Coral's Role
How the formation of coral can tell us about its past.
Coral is a special type of animal called an invertibrate, that lives in the ocean. This means it does not have bones like people do. So, as the young coral grows it forms a shell around itself to support and protect its soft body. This shell is made up of many different elements that differ based on its enviroment. When temperature change so too does the ratio of elements in its shell, in this case the Strontium to Calcium. When the coral dies it leaves behind this shell and its contents. Scientists can gather this shell and test it to discover the ratio and get an idea about the climte it grew up in. To learn more about the process invloved click on the link below!

Climate and the Future
The flow of the climate and the direction that it is heading toward is important for all of life on earth. This obviously includes people too! Right now many scientists hard at work trying to predict the way the climate will go by looking at what is has done in the past.
- Coral can play an important part in discovering the past climate and predicting the future our our world. This effort to uncover the past through experimentation is called Paleo(meaning old)modeling.
