EVERYDAY SCIENCE

Detailed explanation-1: -To accomplish their work, they may use field observations, computer models, or laboratory and field experiments. Chemical oceanographers and marine chemists study the composition of seawater, its processes and cycles, and the chemical interaction of seawater with the atmosphere and seafloor.

Detailed explanation-2: -Seafloor. Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean-and some of the deepest natural spots on Earth.

Detailed explanation-3: -Physical oceanographers study the relationship between the ocean’s physical properties, atmosphere, seafloor and coast. They investigate ocean temperature, density, waves, tides, and currents. They also focus on how the ocean interacts with Earth’s atmosphere to produce our weather and climate systems.

Detailed explanation-4: -Physical oceanography deals with the properties of seawater (temperature, density, pressure, and so on), its movement (waves, currents, and tides), and the interactions between the ocean waters and the atmosphere.
