Question

which of the following statements describes an abyssopelagic zone?
this zone measures 20,000 feet to 36,000 feet below the surface, and has a name that means \unseen.\
this zone measures from 600 to 3,000 feet below the surface, and is sometimes referred to as the \twilight zone\ because of the amount of ambient light available.
this ecosystem is in a transitional area that is influenced by the cycle between low and high tides.
at the depths of 13,000 to 20,000 feet, this zone resembles a bottomless pit of complete darkness.

in which area would the largest coral reefs flourish?
southern ocean
baltic sea
north sea
indian ocean

Explanation:

• For the first question:
• The abyssopelagic zone is at depths of 13,000 - 20,000 feet. It is a zone of complete darkness.
• The zone that is 20,000 - 36,000 feet is the hadal zone.
• The zone 600 - 3,000 feet is the mesopelagic (twilight) zone.
• The intertidal (littoral) zone is influenced by tides.
• For the second question:
• Coral reefs thrive in warm, clear, shallow waters.
• The Indian Ocean has large areas of warm, clear water suitable for coral reef growth.
• The Southern Ocean is cold. The Baltic Sea has low salinity and often cold temperatures. The North Sea has variable temperatures and is not as ideal as the Indian Ocean for large - scale coral reef flourishing.

Answer:

• First question: At the depths of 13,000 to 20,000 feet, this zone resembles a bottomless pit of complete darkness.
• Second question: Indian Ocean
