The comparison Between the Vredefort Dome and Pilanesberg.
1 Introduction
The Pilanesburg and Vredefort Dome are two similar landforms that have different igneous activities. These activities gave the landforms their circular shapes. In this essay there will be a geomorphologic comparison between these two landforms highlighting the similarities and differences in appearance, structure, location, geology and climate.
2. The Description of Pilanesburg
The Pilanesburg is found in the North West Province. It contains a number of hills. These hills (valleys) form a perfect circle and consist of different rock types. Grab & Knight (2015:43) states, “The height of Pilanesburg ranges from 100-500 meters”.
3. The Description of Vredefort Dome
Grab & Knight (2015:31) states, “the Vredefort Dome is found in the northern part of Free State, the southern part of the North West and in the Gauteng Province”. The asteroid formed a huge crate, as the crate was eroded, it left the geomorphological landform which today is known as the Vredefort Dome. Grab & Knight (2015:31) support this argument. It is circular at the top and has the vertical section that is exposed on the earth surface.

At the Vredefort Dome, only half of the dome is exposed to the earth surface because the Karoo super group hides the southern part of

These craters were formed differently as the one that gave rise to the Vredefort Dome was formed when the asteroid hit the earth surface and the Pilanesburg was formed after the volcanic eruption. Linda & Elkins-Tanton (2006:84) supports this statement. As these craters were eroded, they gave rise to the Vredefort Dome and the Pilanesberg. Both of these landforms were formed approximately 3000 million years ago (Grab & Knight, 2015:32). Both landforms are recognized as geotourism. Today both landforms remain circular in

Yes this feature is the result of erosion and depositional processes however, it is not associated with the current water course. This feature may be the result of a Gilbert type delta that once occupied this area. Gilbert type deltas have three main components; topsets, foresets and bottomsets. Topsets are fluvial sediments (primarily sandur deposits) that were deposited on the subaerial delta surface. Erosive events occurring on the upper forslope can result in downslope channels and chutes. These features are then eroded by either strong currents or by debris flow resulting in these channels and chutes to become filled. Foresets are a combination of sand and gravel facies. The are deposited by gravitational processes on the delta foreslope and the grains tend to become finer and more angular downslope. Bottomsets consist of fine grained silts and clay and are deposited at the foot of the delta front.
Kaiserwald was built in March of 1943, it was a concentration camp ran by the Nazis, outside Riga in Latvia. Kaiserwald started out as a camp for German criminals. Eventually, any Jews found on Latvian soil were put into Kaiserwald. (Kaiserwald Concentration camp Jewish virtual library)
Brunelleschi 's Dome: How a Renaissance Genius Reinvented Architecture, written by Ross King, describes the history of the city of Florence and life at the end of the Middle Ages through the genius of Filippo Brunelleschi. The book begins by giving information about the historic competition that led to the impressive dome that sits atop Santa Maria del Fiore. It then gives an account of the history of Florence in the late 1300s and early 1400s and the building of the cathedral and the initial competition for the dome 's design. After providing information about Florence and the cathedral, Ross King gives background information about Filippo Brunelleschi, his experiences as an artist and scientist in both Florence and Rome, and insight into

Pilsen bloomed from its early start in the late nineteenth century by German and Irish immigrants, followed later by Czech’s, also known as bohemians. (Mead-Lucero.) This boom was caused by the Southwestern Plank Road, which was a major trade route in construction at the time. (Pilsen.) The Czechs adopted the name Pilsen from a city in the Czech Republic known as “Plzen.” (History of Pilsen and Little Village.)

Palaeogeography deals with the reconstruction of physical geographical conditions for the eras of the Earth's history. The term comes from the Greek παλαιός (palaiós) meaning ‘old’ and γεωγραφία (geōgraphía) meaning ‘a description of the earth’ and seems to have been introduced in the Earth sciences vocabulary as ‘Palaeo-Geographie’ by Ami Boué (1794‒1881), a French‒Austrian geologist, in his publication Einiges zur palaeo-geologischen Geographie (Boué, 1875, p. 2). Palaeogeography focuses on the distribution of land and sea, the spread of mountains and volcanoes and the expansion of glaciations, among others. The results are presented in geographic depictions called palaeogeographic maps. A special kind of palaeogeograpahical map is palaeobiogeographical maps depicting the distribution of

Later after the sea finally retreated occurred volcanic activity. Mountains rose through laccoliths, which also resemble volcanoes. These laccoliths differ in that they do not erupt. They shifted layers of rock upward in the shape of a dome. This specific piece of geologic morphology occurred at the end of the Cretaceous time. This marked the beginning of the Laramide Orogeny, which was a well-known period of mountain formation in western North America.
The Pazzi chapel marked a momentous return to classical rudiments. It has a central dome "reminiscent of the lines of Rome's Pantheon" (Cunningham 274). It has an oculus just like the Pantheon. Furthermore, although smaller in scale, the dome of the chapel is also hemispherical in shape and austere in design. Likewise, the chapel's twelve-ribbed dome approached the floor below it in the same respect as the Pantheon; completed after Brunelleschi's death, the chapel dome caps a severe rectangular base in the same way the Pantheon dome covers an ascetic circle. (Tractenberg). The chapel's dome, however, is itself capped with a cylindrical cupola "with delicate lantern" added in 1462 (Italy Field Study). Although they differ in base, both domes were framed according to circles. The image above illustrates the resemblance between the Pantheon's and Pazzi chapel's dome. The image on the left is the architectural plan of the Pazzi Chapel. The one on the right is that of the Roman Pantheon. If one is to draw a near perfect circle that fills the interior of the dome, as...
Most big asteroids are ball shaped. Smaller asteroids, which are usually broken off of a larger asteroid, come in a lot of different shapes. All asteroids have craters that form when they bump or crash into other asteroids. The older the asteroid, the more times it has been hit and the more craters it has.
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
