differences between oceans and seas

Seas and oceans are two large water areas that cover vast areas of the Earth's surface, but they differ in many aspects. Here are some differences between seas and oceans:

1- Area: The oceans cover a much larger area than the seas, as the oceans make up about 71% of the Earth’s surface, while the seas make up about 29%.

2- Depth: The oceans are much deeper than the seas, as the average depth of the oceans is about 3,800 meters, while the average depth of the seas is about 200 meters.

3- Density: Because of the difference in the degree of salinity, the density in the oceans is greater than the density in the seas.

4- Weather conditions: The seas are affected by weather conditions more than the oceans, and the surface waters in the seas are more volatile because of this.

5- Marine life: Marine life varies in the seas and oceans. The oceans include more diverse and larger species of marine animals such as whales and dolphins, while the seas include less diverse and large species.

6- Climate: Climate patterns differ in the oceans and seas, and the oceans are affected by stronger winds and currents because of their larger size.

7- Seismic movement: the oceans are more exposed to seismic activity due to the presence of continental plates under the oceans, while the movement of continental plates in the seas is more calm.

8- Pollutants: The oceans are more exposed to pollution due to plastic and oil waste, while the seas are less exposed to pollution.

9- Uses: The oceans are used more for commercial fishing and shipping, while the seas are mainly used for tourism and water sports.

10- Name: The seas are given certain names such as the Mediterranean Sea, the Red Sea and the Black Sea, while the oceans are given general names such as the Indian Ocean

11- Water sources: Water sources differ in the seas and oceans. Most of the fresh water in the world is found in the seas, but it is not suitable for drinking due to the high degree of salinity, while some sources of fresh water are found in the oceans, such as the rivers that flow into them.

12- Weather: The seas are affected more by bad weather such as hurricanes and tropical cyclones, while the oceans are affected less by their larger size.

13- The geological structure: The seas and oceans differ in their geological structure. The oceans contain underwater forested mountains and active volcanic craters, while the seas are calmer and contain few mountains and volcanoes.

14- Human activities: The seas and oceans are greatly affected by human activities such as overfishing, pollution and global warming, but it is believed that the seas are more affected by these activities due to their high surface temperature.

15- Vegetation Cover: The vegetation cover varies in the seas and oceans. In the oceans there are algae and other types of marine plants that live in the depths of the water, while in the seas there are seaweeds, coral reefs and other aquatic life.

16- Economic importance: The oceans play an important role in the global economy, as they are used in commercial fishing and exploration for oil, gas and minerals. The oceans constitute major trade routes, while the seas constitute an important resource for marine resources and tourism.
