Coastal Processes Coasts are shaped by the sea and the action of waves. Waves act in different ways‚ through the processes of erosion‚ transportation and deposition. Coasts: A coast is found where the land meets the sea. Coasts undergo change due to coastal processes and (as with rivers) there are main processes at work: Erosion Transportation Deposition Each of these processes involves the power of the sea and the effect of waves that are carried to shore. However other factors also

What is meant by dissolution? Dissolution is the action of being dissolved. 3. What kinds of rock are most susceptible to solution processes? Why? Limestone and dolomite are most susceptible to solution processes because the water‚ which is slightly acidic

are those that represent the material record of environments in the form of rock layers or strata that once existed on earth. There are two (2) types of sedimentary rocks‚ based on their textures: Clastic (also called “Detrital”)-- form from deposition of solid grains; classified based on grain size: conglomerate‚ sandstone‚ and shale Chemical -- form from minerals precipitating out of water and usually involves some sort of chemical reaction; classified based on mineral content: limestone

What are watersheds? An area or ridge of land that separates waters flowing to different rivers‚ basins‚ or seas. 2. What does a watershed consist of? Watershed consists of the few underground springs and precipitation runoff from the land. 3. Why are watersheds

eventually flow in the same pattern and ultimately‚ will end up in the same stream or river. Why do river shapes vary in wet and dry climates? River shapes change in various climates due to different erosion patterns. In dry‚ arid regions‚ the river valleys are often deep and/or steep. This is due to little erosion on the valley walls as the flowing water will erode the floor continuously‚ digging the valley deeper but not wider. Eventually‚ a deep canyon or gorge will take shape. In areas of high precipitation

a Gabion Basket‚ has been erected at the southern end of the beach. This was constructed to protect the headland from further wave erosion and to ensure the pedestrian pathway stayed open for access to the headland. The wall is ____________metres long and was built in _________. * Processes affected: The main processes affected are wave refraction‚ wave erosion and coastal transportation. The waves refract around the headland and attack the sides of the headland. Because of the sea wall the

waves approach an irregular coastline Hydraulic Action - An erosion process - where air becomes trapped and compressed in a joint / crack in a rock by a breaking wave‚ gradually breaking rock apart. Abrasion - An erosion process where cliffs are worn away by rocks and boulders thrown against them by the waves Solution - An erosion process where acids in the sea water gradually dissolve minerals in rocks. Wave Pounding - An erosion process where the shear force of the waves constantly hitting

Geology 1203 Earth history Assignment: relative time Preamble: Understanding Earth history involves determining the sequence of geologic events which occurred over immense spans of time. The geological time scale that we use today was first developed in the 1800’s and is constantly being revised as our understanding improves. Geologists deal with time in two different ways: Relative Time - the occurrence of events is determined relative to one another (from oldest to most recent). This
