What phyla are responsible for red tides?
Estuarine, marine, or fresh water algae is responsible for toxic red times. The algae accumulates rapidly in the water column discoloring the water's surface.
What are red tides caused by?
Red tides are a natural phenomenon caused by an increase in the amount of nutrients that algae need usually due to farm runoff. When the amount of nutrients reaches a certain level there is a significant increase in Karenia Brevis algae. Many also believe that red tides occur when there is a combination of very high temperatures, wind, and rainfall.Red tides is mostly caused by the increase of temperature and the difference of temperature between hot surface and a cold layer beneath the hot surface. When it is night, the dinoflagellates move to the cold layer to absorb nutrients. When it is day, they move to top to photosynthesize.Red tides are caused by algal blooms. Certain types of algae in the ocean multiply at rapid rates, typically by excess nutrients found in the water. The algae die and the decay process consumes the oxygen in the water -- one of the reasons these red tides are so destructive.By the way, not all algal blooms are red. It all depends on the algae present which grow quickly.A bloom of red algae, usually due to increased nutrients in the water.These extra nutrients can come either from natural sources or human caused pollution.The red algae both deplete oxygen in the water and produce toxins, which kill fish and other sealife. The toxins can also kill people if they eat seafood (especially filter feeders e.g. clams, mussels, oysters, scallops) caught during the period of the red tide or immediately afterwards.
What factors can make tides vary even in places that are close to each other?
the moon's revolution around the earth has a major impact on the tides. the sun also has a less great impact on the tides, too. if we had no moon the tides would change greatly
How is a tidal range affected when the moon earth and sun are in line?
Spring tides occur in principle when the three objects are lined up so that the gravitational forces of the Sun and Moon are combined. In practice in many places the spring tides occur 1-2 days later. Tides are a proximity effect, which means that the Moon's effect on the tides is the major effect because it's closer, while the Sun's overall gravitational force on the Earth is much stronger. Tides happen because the Moon's gravity is much stronger on one side of the Earth than the other, because it's close, while the difference is not so much with the Sun's gravity because it's a lot further away.
What did Isaac Newton say sbout tides?
the moons gravity pulls on the ocean water as the earth revolves on its axes, causing tides
Are red tides always red?
No, red tides are usually red but can be yellow and purple
When was Red Silent Tides created?
Red Silent Tides was created on 2010-09-17.
Why are red tides called red tides?
Because of a bunch of algae that turned red and make oysters poisonous to eat.
How are protists diffrent from bacteria?

How red tides occur?
its caused by the moon
Why are red tides often red in color?

What class of mollusks are affected by the red tides?
oranges
Blooms of dinoflagellates are often called what?
red tides
What is an example of spring tide?
Trololololoolol
What group of protists cause toxic red tides?
Dinoflangellates.
Is it true blooms of dinoflagellates can cause red tides?
Yes, they can.
What is red tides?
Red tides are caused by the overgrowth of certain types of algae. Red tides are toxic, killing marine life as well as making humans who have eaten seafood which has been in the contaminated water sick.
