EVERYDAY SCIENCE

Detailed explanation-1: -In general use, the term “earth science” often includes the study of the earth’s atmosphere (meteorology or atmospheric science), the water flowing on and beneath the surface of continents (hydrology), and the earth’s seas and oceans (oceanography or ocean sciences).

Detailed explanation-2: -An oceanographer studies the ocean. Oceanography covers a wide range of topics, including marine life and ecosystems, ocean circulation, plate tectonics and the geology of the seafloor, and the chemical and physical properties of the ocean.

Detailed explanation-3: -Information from ocean exploration can help us understand how we are affecting and being affected by changes in Earth’s environment, including changes in weather and climate. Insights from ocean exploration can help us better understand and respond to earthquakes, tsunamis, and other hazards.

Detailed explanation-4: -The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into four distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans.
