A ocean contains about 120 million tons of salt! A ocean can be polluted many ways such as people littering, oil spills,or other bad stuff. A ocean can help humans a lot we can easily clean out the water from its salt and pollutants then we drink it. The ocean has the largest population of animals in it. Some animals aren't even known yet. If the ocean gets harmed with oil spills or lots of litter, it can affect us because the ocean supplies us with lots of our food. I also know that winds can create currents. Current are the direction the waves move in.
SP4: Analyzing and interpreting data
In class we had a worksheet on a Lego Spill and had to figure out what currents brought them to certain places using coordinates. So most of the legos ended up on a coast. I think the coast line was the California current.
