Which contributes most in supporting life on the deep ocean floor?

• lack of predators

• extreme water pressure

• cold water temperatures

• hydrothermal vents

NGSS.MS-LS2-3

Deep ocean technology has discovered organisms in hydrothermal vents that do not rely on sunlight to survive. What do these organisms use as their energy source?

• chemosynthesis

• electrical charge

• hydropower

• thermal heat

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

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

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

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

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

Which statement about oceans is true?

• Pressure is lower on the ocean floor.

• Water temperature increases with depth.

• More photosynthesis occurs in the warmer surface waters.

• The colder, deeper waters are less dense than the surface waters.

What environmental factors have the greatest influence on determining the life forms that

are found in the three different ocean zones?

• pressure, sunlight, and temperature

• oxygen, nitrates, and sunlight

• pH, temperature, and turbidity

• currents, pressure, and salinity

Oceanographers noticed the absence of aquatic plants in the deep ocean. What factor mainly prevent the growth of plants in the deep ocean?

• high pressure

• absence of sunlight

• high salinity of water

• low water temperature

Tags

NGSS.MS-LS2-1

Why is productivity greatest near the ocean’s surface?

• salinity of water

• photosynthesis occurs there

• it is bigger

• more predators live there
