Which are the most abundant dissolved gases in ocean water?

• oxygen, nitrogen carbon dioxide

• nitrogen, argon sulfide

• oxygen, argon and methane

Which type of ocean water would contain more dissolved oxygen?

• cold ocean water in polar regions

• warm ocean water in tropical regions

• temperate ocean water in subtropical regions

How do oceanic upwellings promote the growth of microscopic phytoplankton?

• They bring warmer water to the surface of the ocean

• They bring dissolved nutrients to the surface of the ocean

• They decrease the levels of oxygen at the surface of the ocean

• They decrease the amount of nutrients at the surface of the ocean

How is the amount of oxygen in ocean water affected by temperature?

• The amount of oxygen in ocean water increases as temperature increases

• The amount of oxygen in ocean water increases as temperature decreases

• The amount of oxygen in ocean water decreases as temperature decreases

• The amount of oxygen in ocean water is kept constant as temperature decreases

Which best describes the relationship between salinity levels and the amount of dissolved gases in ocean waters.

• As salinity increases, the amount of dissolved gases increases

• As salinity increases, the amount of dissolved gases decreases

• As salinity decreases, the amount of dissolved gases decreases

What causes ocean currents in the Northern Hemisphere to curve to the right?

• Earth's orbit around the Sun
• Earth's spinning on its axis
• Earth's magnetic field
• Earth's force of gravity

Why are fishing boats found near ocean upwellings?

• There is less vegetation there

• The water is less turbulent there

• Many marine species gather there to eat the nutrients brought to the surface

• Upwellings are found in more shallow waters, so boats do not need deep anchorage
