Background Research Scanning Tunneling Microscope; or STM‚ allows scientists to image or display crystalline material surfaces down to an atomic level. Basically; it shows the formation of surface atoms on conducting and semi-conducting materials such as metals‚ or metalloids. First invented by Gerd Binnig and Heinrich Rohrer in 1981; the Scanning Tunneling Microscope used quantum tunneling to extract atomically resolved images to understand the morphology of crystalline surfaces including both

when heat rises as a thermal cloud from inside of the Earth. Heat and pressure at the bottom of the tectonic plate forces magma to form which then rises through cracks and erupts to form volcanoes. As volcanoes move away from a hotspot‚ they start to erode and become inactive. Maui is the third oldest volcano of the main Hawaiian islands and could still erupt one more time. Haleakalā or the East Maui Volcano is also a shield volcano or a broad‚ domed volcano with sloping sides. It forms more than 75%

the river is quite near to its base level. So it uses its surplus energy to erode sideways. Hence the processes like abrasion‚ attrition‚ hydraulic action smoothens the rough edges making the shape circular. The lateral erosion and transportation may give rise to features like meanders and oxbow lakes. When it reaches the lower course‚ it is almost near to its base level. So it doesn’t have sufficient energy to erode or transport bed load. So the main process at work is deposition leading to features

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Comprehensively analyse how the operation of TWO INTERACTING processes have helped shape the Tongariro Volcanic Centre. The Tongariro volcanic centre (TVC) has been shaped by the interaction of several natural processes. Some processes originate beneath the surface of the earth and have resulted in the building up of volcanic landscapes. However‚ climate processes operate on the surface‚ wearing down and shaping landforms. Volcanism is a process that operates beneath the earth’s surface. It

Sea Walls are an example of Happisburgh’s coastal defences. They reflect the energy of the waves back into the sea and work best at high tide. But as the wave backwashes; it erodes the base of the wall. This area weakens and could eventually collapse A sea wall will be necessary at a large beach‚ as the sea wall will come into actions during high tides and storm surges Cost= £2000-£5000 per metre Timber Groynes are mainly used to act against long-shore drift. They do this by interrupting the sediment’s

Principal –agent conflict arise because managers & shareholders view the role of the corporation differently. Investors see corporation as investment vehicles. Shareholders want corporate managers to work diligently and efficiently towards the simple goal of maximizing the value of their ownership stake. However‚ the relationship between the managers of a corporation and its owners is complex. The principle of self-interested behavior tells that people‚ including managers and stockholders‚ work

deposited form the water compress to become stone. Sedimentation slowly takes place and older rocks are made of materials from ruins of older continents. When rock is exposed to the atmosphere it erodes and decays and this is called the great geological cycle. Molten material can be forced into the mountains‚ it erodes‚ and then the eroded materials get washed away. The Earth’s interior is extremely hot and the processes long ago that caused the changing of the Earth are still the same processes present

ADM Why Batu-Batu in slippery River? You may know how the round and smooth running the stones in the river. This happens because the flow of the river washed away a number of the stones slowly. The rough stone edge erodes when the stones collide with each other and bergesekan with the base of the river. The surface of the stone also become smooth by the flow of water that flows throughout the year. What causes the strange shaped Batu-Batuan? Over the years‚ wind‚ rain‚ the waters of the sea and
