Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.
How sea waves are generated?
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. The gravitational pull of the sun and moon on the earth also causes waves.
What are the characteristics of the marine ecosystem?
Specific marine ecosystems such as coral reefs, estuaries, salt mashes, mangrove forests are found throughout the world, but are characteristic of certain areas, depending on climate, geography, water temperature, and other physical factors.
What is an ecosystem ocean?
Marine ecosystems are among the largest of Earth’s aquatic ecosystems. Examples include salt marshes, intertidal zones, estuaries, lagoons, mangroves, coral reefs, the deep sea, and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content.
What are the oceanic factors of global weather?
The Earth’s weather patterns, which consist of different conditions of temperature, precipitation, humidity, wind, air pressure, etc., result in various climate zones across the globe. Weather and climate are the result of the transfer of energy from the sun at and near the surface of the Earth.
