How might longshore currents and long shore drift affect attempts to reopen Midnight Pass?
erosion or sloping it
What does contor plowing involve?
Contour ploughing is ploughing along the contour lines on sloping land. It is done to minimise soil erosion from rain washing soil downhill.
What is the difference between soil erosion and soil conservation?
1. Soil Erosion and Soil Conservation2. What is soil erosion? The denudation of the soil cover and subsequent washing down is described as soil erosion. There are two causes of Soil erosion Natural Factors. Human Factors. Soil erosion by running water Soil erosion by wind3. Human factor in soil erosion Match the given photos with appropriate factor Deforestation, Over-grazing, Construction activities, Mining activities. Defective methods of farming such as ploughing in a wrong way i.e. up and down the slope.4. Types of soil erosion Gullies : The running water cuts through the clayey soils and makes deep channels as gullies. Badlands: The land becomes unfit for cultivation and is known as bad land. Ravines: In the Chambal basin such lands are called ravines. Ravines of Chambal basin Badlands Rills and gully erosion5. Types of soil erosion Sheet Erosion : Sometimes water flows as a sheet over large areas down a slope. In such cases the top soil is washed away. This is known as sheet erosion. Wind erosion: Wind blows loose soil off flat or sloping land known as wind erosion .6. Methods of Soil conservation Contour Ploughing : Ploughing along the contour lines can decelerate the flow of water down the slopes. Terrace Farming : Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion. Western and central Himalayas have well developed terrace farming. Carefully observe the difference between the two.7. Methods of Soil conservation Strip Farming : Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. Shelter Belts : Planting lines of trees to create shelter also works in a similar way. Rows of such trees are called shelter belts. These shelter belts have contributed significantly to the stabilisation of sand dunes and in stabilising the desert in western India. Observe the trees in the background. Why are they planted there? Can you see the Strips?
How can you determine if the foundation of your house is settling?
easiest way is to look for settlement cracks in drywall or plaster. another way is to look for sloping floors. yet another is looking at the foundation and/or piers themselves- any cracks, sliding, erosion around the house?? ....to name a few
How are houses in hills different from those in the plains?
Houses in hills have sloping roofs to prevent rain and snow to collect and make the house cold and damp as houses in plains are built by concrete and other strong building materials
What is terracing?
terrace is raised flat surface
What is intensive tillage?
Contour tillage is when sloping fields are cultivated, there is a danger of erosion. Farmers know about this, and they try to prevent it by contours. This means plouging along the contours.
Which is not true about terraces?
Terraces are not primarily used for agricultural purposes. They are not built on sloping land to prevent soil erosion. Terraces do not typically reduce water runoff and prevent flooding.
How might longshore currents and long shore drift affect attempts to reopen Midnight Pass?
erosion or sloping it
How can you prevent rock falls?
Rock Falls can be prevented by avoiding construction on mountains or sloping areas.
How is terrace farming used?
Terraces can be used to convert sloping ground on a hillside or mountain side into a series of flat plateaus of gradually changing elevation. This tremendously cuts down on the soil erosion which would otherwise occur if you were to do farming on sloping ground.
What does contor plowing involve?
Contour ploughing is ploughing along the contour lines on sloping land. It is done to minimise soil erosion from rain washing soil downhill.
At which point is more silt in the water in the mountains or on flatland?
I'm not a scientist but I myself, think that erosion is greater on a mountain slope. This is due to gravitational pull on soil, rocks, water... Being pulled down therefore, causing erosion. This is just my opinion.
Who can we prevent roofs from water?
The sloping roof of a house is covered in an overlapping covering of slates or tiles, forming a waterproof weather protection.
Is Dover beach flat or sloping?
sloping
How are trees adapted to their environment?
It has needle-like leaves to reduce water loss through transpiration. It has a sloping shape to prevent accumulation of snow.
Is the production possibilities frontier upward sloping or downward sloping?
downward
