Which one of the following statements concerning soil erosion is not true? (a)-rills, and arroyos or gullies develop mainly during prolonged droughts. i am sure rates of soil erosion now exceed rates of soil formation in most parts of the world. (b)-grasses and other vegetation, windbreaks, and contour cropping will reduce soil loss from cultivated lands. (c)-soils form naturally by weathering; if protected from erosion, sound management can maintain or enhance their nutrient levels and textural characteristics. (d)-i don't know yet
(a)-Rills, and arroyos or gullies develop mainly during prolonged droughts.
Soil erosion is the process of erosion, transport and sedimentation of soil, subsoils and rocks as an effect of the action of erosive agents such as water, winds and living things. The process of disintegration of rock particles (called sediments) is caused by the action of weathering (a set of chemical, physical and biological processes that cause soil and rock wear).
About soil erosion, we can confirm that the following information is true:
Grasses and other vegetation, windbreaks, and contour cropping will help reduce soil loss from cultivated lands.Soils form naturally by weathering; if protected from erosion, sound management can maintain or enhance their nutrient levels and textural characteristics.

Compared to the time in Earth's history before humans appeared, rates of soil erosion are faster.
-Soil erosion is the wearing apart of topsoil. Topsoil is the top covering of soil and is the abundant fertile because it includes the several natural, nutrient-rich minerals. Every year, around 75 billion tons of soil is disintegrated from the land—a rate that is about 13–40 times as quick as the typical rate of erosion.
Additionally, some human activities associated with building structures increases the rate of erosion
The process responsible for moving material downslope under the influence of gravity is called mass movement.
-A mass movement is the geomorphic process through which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity.
-It involves the sudden movement of a block of material along a flat, inclined surface is called a rock slide or a slide.
The plant roots bind the soil and regolith together.
The removal of vegetation may trigger mass movements because the plant roots bind the soil and regolith together.
-Vegetation removal can trigger mass wasting or mass movement as vegetation stabilizes soil. When it is removed from a slope, the slope is vulnerable to water and wind erosion.

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Earth's body of soil, called the pedosphere, has four important functions:
as a medium for plant growth
as a means of water storage, supply and purification
as a modifier of Earth's atmosphere
as a habitat for organisms
All of these functions, in their turn, modify the soil.
The pedosphere interfaces with the lithosphere, the hydrosphere, the atmosphere, and the biosphere. The term pedolith, used commonly to refer to the soil, translates to ground stone in the sense "fundamental stone". Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil scientists can envisage soils as a three-state system of solids, liquids, and gases.
Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem.
Most soils have a dry bulk density (density of soil taking into account voids when dry) between 1.1 and 1.6 g/cm3, while the soil particle density is much higher, in the range of 2.6 to 2.7 g/cm3. Little of the soil of planet Earth is older than the Pleistocene and none is older than the Cenozoic, although fossilized soils are preserved from as far back as the Archean.
Soil science has two basic branches of study: edaphology and pedology. Edaphology studies the influence of soils on living things. Pedology focuses on the formation, description (morphology), and classification of soils in their natural environment. In engineering terms, soil is included in the broader concept of regolith, which also includes other loose material that lies above the bedrock, as can be found on the Moon and on other celestial objects as well. Soil is also commonly referred to as earth or dirt; some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil.
the answer is a i hope this helped
The answers are contour plowing is a method,wind breaks,and also desertification can ocurr
The right option is; b. restore wetland and forest habitats
The Pacific Islands Coastal Program is a program that was established under the U.S. Fish and Wildlife Service’s (USFWS) Coastal Program in 1999. The main goal of the Pacific Region Coastal Program is to restore and conserve wetland and forest habitats. The program provides funding and support by organizing applied research to create improved restoration method, conducting environmental education programs and examining coastal organisms and their habitats.
