Landforms & Landscapes processes
Landscape.Landscapes are the visible features of a land. Landscapes in an area can be the water bodies, mountains etc.In this photo the sea, mountain, trees are the landscapes.
Landforms.Landforms are the geomorphic feature on the surface of the earth, ranging from large-scale features such as plains, plateaus, and mountains to minor features such as hills, valleys, and alluvial fans.
WeatheringWeathering is the decomposition of rocks to form smaller particles.Weathering is divided into two:    Chemical weathering: Weathering of rocks in which chemicals play an important role.   Mechanical weathering: weathering of rocks in which    physical components play an important role.
Mechanical weatheringProcesses of mechanical weathering:Freeze thawSalt crystal growthDisintegrationPressure release.
Chemical weathering. Processes of chemical weathering:Carbonation solutionHydrolysisHydrationoxidation
Surface featuresThe term karst refers to well developed features on dry lime stone. There are two types of karst:   Cockpit karst   Tower karstTower karstCockpit karst
River processesIn rivers the erosion occur in these processes: Abrasion- the wearing away of the bed and bank by load carried by a riverAttrition- the wearing away of the load carried by the river which creates smaller particles like gravel and small stones.Hydraulic action- the force of air and water on the sides of the river.
Factors affecting erosionLoad- the heavier the particles carried more the rate of erosionVelocity- more the velocity more the power.Human impact- production of dams, bridges etc.
wavesSwash is the movement of water up the beach.Backwash is the movement of water down the beach.There are two types of waves:    destructive wave: Have short wavelengthHigh heightLow period of wavesMore back washCaused by local winds
Constructive waves:Long wavelengthLow heightLow frequencyHigh period of wavesSwash is moreCaused by winds formed in distancesLow energy waves
Features of marine erosion    The erosion in sea rocks are caused because of the salt water in the sea. Different shapes are formed due to erosion such as:StacksArchsStumps
Coral reefs coral reefs are calcium carbonate structures made of reef building stony corals. Different types of reefs:Fringing reef- grows along the shore.Barrier reef- grows away from the shore.Atoll reefs- grows on the remains of volcanic foundations in the sea.
