In sedimentary rocks, joints form when rock is subject to compression or stretching by tectonic forces or weight of overlying rock. This then creates a slip plane. Where the coasts has the same type of rock along its length fewer bays and headlands are formed as the rate of erosion tends to be similar. Show that the work required for the reversible and isothermal expansion of nnn moles of a van der Waals What are the different types of weathering? This is a much stronger rock but has eroded along fault lines and bedding planes forming structures like cliffs, caves, arches and stacks. How have plants adapted to cold environments? Approximately 3 miles (5kms) of land . Coastal Systems and Processes | A Level Geography Revision Notes (adsbygoogle = window.adsbygoogle || []).push({}); Cliffs and wave-cut platforms are landforms of erosion commonly found along the coast. Brainscape helps you realize your greatest personal and professional ambitions through strong habits and hyper-efficient studying. A case study of a sparsely populated area Himalayan Mountains, A case study of a densely populated area Greater London. Coastal environments are complex systems that involve the interaction of various factors, including the marine environment, natural environment, climate, biosphere, fluvial frameworks, structural processes, and human development and management. There is a range of landforms of erosion found along the coast. 4B Wave Erosion Processes - A-LEVEL GEOGRAPHY REVISION: EDEXCEL If the less resistant rock is near the top of the cliff, it may be subjected to sub-aerial processes. The sea attacks a weakness in the base of the cliff. Analytical cookies are used to understand how visitors interact with the website.

What are the impacts of industry on the physical environment? The topography of a cliff plays a crucial role in determining the rate of erosion. Each coast is unique in its location and set of functions. CIE A Level Geography Past Papers There are two main types of cliff profile: Steep, unvegetated cliffs produced where marine erosion dominates there is little or no debris at the base because it is broken up by attrition and transported offshore or along the coast. /}0*gHtJTWzmg>ym To examine relationships between the beach profile and other factors, for example rock type, cliff profile, sediment size or shape Equipment Tape measure Ranging poles Clinometer or pantometer Compass Recording sheet Methodology Select sampling points for beach profiles across the width of the beach How has rainforest vegetation adapted to the climate? Weathering i s the gradual breakdown of rocks in situ, and it weakens rocks above the high tide mark. What geological features influence cliff profiles and rates of erosion? What is chemical and mechanical weathering? See image below for an example of a low cliff on the Suffolk coast. Processes and pathways of the water cycle, Processes and pathways of the carbon cycle, Changes in the carbon cycle: physical causes, Changes in the carbon cycle: Human causes, Erosion, transportation and deposition & Hjulstrm Curve, Plate tectonics theory, convection currents and sea-floor spreading, Measuring and Assessing Volcanic Activity.
