its body was acclimated to the extra pressure of water above its habitat. When it was brought to the surface very
quickly, the gases in its body experienced much less pressure so they expanded,
resulting in its bloated look, and caused it to die.
27. Evaporation will result in greater salinity
of the water left behind. This water
will then become denser and could begin to sink to a lower level in the ocean. A drop in temperature will do the same thing,
because colder water is denser than warmer water.
28. New oceanic crust is formed at the ocean
ridges, where plates are moving apart.
The
29. The surface layer is a well-mixed layer
exposed to wind and currents and is generally warmer in temperature. The deep layer is uniformly cold and much
thicker than the surface layer. The
thermocline separates them and is a transitional zone between them.
30. The differences between these types of crust

basalt and is denser and thinner than continental crust, which contains
granite, is less dense, and is thicker.
