PPT-Marine Sediments

Presented by Derek Lumary Rudy Marmolejo Jazmin Quijada What is a Marine Sediment Why are they important Marine Sediments are particles of organic or inorganic origins that . These sediments come from the cast iron water mains we have in our network Normally this doesnt aect anyone But a burst water main for example will increase the water ow and can stir up the sediment causing the water to become discoloured Occasional Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles.
