Fractures create weaknesses in rocks, which are then exploited by tropical chemical weathering i. We went for a hike in Parque Nacional da Tijuca which is part of this Atlantic rain forest that surrounds Rio de Janeiro. Wandering around you can tell how these steep valley floor due to the sugarloaf-domes ramparts forests are more diverse and have rich supplies of water and soil to support the thick, full tree canopies. The sugarloaf-domes also support summit and shoulder forests, which are isolated and perched on high steep slopes.
The environment there is harsh with little soil, nutrients or water but allow host to a vast array of specialized vegetation. Rio de Janerio is definitely worth a visit, and I would love to return one day. It is a city of rich beauty, but of course also lots of underlying poverty. To be able to learn a bit more about the foundations and formations of such a spectacular place makes it all the more rewarding for me to enjoy!
Thus ends my travel trip in Brazil with my sister. You can check out her final video of Wild Nights in Rio , we missed the carnival but there is always good times to be had in Rio. Thanks for reading! Thanks for sharing, Stephanie. Interesting post as usual, keep exploring, working and keeping us informed. Bless you and please be safe out there. Nice blog, sounds like you had a blast. Hey, thanks for that. I should have checked this, it was the Cretaceous Period and I amateurishly wrote the upper limit.
I fixed it now, though it still is very vague which I apologize for! I live in Rio, also interesting in mountain formations and I can tell you, there are so much more to see! How can I be sure? Hope that helps, cheers! Thanks for enlightened me, staphanae. Because there was a question asked in my exams about how the peaksystem of rio r formed and which type.
Hi stepanie : Just wanted to say thanks for this…I always wondered how the peaks of Rio were formed. Very simple to understand, I also light the graphics. Great job. Does mathematics carry human biases?

The ground level may drop over thousands of years as sediment surrounding the rock is washed away by flooding or blown away by the wind. This occurs more often in the desert where there is little vegetation to protect the ground from erosion.
Bornhardts are normally surrounded by flat plains. They are often found in the desert, but can also be found in many other climates. A bornhardt in a tropical or other location may indicate that the region was at one time a desert in the past. Cable cars carry people to the top of Sugarloaf Mountain for a view of the city. Sugarloaf is also famous for rock climbing. There are also two other large rock formations in the city with access by cable car and rock climbing routes above the city.
In the country of Namibia in southern Africa, a group of granite bornhardts called the Spitzkoppe are found in the Namib Desert. The highest rises feet above the desert floor and the granite has been estimated to be million years old.
The art of local bushmen is found on the rock formations at Spitzkoppe. Kata Tjuta, sometimes called Mount Olga, is the highest of another group of bornhardt rock formations in the Northern Territory of Australia. They are composed of a mixture of granite and basalt with sandstone over the surface.
There are 36 dome-shaped rocks, including Kata Tjuta at nearly feet above the surrounding plain. A bornhardt is a rock formation with steep or vertical sides and a round or dome-shaped top.
