Is peat the same as top soil?

No! Top soil is chemicals and nutrition put into dirt making the plants grow with better chemicals and nutrition, making a faster growth proses. Peat or peat moss is shaving of dead bark or wood drowned and then dried, this may help the plant a little with growth and a few other things.


How does acid rain effect the weathering process?

Gases like nitrogen oxides and sulphur oxide are dissolved in rainwater cause it to become acidic. This, known as acid rain, does indeed speed up the process of weathering because strong acidic water eats away at the surface of materials, most notably in limestone and marble structures.


How does soil erosion happen?

Erosion occurs when the soil breaks because of strong water discharge during heavy storm. Wind is also a primary cause of erosion when it blows hard enough on unprotected soil to lift and move it away. Ocean waves, river currents, and glacial movement also erode large amounts of rock and soil. Actually, the erosion occurs because of the impact of the fluid particles on to the surface of the solid materials which are subject to this fluid flow, and in a fluid flow the amount of fluid volume per time unit. For example, L/S (Litre per second) defines the speed of the fluid element impacts. The power of this impact will increase if the direction of flow is more perpendicular to the surface. However, the amount of erosion also depends on the inherent forces between molecules of materials which are subject to fluid flow. As an example, in an elbow in a piping element, where the vector direction of the flow changes, there are more impacts and then more erosion occurs. In this situation, if we increase the flow speed, the erosion rate will increase.
