What causes red tides ?

What  causes red tides? Why crimson seas are not as unbelievable a sight as you might first think.... A red tide is the rapid accumulation of a mass of aquatic algae, made up of mobile single-celled microbes, known as dinoflagellates - meaning the nature of tail-like projections spreading them through water. Due to 'whipping whip'. Algae grow, or blossom, more rapidly than usual to consume more nutrients that have suddenly increased from the cool depths of the ocean below. The red color is down to the presence of a certain species of dinoflagellate, or phytoplankton. With more abundant diatom algae, dinoflagellates make up the majority of the plankton of the ocean. Despite the rather staggering appearance of a sea that has turned red, many algal flowers are actually completely harmless. However, you should not consume seafood after red tide as some phytoplankton may release harmful substances into the water. Some dinoflagellates can produce toxins when eaten ...

What is coral ?

What is coral? Is  it  animal, vegetable or mineral? While corals may look like reefs and share many characteristics of plants, they are actually animals. To be precise they are aquatic marine invertebrates (known as polyps) that live in warm shallows of clear coastal waters located around the world.  A large number of marine organisms make their home among the corals, making them the most abundant and diverse habitat on Earth. Because the nutrients that the plankton needs to feed on are better dissolved in deep, cold water, warmer layers become less attractive places to capture large numbers of floating plankton. Therefore, the upper shallows remain warm and clear - ideal living conditions for micro-algae, who use sunlight to combine carbon dioxide and water to create their own food source, which they use with their coral Share. Corals remain in partnership with single-celled Zooxanthella algae, which are also responsible for the bright colors. If the al...

Why does water turn white?

Why does water turn white? Discover which part of the course of the river provides the setting for some of the world's most dangerous turbulent waters. White water is in the upper part The course of a river when the gradient and obstructions distract the flow of water, causing it to churn and create bubbles. These bubbles leave the ect behind, which collides with light, making the water appear white. Whether a river flows smoothly depends often on its speed, and along the banks of the Steppard River, faster water will flow. The flow becomes turbulent due to a combination of obstacles such as fast flowing water and rocks, with unexpected variations in search speed and direction that provide the setting for some of the world's most dangerous turbulent waters, part of the course of a river. . Water turned white? Water. This produces many different characteristics in the river. Where the water doubles back on itself, there are open pockets with bubbles; These ...

What is the coast eroding?

Why is the coast eroding? Learn about the amazing processes that are building and breaking our shores right now…. Water is not given enough credit for its role in shaping the Earth. Tectonic plates and volcanic eruptions are often cited as the culprits for most land characteristics, but it is the water and wave action that shape the beaches of our world.  When a wave crashes on shore it carries sediment that gets suspended in water, and it also pushes large sediment along the ground. When a wave is heard it also carries the sediment with it, but rarely at a uniform rate.  If a wave accumulates more sediment then it goes away, then it becomes sediment, which expands the coastline. Conversely, when more sediment is being removed than added, the coastline is reoriented or destroyed. Coastal erosion today accounts for the most amazing landforms in Australia from the Twelve Apostles to the White Cliffs of Dover, England. The type of coastline form...
