Natural stone arches are geological formations that occur when rock is exposed to substantial amounts of erosion , which over time forces the rock into the shape of an arch. Stone arches are among the most diverse of rock formations, not only because of the large area where they are known to be found, but also their complex ways of forming. Although many factors contribute to making natural stone arches so enthralling, one key role keeps and hones our constant attention: each and every stone arch every formed will fall. Despite the things we do know about stone arches, they are continuously changing and teaching us new things about them as well as the world around us.
All naturally occurring stone arches are formed by the selective erosion of rock, but the terms by which this can occur are massive. Among the most frequent types of formation are wave action and lava flow. During wave action, water crashes constantly upon the rock, effectively accelerating erosion while sediment carried by the water is extremely abrasive, removing bits of rock. When lava flow occurs, the outermost la...
The site visited on this day was informally known as the Bedrock Knob (NTS grid reference: 120 342). It is in an area where patches of limestone and exposed bedrock are common. The bedrock is part of the Preca...
Q: Use St Peter’s basilica and Donato Bramante’s Tempietto in Rome, in opposition to John Balthasar Neumann’s Pilgrimage Church of Vierzehnheiligen in Bamburg, Germany, to argue that a rational engagement with architecture is a more effective means to comprehend and understand architectural form.
Shown in the picture above is volcanic extrusive igneous rock known as andesite. They were imported here to Laguna Beach to help minimize erosion (Merton Hill, p. 10-11). Extrusive Igneous rocks are formed on Earths surface due to lava quickly cooling or mixing with different materials such as ash or cinders from an eruption. There are two different types of extrusive igneous rocks; Plutonic and Volcanic. Andesite is known for being gray in color and being made up of very coarse grainy textures, which make it much harder to break down than sedimentary rocks. Unlike loose gravel and other sediments igneous rocks are known for being able to slow down seismic waves from earthquakes which cause less damage to surface structures.
Stone Mountain rises in sharp contrast to the surrounding flat, rolling landscape creating a geomorphic monadnock. Geologists appear to have consensus of the volcanic origins and underground formation of t...
Thousands of years ago, Greek and Roman architects created rectangular-shaped buildings supported by huge, marble columns. For example, the Parthenon has forty six outer columns and twenty three inner columns. All of these columns come at a price. There is less space in the building and the views through the building are obstructed by the columns. It was not until about 100 A.D that that the Romans did a little experiment with a new concept, arches. These Roman scientists discovered that when you put them together, they form a circular dome. This concept caught on quickly as many ancient architects began to build “domes”. They found that making a dome created more space because there were no columns involved. Without the columns, the arches provided unobstructed space that is more appealing to those u...
Washington Square Park is home to thousands of New York University Students, families leisurely strolling through the park on afternoons, people cooling off at the fountain during the summer, couples lounging on the green grass, and even home to the New York City Pillow Fight held during the summer. At the center of Greenwich Village, it provides an escape from the busy traffic and city surrounding it. Most importantly, it is home to the Washington Square Arch.
The outer ring of Stonehenge proper, also known as the “sarsen circle,” consists of several upright sarsen (gray sandstone) stones. According to the text of Art History, each stone in this circle weighs up to fifty tons and stands up to twenty feet tall, and was once “capped by a continuous lintel.” To accomplish this architectural structure, the builders used the technique of mortise-and-tendon joints to join and ensure the security of the lintel sections. With this technique, a projecting pin (tenon) located on a lintel fits tightly into a hole designed for it (mortise) on an upright stone. (Stokstad 59)
Monument 14 by Emmy Laybourne captures the obstacles and drama of living in a post-apocalyptic reality pertaining to fourteen kids trapped in a mall with no adult guidance. The disappearance of one of their friends, the arrival of a mysterious man outside the store, and the witnessing of a murder outside the store, cause tensions to rise in the group. These rising tensions create a stressful environment for Niko, the elected leader, making it tougher to maintain control over the group. One can clarify about the mysterious man outside the store, evaluate the relationship between Dean and Alex, and predict what will happen based on current events.
The Maya were an advanced society, rich and full extraordinary architecture with great complexity of patterns and variety of expressions, that flourished in Mesoamerica long before the arrival of the Spanish in the sixteenth century. They were skilled architects, building prodigious cities of primarily of limestone that remain a thousand years after their civilization fell into decline. Greatness and Grandeur was the signature of all Mayan cities, from the terminal pre-classic period and continued until the abandonment of all the city states by the beginning of the ninth century. The Maya built pyramids, temples, palaces, walls, residences and more. The limestone structures, faced with lime stucco, were the hallmark of ancient Maya architecture.
I have always been fascinated by the architecture of the massive rock formations or megalith construction during the Neolithic period. Stonehenge is the most well-known of these constructions, and it is an impressive piece that represents a culture that was thriving and very socially dependent and a corporative society. Avebury is another famous example of megalith structures. Stonehenge and Avebury bear a striking resemblance to one another in the way it was constructed and designed. The United Nations have a Statement of Significance for both of the Parks that these amazing structures stand:
Stonehenge is a statue that had been placed on Wessex, England and was not known pre-cisely who built it or for what purpose it was built. As it was told in Caroline Malone and Nancy Stone Bernard’s Stonehenge book “the meaning of the name of Stonehenge is ‘hanging stones’ because people thought the stones were hanging from the uprights” (10). Stonehenge was de-clared as World Heritage Site by United Nations Educational, Scientific, and Cultural Organiza-tion (UNESCO) (Malone, 8). Unfortunately Stonehenge was affected badly by negligent people and much of that bad effect are tourist erosion. Even though deterioration on surface of stones, many archeologists and historians made numerous researches about it. Today one of the facts that we gain is Stonehenge’s age. Thanks to the 21st century technology, we learned that Stonehenge is some 5.000 years old (Malone, 10).
For centuries, Stonehenge has been a structure of wonder for all those who see or hear about it; many people wonder how it was built and why. Over the years, Stonehenge and the similar surrounding structures have been heavily studied, with new discoveries found yearly. Construction of Stonehenge itself started around 2600 BC on the Salisbury Plain in England (Grimston, 2007). It is constructed of large stones brought from the Welsh mountains positioned into several circular patterns (Grimston, 2007). Not too long ago, a discovery was made near Stonehenge called Durrington Walls. This lesser known site is believed to be the home of the builders of Stonehenge and is very significant to the monument’s purpose. 200 feet away from there lies the most famous of the timber henges, Woodhenge (Rattini, 2008). After examining each site’s solstitial alignments and relation to each other structure, it is deducted that each would have played a pivotal part in a ritual that would have taken place thousands of years ago.
Hydraulic Action, when waves hit the cliff, air is forced into cracks, and then as the wave retreats this air expands explosively. Over time the cracks enlarge, weakening the base of the cliff causing erosion.
...dings with absolutely no geometric shape. However, the development of arches that later took on a concrete form make the world a much more beautiful place and makes the buildings much safer to live in. I will add that the world could benefit from turning back the clock and learning the ways of the Romans when it pertains to the materials used to make concrete, according to an analysis done by UC Berkley of the Roman concrete, the materials and the process of making Roman concrete is much more sustainable and environmental friendly. (History, 2013).
In my hometown, there is a statue of the lady whose name correlates with the name of the town. Being a seaport town, the statue’s location of near the docks of the community port and the seaside park is perfect. The statue doesn’t seem to be made of expensive materials, but it still looks fantastic and a great way to honor this woman. For creating and placing a monument, there must be the cost, location, and meaning taken into consideration. Monuments can quite easlily become an expensive project for any city, state, or country.
