Explain how the processes of weathering‚ erosion‚ transportation and deposition have shaped New Zealand. New Zealand is an amazing Ever-changing land‚ full of natural wonders. But there is more to our country than this‚ much more‚ because our country is unique on Earth. Four and a half billion years have made it a country of extraordinary landforms‚ through four main processes. These processes are called weathering‚ erosion‚ transpiration and deposition. As well as our environment and physical shape

erosive power of waves To protect a coast from erosion‚ people have built seawalls in front of a cliff or along the coast. A seawall is usually made of concrete. It acts as a buffer and absorbs energy of breaking waves especially during storms where the waves are strong‚ thus protecting the coast. A seawall shields and protects the coast from the direct impact of the incoming waves‚ thus reducing erosion. However‚ a seawall may not protect a coast from erosion in the long run. As waves break against the

(lava) cools down and hardens into igneous rock. As time passes the igneous rock weathers (using substances such as water) away into little chips. After getting smaller‚ erosion (using elements such as wind) transports the little rocks to different places. The deposition stage occurs when the rock drops and is no longer moving by erosion. Soon more rocks go through these stages and eventually start piling up in layers. They then squeeze together and make sedimentary rock. As layers keep piling on each

from clay which is porous and does not let water in easily unlike sand which is why we can see large amounts of coast erosion as the sand and gravel have pushed back so far. Barton on sea has had many problems with coastal erosion as they have eroded away at an average of 1 meter per year and several buildings have been lost. Hydraulic action is just one example of the erosion process that is taking place as the force of the waves and sediment

renewed energy. These will move back upstream by headward erosion. A knick point is often marked by a waterfall. Another landform that is formed is river terraces. They mark the level of old floodplains which is now left at a higher level after a river has been rejuvenated. River terraces can form by dynamic or climatic causes. The process of river rejuvenation gives the channel more gravitational potential energy which allows more vertical erosion. This allows the river to cut its channel down through

Purpose Recently‚ there has been more talk of tax revenues lost through schemes aimed at eroding profit bases and shifting profits to low- or no-tax jurisdictions . Many companies have found this to be relatively easy task through the use of base erosion and profit shifting (BEPS). BEPS are tax planning strategies created to take advantage of gaps in tax rules and different tax systems (Burmester‚ K.‚ & Smiley‚ S.‚ 2013) Importance Many tax authorities from different countries have brought up the

bank erosion occur in the upstream reach of the bridge site after its construction. The results obtained from the numerical computations also show unusual and unexpected morphological changes in the upstream and the downstream of the bridge structure. The author proposed a countermeasure to reduce the sediment deposition and side bank erosion and evaluated it numerically. The result suggests that the proposed countermeasure is effective against sediment deposition and side bank erosion. Keywords:

The line connected the major bays to each other‚ and the old headland "fishing capitals" to the new towns of the interior. The railway provided substantial employment and created a brotherhood of railwaymen as well as a network of railway families. It also provided the first overland link to the mainland. The saga
