Why do oxygen concentrations decrease with depth in sediments?

Why might a location in an ocean have low levels of primary productivity? Choose all that apply.

Oil can be generated at a shallower depth in regions with increased heat near the surface

In a mature ocean, where are most sediments accumulated?

Subsurface water sourced from water trapped in the sediments during deposition is called:

An absorbant will absorb refrigerant when heated and release it when cooled.

Leaks in ammonia absorption systems are found with bubble leak tests.

An absorption system that uses waste heat from another industrial process is called a(n) ____.

In a double-effect absorption system, all of the heat released in the condensation of the refrigerant is transferred to the cooling water.

If a white precipitate forms in a solution of anhydrous ammonia and distilled water, more distilled water should be added until it clears up.
