Oceans: Physical, chemical and biological characteristics

Volcanoes and sea-scarps. This great variety of relief is largely due to interaction of tectonic, volcanic, erosional and depositional processes. At greater depths, the tectonic and volcanic phenomena are more significant processes. Continental Shelf: This is a gentle seaward sloping surface extending from the coasts toward s the open sea. In all, about 7.5% of … Read more

However, the current rate of change is unprecedented, driven by human activities that are altering the delicate balance of our planet’s atmosphere. This rapid warming, known … Read more

Movement of Ocean Water

The movement of ocean water is a complex process that is driven by a variety of factors, including the Earth’s rotation, the sun’s energy, and the gravitational pull of the moon and the sun. The movement of ocean water can be divided into two main categories: waves and currents. Waves are caused by the wind … Read more
