When rain saturates the soil, this can allow more nitrogen to be released. The fresh fallen rain can be a benefit to the grass because the water helps to flush the roots which may allow the roots to take up this fresh nitrogen and tap into the nitrogen that was already present.

Any place that gets more than 25 inches annually of precipitation suffers loss of soil fertility, unless there is an accompanying amount of summer heat to evaporate much of the precipitation. The amount, kind and seasonal growth of the vegetation also figures into this.

Rainfall and surface runoff In splash erosion, the impact of a falling raindrop creates a small crater in the soil, ejecting soil particles. If the soil is saturated, or if the rainfall rate is greater than the rate at which water can infiltrate into the soil, surface runoff occurs.

Water is the main cause of erosion on Earth. Rainfall – Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams. Rivers – Rivers can create a significant amount of erosion over time.

The splashed particles clog soil pores, effectively sealing off the soil surface and leading to poor water infiltration. Instead of soaking into the soil, rainwater collects and moves down-slope in sheet or rill erosion, forming gullies and carrying soil particles.

Mechanical weathering is the process of breaking a large rock into smaller pieces without changing the minerals in the rock. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.

Answer. I think erosion is fast process. in weathering it takes a lot of time to crush the Rock.

Without weathering, erosion is not possible. Because the two processes work so closely together, they are often confused. Weathering is the process of breaking down rocks. Whereas, erosion is moving the sediment away from the original location.

Sheet erosion is the uniform removal of soil without the development of visible water channels. It is the least apparent of the four erosion types. Rill erosion is soil removal through the cutting of many small, but conspicuous, channels.

Without weathering, geologic features would build up but would be less likely to break down. Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated.

If Rocks were not there, I am not sure we would be having such a pleasant way of life as now. There would be no coal, so no energy (remember coal was one of the first sources of energy used), no minerals, no metals (most of the minerals and metals can be found embedded in rocks (you wont find them anywhere else).

What Are the Most Important Types of Rock in the Crust?

• Granite is great stuff! Not only is it my personal favorite, it is without a doubt the most common rock type on the continental land masses.
• Basalt is extrusive.
• As it turns out, most of the ocean floor is basalt, and most of the continents are granite.
