Science is a fascinating subject for any age, as the concepts are applicable in our everyday lives. There are several different categories related to science, including geosciences, life sciences and physical science. For the time being, we will talk specifically about the geosciences. The geosciences deal with the many different processes that take place on our planet. Geoscience is inevitable and omnipresent (which in many cases is part of its appeal). Below you will find some examples of specialities that deal with geoscience. You will find short definitions as well as some of the sub-disciplines that belong to this course.
Geology describes the land or rocky parts of the Earth’s crust and their evolution over time. Anything that naturally came from the ground is among the prospects of Geology. Among the most important sub-disciplines are:
- Mineralogy and Petrology
- Engineering Geology and Sedimentology
Geodesy and Geophysics
These disciplines study the shape of the earth. In concrete terms, this means investigating the Earth’s reaction to forces and their potential fields, which include both magnetism and gravity. Geophysicists explore science deep within the core and mantle of the Earth.
The wonderful scientists who have put in so much effort to learn about the underlying contents of our planet have saved millions of lives. How? By developing the means to detect strong earthquakes and tsunamis before the fully occur, that’s how! These men and women are heroes!
Soil is the outermost layer of the earth’s crust. A soil scientist investigates the processes of soil formation. Among the most important sub-disciplines are Edaphology and Pedology. We’ve learned so much about farming and cultivation techniques. The fresh, big vegetables and fruits that we have available today are likely better thanks to the studies done by soil scientists.
Oceanography and Hydrology
Geology describes the land and oceanography describes the ocean. This includes all marine and freshwater areas of the earth. The most important sub-disciplines are Hydrogeology and physical, chemical and biological oceanography.
The study of water has brought us new ways to improve filtration, as well as hydropower and many other useful technologies. Life as we know it would be quite different and much more difficult to manage without these scientific studies.
If you know what a glacier is, you can probably guess what a glaciologist would study (here is a hint: the icy parts of the earth). You’d be surprised how important this study is. Have you heard of global warming? For years people thought it was a sham. Now, as the ice caps melt and the ocean levels begin to rise, the need for an understanding of these things grows.
Glaciology requires a scientist to study several portions of the same glacier and study the structure as well as how they react under certain circumstances.
The Earth is more than just land and sea, it’s the parts we don’t see so well. Atmospheric sciences include the study of the gaseous parts (alias the atmosphere) of the Earth. The most important sub-disciplines are meteorology, climatology, and agronomy.
Our atmosphere is highly important and vital to our survival. Before we had a proper understanding of it, we didn’t worry about things like pollution, radiation, and the like. Now that we’ve messed up our atmosphere quite well, we’ve realized how much we need to protect it.
So you see that there is no place on Earth where you can go to escape science. It is in the ground we walk on, in the water we swim in, and in the air we breathe. Who wouldn’t want to know more about geosciences?!
Geosciences are not only interesting, but they can also be beautiful. You can involve your child more in geosciences by showing him the beauty of nature. Whether your child’s interests lie in finding shimmering rocks or mountain biking, there are ways to apply science to the things they like to do outdoors.
Geoscience is literally a worldwide science branch. There’s no end to what we can learn and this is just a single planet among a potentially infinite universe! Who knows what else there is for us to discover! All we can now is wait and see what turns up!
