1.ocean surface currents are produced in the top 400 m surface of the ocean surface by the winds. Ocean surface currents produce gyres in the oceans. In the northern hemisphere oceans gyres move clockwise whereas it move anticlockwise in southern hemisphere oceans.
dark blue 0.0-0.28m/s
light blue 0.28-0.44m/s
green 0.44-0.56m/s
yellow 0.50-0.72m/s
orange 0.72-0.80m/s
red 0.80-0.92m/s
Dark red 0.92-1.0m/s
3.There are some events and activities that take place in one part of the globe will affect our region. It can be natural or manmade. Eg. If the melting of polar ice sheets due to global warming will affect our region also and can result in rise in sea level and subsequent submergence of low lying areas. Other natural activities like volcanic eruption in other parts of the world which causes dust and other particles to cover the sky and blocks the sunlight in reaching the earth will cause the reduction of temperature in our area. Similarly atmospheric phenomenon like El Lino La Nina in other parts of the world will affect our region also.Some man made activities like burning of fossil fuels on a large scale, deforestation disturbs the ecological balance of CO2 and will lead to global warming experienced in our region also.
4. the activities like burning of fossil fuel in our area will affect the other parts of the world. Also deforestation due to the growing demand of timber, medicines, food for the growing population in our area and raw materials for industrial growth will affect the other regions of the world. Also natural disasters like earthquake, volcanic eruption in our area will affect the other parts of the globe.
6. Since unregulated disposal of wastes, chemicals in the ocean degrades its quality and affect the marine life. So strict international laws have been designed to protect the ocean from the waste being dumped carelessly and thus minimise its adverse affect on human health and marine environment and efficiently use the ocean in fishing and navigation. These international laws were necessary to codify the use of territorial waters, sea lanes and ocean resources. These laws were necessary to prohibit illegal activities like serious pollution, smuggling, spying, weapon testing are stictly prohibited. With the help of these international laws the ocean resource like minerals, fishing are divided among coastal countries to regulate the exploitation of the ocean resources. These laws extend not only to other neigbouring countries for the distribution of ocean resources among these countries but also to other countries who are navigating in the ocean.
