Recommended: Essay on the demise of the reef
What was the reason for corals disappearance between 1996 and 2012? Was it other animals, humans, or maybe the water. Well the answer to that big question will be told but first I will tell you how the scientist discovered the answer using the scientific method. At first scientist made an observation. The scientist realized that corals have been dying and they got curious so they looked into and got onto that subject. After they got curious they did what any curious person does, ask questions. The scientist would ask questions like “Whats wrong with the corals?” or like “Why are so many corals dying?”. When they asked the questions they of course made a hypothesis next. They made an assumption of what was wrong in which this case the assumed

The process of scientific inquiry begins with the motivation to uncover the answer to a question. It then requires extensive research to gather all the information that could possibly be useful. Finally, one must put all the pieces of the puzzle together to make sense of all the information gathered and interpret it to answer the question. The last step is to write out what has been learned and publicize it to spread the new knowledge. There are many other factors, however, that also come into play in the process of scientific inquiry.
This website gives a large historical overlook and possible conclusion to the issue of coral reef bleaching. Since the 1980’s episodes of coral reef bleaching and death have occurred almost every year in one or more of the world's tropical or subtropical seas. Bleaching happens in episodes, with the most severe typically accompanying coupled ocean–atmosphere phenomena. Bleaching episodes have resulted in loss of coral
First, when observations are made, hypothesises are formed. To test these hypothesises scientists conduct experiments. If their hypothesis is right, it is confirmed by further experiments and validated by other scientists. After many experiments and confirmations, a theory is formed. A scientific theory is a broad and general idea or explanation provided by scientists and is related to observations and is supported by a large amount of evidence. A theory is not a fact however it is just a possible explanation. An example of a theory is the Big Bang Theory.
Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people.
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
Scientific theory by definition seeks to explain observed phenomena by stating the causal reasons that led to the event. The central component of the theory must adhere to the principles of
Another point explicitly stated in the film was that corals didn’t really have a life expectancy. However, because of climate change, they die early. It was discovered that some corals were turning white after six months which is definitely fatal to our planet because we may witness the eradication of an entire ecosystem in our lifespan as said by Doctor Ruth Gates. In addition to this, there is a big heat wave travelling near the planet which leaves dead corals in its trail and in 25 years, all of the world’s corals wouldn’t be able to keep up with this heat and they will all eventually
Peter Mumby found corals that were alive in the Rangora lagoon. In the video that we watched in class the video showed that there were not a lot of corals alive. But this is good news because with alive corals it should back more alive corals to the ocean. Peter Mumby found olive-green porties corals. Those corals were about the size of hippos. Corals started dying in 1998 because of a heat wave. Heat waves raise temperatures of the Ocean. The corals can not live with how hot the ocean is that is why they die. Heat waves cause corals to die is what it said in the video we watched in class. Mumby predicted that it would take the corals over 100 years to recover from the heat wave. The heatwave in 1998 killed
Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse. Unfortunately, human impact has resulted in long-term stresses that, unlike the short-term stress of natural disasters, coral reefs are not as capable to recover from. “Approximately half of the world’s coral reef ecosystem resources are considered by scientists to be in 'poor' or 'fair' condition and have declined over time due to several anthropogenic threats” (“Status of Corals” par. 2). Through poorly administered commercial practices, carelessness and ignorance among the common people, and human aggravated natural processes coral reef destruction has become a serious issue afflicting the world’s biodiversity and it’s intricate biosphere mechanics (“Human Impact on the Great Barrier Reef” 1) (“What Are Coral Reefs?” 1).
Science is an approach by which scientists relate things to each other and explain the main concepts that govern the very laws that they derive. [Gauch, 2003]
CORAL REEFS Almost every one of us have heard and most of you have seen the Coral reefs but did you know what actually these are: As a mariner its important to know about the marine life, that was one reason I have chosen this topic for my today’s short presentation. GM, my scheme of presentation will be flashed.

A scientific theory is an explanation that is well- substantiated explanation in regards to some aspect of the natural world that is attained through scientific method and is tested numerous times and usually confirmed through vigorous observation and experimentation. The term theory can be seen as a collection of laws which allow you to show some kind of phenomenon. The strength of a scientific theory associated with the diversity of phenomena can explain its elegance and simplicity. However when new evidence is gathered a scientific theory can be changed or even rejected if it does not fit the new findings, in such cases a more accurate theory is formed. Scientific theories are used to gain further
In conclusion, I would like to say that before writing this paper, I had no idea how important coral reefs were to the earth. I have learned a lot and I think that if more people were informed about the positive capabilities of them, humans wouldn't be so careless about them.
Science is the history of using systematic methods of study to make observations and collect facts. It covers fields of knowledge that deal with a variety subjects. The word science comes from a Latin word which means “knowledge”. Some scientists search for clues pertaining to the origin of the universe; others examine the structure of molecules in the cells of living plants and animals. Scientists investigate why we act the way we do, or try to solve complicated mathematical problems to explore the working of the world. Theories developed by these scientists cannot be accepted as a part of scientific knowledge until it has been verified by the studies of other researchers. It has to repeatedly tested and found to be true.(pg. 366-Ency brit)
