Abiotic factors
Some Abiotic factors include: sunlight, natural disasters, water contents, and tides.
Sunlight:
When sunlight hits water, part of the light gets absorbed and part of it gets reflected. Sunlight appears to be colorless, which we call white light, but it's actually made up of all the colors of the rainbow. Blue light is absorbed by water at a slower rate than other colors of light. Pure water is also said to naturally be a faint turquoise color, but it is only visible when there is a lot of water in one spot - like an ocean. These two factors combined make for the spectacularly blue water you see at beaches around the world.
Natural disasters:
Some of the most common natural disasters in the indian ocean include:
- Tsunamis
- earthquakes
- water tornadoes
- typhoons
- cyclones
Water contents:
Why is the ocean salty? As water flows in rivers, it picks up small amounts of mineral salts from the rocks and soil of river beds. This slightly salty water then flows into the seas and oceans. Ocean water evaporates through the process of the water cycle, but the salt doesn't evaporate and remains dissolved in the ocean. As time passes, the remaining water gets saltier and saltier.
Tides and Currents:
The indian ocean experiences both tides and currents that vary depending on time or day or year.
The tides are caused by the gravitational pull of the sun and moon and the forces weaken as distance increases.
Ocean currents are a continuous directed flow of ocean water capable of traveling thousands of kilometers. Surface currents move water at the surface of the ocean, while submarine river currents flow deep below. Ocean currents can significantly influence the climate of coastal areas and can also impact the life cycles of certain marine creatures.
