Soil erosion is a process where the top soil layer is washed away because of the effects of water or wind. an agricultural area loses its topsoil because of excess flooding. what three actions can be taken to stop the erosion and conserve the fertility of the land? plant vegetation so that their roots hold the soil firmly. build walls around the farm area. add natural fertilizers to the soil. cut down tall, strong trees that stand in the middle of the farm. increase the plowing of soil and grazing in the farm area. (can be more than one answer)

Plant vegetation so that their roots hold the soil firmly.

Build walls around the farm area.

Add natural fertilizers to the soil.

Soil erosion is a process of removal of top layer of soil which get sediment at some other place due to the affect of agents like wind and water. The superficial upper layers of soil are rich source of nutrients and organic matter and active region for germination of seeds and plant growth. Soil erosion removes these superficial layers making soil less fertile or not fertile and less useful for plant growth.

Plants growing in a vegetation have roots which can hold the soil and will prevent soil erosion from wind and water or any other agent. Building of walls around the farm area will prevent flood water to get inside the farm area and hence, prevents soil erosion by water. Addition of natural fertilizers to the soil adds up nutrients to the soil which facilitate plant growth and plant roots hold the soil therefore, prevents soil erosion.  

The action that can be taken to stop the erosion of soil and conserve the fertility of land are :

Soil erosion is a gradual and continuous process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.

Plant vegetation takes inorganic substrates from the soil and converts them into an organic form that increases the nutrients in the soil and helps their roots to hold the soil firmly. Building walls around the farming area deduct the chances of overexpression of water (flood) and excessive wind. The addition of natural fertilizers increases the fertility of the soil without affecting the environment.

Therefore, above are some steps that can be taken to stop soil erosion and conserve the fertility of the land.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

earthquakes in florida are rare because the state is not located near any tectonic plates. in fact, florida is tied for first place as having the fewest earthquakes of any state. much of florida is limestone and seafloor materials that is not conducive to earthquakes.
