How can ocean floor features be measured and mapped using current acoustical technology? How can ocean floor maps be used in the commercial, military, and/or private sector? With the current technology that we have today we are provided with information on how the ocean floor may look. A piece of equipment that is used out in the ocean to measure the ocean floor is the sonar stick, this sonar stick is has sound to it and once it hits the bottom of the ocean floor it sends up a sound. Ocean floor maps can help with many situations, with the military like a submarine, it let's us know how far we are to the ocean floor and where the enemy is. Having the ocean floor mapped out allows us to go discover what is there and watch out for dangerous courses ahead.  On the image below it lists some of the objects it lists is the continental shelf, mid-ocean ridge and the trench.

Sand

Sand is one of the many materials that have been appart of this planet for many years. In class, we have discovered the true size, color, and material of sand. There were eight different sands to be disvovered, Maui, Cancun in Mexico, the Bahamahs, Key West, Hampton Beach in New Hampshire, Dessert Island, Plum Island, and Klamath in California. There have been differences to each one no eveyone of them was the same. There are also similatities like some beaches were either clear/white/brown or had a mix, five of those beaches were rough and three of them were smooth. Maui and Hampton Beach are two different kinds of beaches and both are located in different places. Hampton Beach is in New Hampshire while Maui is located in the area of the Gulf of Mexico. Maui sand is really rocks and they are brown and smooth. Hampton Beach is white and somewhat clear with a rough texture, it also has more of a crystal look to it. it was clear to see what was the differences and the similarities after gathering the data.
