Answer:
The intense pressures in the deep ocean make it an extremely difficult environment to explore
Step-by-step explanation:
Most of the deep ocean is cold, usually lower than the temperature in your refrigerator. Deep-sea animals don't mind the cold at all, and many can only survive and grow in the cold. Food is scarce in much of the deep sea, in part because photosynthesis only takes place at the ocean's surface where there's sunlight.
