A Visibility (how far you can see underwater). The nature and composition of particles in the water affects visibility. Large, heavy material - like from gravel and rock bottoms - settles out of the water quickly, restoring visibility quickly. Small, light particles - like from mud and clay bottoms - can remain suspended for very long periods. See Being a Diver III - Visibility. - answer30) What the bottom is made of can cause big changes in A visibility (how far you can see underwater). B temperature (how warm the water is). C current (the movement of water). D buoyancy (whether you sink or float). D Trying to defend themselves. Nearly all aquatic life injuries result from defensive actions by the animals. You can generally avoid injuries by being aware and respectful of aquatic organisms. See Being a Diver III - Aquatic Life. - answer31) Most injuries caused by aquatic animals happen because the animals are A hungry. B curious. C injured. D trying to defend themselves.
