The studies about the tectonic plates movements and climatic changes are crucial for our life on Earth.
It's not only a simple planet, but a living world, a world in continuous movement, thus, continuous changes. It's also a fragile world that needs care. It's the only living world ever known. Detail is essential.
By studying how physical and climatic events affect this living world, we can learn how to deal with its fragile equilibrium.
Life takes numberless years to emerge. Some changes, too.
Now picture a very small insect that lives in a tree. Its life cycle lasts only two weeks. If that little insect is a summer insect, during its whole lifetime, it will have never witnessed any significative change in its home, like, for example, the winter's arrival. The same goes for the relationship among humans and Earth . That's why it's so important to have the help of new generations. The more we know, the more we'll be ready for the future. Fortunately, insects know how to act when winter arrives.
Brazil and earthquakes
Brazil is far enough from the edges of the South American tectonic plate:
Brazil is also on an area where the plate has a thickness of about two hundred kilometers, and, therefore, high-intensity earthquakes are absolutely rare. That doesn't mean that Brazil is safe at all, because there are many faults that leave it vulnerable to earthquakes, even though, if compared to other South American neighbors, with low intensity. Take a look:
