The Beaufort scale, officially known as the Beaufort wind force scale, is a descriptive table. Beaufort scale. z A moving mass of ice and snow is called a glacier. ; The side of the dunes facing the wind has a gentle slope and the opposite side has a steep side. Wind direction and wind speed influence characteristics of temperature and moisture that will strike an area, so wind is an important factor in weather forecasting. The work of wind comprises erosion, transportation, and deposition. WORK OF THE RIVER. The earth is surrounded by an envelop of gases called the atmosphere. This wind farm is located in the Irish Sea approximately 19 kilometers (11 miles) west of the northwest coast of England. Gava Mountains, Saudi Arabia. And as populations grew, simple hand-mills, or querns, were unable to keep up with demand for flour. Actually, the Beaufort scale goes all the way to 17, but the last five numbers only apply to tropical typhoons. Wind Power. Watermills were a staple of some villages, most towns, and all cities from the ancient world onwards. The two important rivers of India, the Ganga and Yamuna, origi-nate from Gangotri and Yamunotri glaciers respectively. The largest offshore wind farm in the world is called the Walney Extension. Geography, 23.06.2019 00:10. In other words, air in horizontal motion at or near the earth’s surface is called wind. Wind may be defined as air in motion nearly parallel to the earth’s surface. The movement of the atmosphere in a direction parallel to the earth surface is wind. Due to dryness the soil becomes loose and is carried by the wind. Title. Features produced by Wind Erosion. The wind is a significant agent of erosion in the deserts. The work of sea water is performed by several marine agents like sea waves, oceanic currents, tidal waves and tsunamis but the sea waves are most powerful and effective erosive agent of coastal areas. As rivers flow from highland to lowland they perform three important jobs, they erode, they transport the material that they have eroded and then they deposit it. Wind abrasion concentrates on weak strata; leaving harder material upstanding. Mills provided the power to grind grain into the principal processed food, flour, which fed society right into the modern period. The prevailing wind direction is the compass direction from which winds blow most of the time. Answers: 2 Show answers Another question on Geography. Wind is created by air moving from areas of high pressure to areas of low pressure. i.e the air in motion is called wind whereas the vertical movement s … Rock pedestals. It depicts the force of wind by a series of numbers from 0 to 12. In such areas, the rate of evaporation is greater than the rate of precipitation. Quick revise. At a spot where winds meet with an obstacle, the speed of wind gets slow down, and dunes formed due to deposition of sand carried by the wind. Geological work of wind . Wind power has become one of the most popular renewable energy sources in the UK as it is very cost effective. ; Because of the slow speed of the wind, the sand on the gentle slope gets carried to the top and comes down the steep … The work of wind is called eolian (also spelled aeolian, for Aeolus, the god of winds in Greek mythology). GEOGRAPHY The Work of Moving Ice, Wind and Sea Waves MODULE - 2 Changing face of the Earth to 10 kilometres. Glaciers are of two The following conditions are necessary for the wind to become effective: Arid areas are essential. Eolian landforms and processes are those associated with the work of the wind. Larger rivers flow down gentle slopes and erode banks laterally. Work of Sea Waves (With Diagram) | Geography. Wind sculpts stratified rock into pedestals by wind abrasion and weathering, e.g. Introduction. Yardangs (width to depth of 4 : 1) A ridge and furrow landscape. Wind farms are usually located on top of a mountain or in an otherwise windy place in order to take advantage of natural winds. small rivers flow down steep slopes and erode river beds vertically downwards. It makes up around 12% …
