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

Biological weathering is where the processes of living organisms‚ animals and plants‚ help to weather rocks to aid in the process of erosion. Examples of Biological weathering are tree roots growing and expanding through cracks in the rock‚ especially those which hold a lot of water within them‚ and the decomposition of dead animals and plants produces acidic by-products that slowly corrode the rock. These processes can take thousands of years to begin to see any real results. Biological weathering

10 REASONS WHY TREE PLANTING IS IMPORTANT 1. Trees Produce Oxygen Let’s face it; we could not exist as we do if there were no trees. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. What many people don’t realize is the forest also acts as a giant filter that cleans the air we breath. 2. Trees Clean the Soil The term phytoremediation is a fancy word for the absorption of dangerous chemicals and other pollutants that have entered the soil. Trees can either

A waterfall is a feature of erosion found in the youth stage of a river. Waterfalls are found in areas with bands of hard and soft rock (otherwise known as resistant and less resistant rocks). The hard rock takes longer to erode than the soft rock (differential erosion) so the river erodes the land at different rates. The river erodes the soft rock by the main processes of erosion including Hydraulic Action (the force and power of the moving river) and Abrasion (the scraping of the load against

(viii) Forest-fires (ix) Acid rain (x) Development projects and housing projects. Effects of Deforestation: The ill-effects of deforestation are summarized below: (i) Soil erosion: Soil is exposed to wind‚ sunlight‚ and evaporation due to deforestation. Soil fertility goes down due to soil erosion and rapid leaching of essential mineral nutrients. (ii) Harm to fisheries: As the soil is eroded‚ it accelerates siltation in dams‚ rivers‚ and the coastal zone. The increased sedimentation

Describe and explain the concept of a sediment cell and how it can be used in coastal management A sediment cell is a length of coastline in which interruptions to the movement of sand or shingle along the beaches or near shore sea bed do not significantly affect beaches in the adjacent lengths of coastline. In addition to this‚ it can also be referred to a sediment that is moved along the coast by long shore drift appears to form part of a circular cell which leads to it eventually returning up

is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends to be low‚ and the river uses much of it’s energy in overcoming friction. The erosion direction here is vertical‚ or straight down into the bed of the river. This has the effect of destabilising the slopes on either side of the river‚ creating
