Tides and Diversity on Tides
Tides: Tides are the rise and fall of sea levels in comparison to the reference mean sea level (MSL). They are caused majorly by the combined impacts of the gravitational forces of the Moon and the Sun, and the rotation of the Earth. Most coasts experience two nearly identical high and low tides every day (semi-diurnal tides), while other coasts have one high and low tide every day (diurnal tides). Tidal phenomena are not limited to oceanic water but can occur in terrestrial (land) and other aquatic systems too. Though the changes are not as evident as the sea water’s movement
The Continental Shelf is a part of the Earth’s crust (Continent) that is submerged under an area of comparatively shallow water (Shelf Sea). Although geographically it seems to be a part of the deep-sea, it is physically just the flooded seabed contiguous to the shores of the country to which it belongs.
The shallow area of water near the continent, between the shelf and the abyssal plain (oceanic bed), is called the continental margin. It comprises the continental slope surrounded by a flatter continental rise. In some places, the continental shelf's physical, chemical and biological character change drastically as it abruptly transitions into the steeper continental slope. The increased available sunlight in the continental shelves supports more diverse lifeforms, in contrast to the darker abyssal plains which have sparse life
