Glimpse of Oceanography

Oceanography is the study of the ocean, the ocean floor, and the air over the ocean. Ocean, which is also often called the ocean, is a large body of water. Together, the waters cover nearly three-quarters of the earth's surface. Scientists, engineers, and technicians who study the oceans called oceanographers or oceanographer.

Oceanographers very important job. Humans rely on the ocean to get fish and other foods. Just like the land that has become crowded and polluted, the oceans have become more polluted and overexploited. Oceanographers are trying to understand what controls the fish stocks and help the government decide how much fish can be caught each year.

The oceans help determine weather what will happen in the world every day. The oceans also affect Earth's climate. Climate is the weather that occurs over a long period. Changes in ocean temperatures and ocean currents have a major effect on climate. They can help us understand the global warming caused by the greenhouse effect.

Study the seabed to provide information about the past of the earth on the scientists. Sediment or mud on the seabed containing the remains of plants and animals living in ancient seas. It includes ash from the eruption of an ancient volcano and record disasters in which an asteroid crashing into our planet, killed the dinosaurs and other life. Seabed also provide information to scientists about the causes of earthquakes and earth structures.
