3. (5-7 sentences) Would it be easier or more difficult to locate a sunken plane in salt water,  fresh water, or quicksand? Explain your answer using density concepts.  Think about what it would be like to lower and raise a submarine or plane in these fluids.  

It would be more difficult to find a plane if it sunk in quicksand because quicksand has a much greater density than freshwater and saltwater since its both a mixture of water and sand, so it would be very difficult for a submarine to resurface. Although, an object, like a submarine, sinks quick in quicksand because of its great density. Even so, escaping quicksand can be very difficult, so bringing an airplane back up to the surface will take some time, unless of course scientists used a powerful crane. Next off, saltwater is less dense than quicksand but more dense than fresh water because it has more mass from the dissolved sand in it, as the names says. Freshwater would be the easiest liquid to recover the sunken airplane because its density is less than saltwater or quicksand’s, so freshwater is the best liquid to lower and raise a plane using a submarine. In conclusion, the most difficult substance to retrieve a sunken plane is quicksand for it being most difficult to escape and making the object sink down the more pressure and escaping; saltwater next, and freshwater being the easiest as it is an all liquid with less density than the other opposing liquids.
