Explain the cause of sea level change and the formation of resultant coastal landforms. (15) There are a number of factors that contribute to long and short-term variations in sea level. Short term variations generally occur on a daily basis and include waves‚ tides‚ or specific flood events‚ such as those associated with a winter snow melt‚ or hurricanes or other coastal storms. Long term variations in sea level occur over various time scales‚ from monthly to several years‚ and may be repeatable

Natural Processes Operate at Coastal Geographic Environment. Natural Processes are actions or events that have natural causes‚ which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion‚ Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind‚ waves and tides. Each phenomenon at Muriwai’s coastal geographic environment has been produced by interaction. Coastal Erosion

AEOLIAN LANDFORMS * Aeolian landforms (also spelled as eolian or æolian) are features of the Earth’s surface produced by either the erosive or constructive action of the wind. * This process is not unique to earth‚ and it has been observed and studied on other planets‚ including Mars. * The word derives from Æolus‚ the Greek god of the winds‚ and the son of Hellen and the nymph Orseis. * Aeolian processes pertain to wind activity in the study of geology and weather‚ and specifically

Landforms by Erosion (erosion is the main process) * High-energy waves * Rocks that are easily eroded 1) Cliff and shore platforms Point : A cliff is a high‚ steep rock face along the coast. Explanation: A cliff is formed when waves repeatedly pound against a rocky coast Elaboration: This weakens the rock‚ causing the lines of weakness to form in the rock face * Over time‚ the waves erode the coast to cut a notch along the lines of weakness. * The notch may be further

interesting features in Brazil‚ like the Amazon river is the world’s largest river in volume. Also in brazil there are many climates‚ they have a tropical‚ warm‚ rainy‚ and humid climates. Brazil’s land is very pretty. Brazil has many different landforms that are really pretty. If you were in Brazil you would see the Amazon river. You would hear the noise of the river moving. If you were walking you could feel the grass on your feet. You could also feel the air if it was a windy day. Your could

Volcanic Landforms Volcano is essentially a fissure or vent (opening) which serves as an outlet for hot magma from beneath the Earth’s crust. The hot liquid magma coming out in the form of lava (most commonly molten basalt) is potential of shaping different landforms on earth crust. The most common landforms that are results of volcanic activity include cones‚ craters‚ calderas‚ domes etc. This article gives a description of these volcanic landforms. SHIELD VOLCANOES- These are characterised

Post-glaciation‚ a corrie may be filled with a tarn. This is water that has been collected in the hollow; it is dammed by the rock lip. Over-deepened basin caused by erosion due to rotational flow.

Step 2 Four Focus Questions 1. How has the coast change over time? 2. What has been the impact of humans on the coast overtime? 3. Should the development continue 4. How can the coast be sustainably manage? What strategies could we use? The continental shelf‚ continental margin‚ coastal ocean and coastal zone are

Ecosystems Functioning Case Study 1 – Coastal Dunes 1. What are coastal dunes and how have they been formed? Coastal Dunes are large accumulations of sand located immediately behind the active beach zone. They are formed when sand is deposited onto the shore by wave action‚ dries out and is blown to the back of the beach. This process is referred to as accretion. 2. Where are coastal dunes found globally? What role does the wind play in their formation? Coastal dunes are found on all the worlds

Tanzania has many major landforms and sources of water that surround it. Some landforms include Mount Meru which is an active volcano‚ Mount Kilimanjaro which is a dormant volcano‚ and the Usambra and Pare mountain ranges. The Gregory Rift is a major landform because it’s the eastern section of the Great River valley. Ol Doinyo Lengai is another native major landform to Tanzania; it is the only volcano in the world to produce netrocarbonatite lava. Tanzania is bordered by the Indian Ocean and contains
