Grand Canyon

Good afternoon friends,

Today I am going to present a little bit of a fieldwork I did in the Grand Canyon (USA).

  Geology and slope strongly influence the formation of Grand Canyon soils, so they are classified as underdeveloped. The soils are highly variable, ranging from the soils of the humid forests of the Northern Rim to shallow. The Grand Canyon is formed by several layers of sandstone, schist, limestone, and so on. Erosion, mainly by water (and ice) and second by wind, were responsible for carving the Grand Canyon. Other forces that contributed to the formation of the Canyon are the course of the Colorado River itself, volcanism, climate variations. The Grand Canyon National Park, near the city of Flagstaff, I consider the most interesting place to visit because there is a geological museum and guides available to explain about the origin of the place.

I hope you enjoyed. I'll post more information later.

The birth of our project

Hello guys! Starting the activities of this blog, nothing more fair than a presentation about who we are and what we want! The research project on Soil Education, started in the Department of Geography of USP, under the initiative of Prof. Dr. Déborah de Oliveira in 2010. At the beginning there was only one student who started the research, in 2011 another 3 students joined us, constituting our group. Soil education is often forgotten in schools, or treated in a simple way, which can generate students disinterest. We will disseminate in this space the results of our research, guidance to teachers, experiments and exchange of experiences for soil education, after all it is a finite natural resource, as many others that must be respected and preserved. Beyond academic research we want to disseminate and make accessible materials and teaching methods that help teachers, students, and even other researchers in Soil Education. We will do this by addressing the subject of soil in a

WHAT IS SOIL? Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. It forms at the surface of land – it is the “skin of the earth.” Soil is capable of supporting plant life and is vital to life on earth. Soil, as formally defined in the Soil Science Society of America Glossary of Soil Science Terms, is: The unconsolidated mineral or organic material on the immediate surface of the earth that serves as a natural medium for the growth of land plants. The unconsolidated mineral or organic matter on the surface of the earth that has been subjected to and shows effects of genetic and environmental factors of: climate (including water and temperature effects), and macro- and microorganisms, conditioned by relief, acting on parent material over a period of time. So then, what is dirt? Dirt is what gets on our clothes or under our fingernails. It is soil that is out of place in our world – w
