced because

• Sea creatures eat the salt

• Fresh water constantly evaporates

• Sea creatures drink the fresh water

• The salt water freezes in glaciers

No matter the location, the same salts are always in the ocean proportional to the water

• true

• false

Salt in the ocean comes from

• rocks

• underwater volcanoes

• hydrothermal vents

• all of the above

This guides deep ocean currents

• wind

• Coriolis Effect

• density differences

• water pressure

Ocean water is the most dense when

• it has a high salinity and is cold

• it has a low salinity and is warm

• it has a high salinity and is warm

• it has a low salinity and is cold

This is what causes the Coriolis Effect

• gravity

• Earth's revolution around the sun

• The Moon revolving around the Earth

• Earth rotating on its axis

Salinity is

• the type of salt in ocean water

• evaporated salts from oceans

• the type of sodium in water

• the amount of dissolved salt in water

If you build a sandcastle at the beach, it will eventually be washed away because of

• the low tide

• erosion

• the high tide

• weathering

This type of salt makes up most of the ocean's salt

• basalt

• sulfur

• sodium chloride

• hydrogen peroxide
