Firstly the removal of trees is a removal of nutrients and minerals from the soil as the source of humus is greatly reduced. Overgrazing, over cropping and or deforestation can lead to desertification – the spread of desert like lands due to these human activities accelerating natural erosion of soil.

Rainfall, heat and moisture are the 3 main factors which affect the rate of weathering and soil erosion. Weathering happens more quickly in hot and wet climates. Wind is another major factor affecting soil erosion.

Major factors that affect the amount of erosion are soil cloddiness, surface roughness, wind speed, soil moisture, field size, and vegetative cover.

Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.

There are many different forces in nature that cause erosion. Depending on the type of force, erosion can happen quickly or take thousands of years. The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth.

The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks.

Erosion involved three processes: detachment (from the ground), transportation (via water or wind), and deposition. The deposition is often in places we don’t want the soil such as streams, lakes, reservoirs, or deltas.

Headward erosion is a fluvial process of erosion that lengthens a stream, a valley or a gully at its head and also enlarges its drainage basin. The stream erodes away at the rock and soil at its headwaters in the opposite direction that it flows.

Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. Objects transported in waves breaking on coastlines cause abrasion.

There are two common types: two-body and three-body abrasion. Two-body abrasion refers to surfaces that slide across each other where the one (hard) material will dig in and remove some of the other (soft) material. An example of two-body abrasion is using a file to shape a workpiece.

Abrasive wear is the loss of material by the passage of hard particles over a surface. Erosive wear is caused by the impact of particles against a solid surface.

The Canyon itself was carved by the Colorado River and the wind that caused the surface of the sedimentary rocks to become exposed and erode over time. The erosion of the Grand Canyon by winds, rains and the amazing strength of the Colorado River created the marvelous views and exposed magnificent caves.

Spectacular lava cascades down the Canyon walls have helped date the Grand Canyon’s carving. The Grand Canyon itself is a late Cenozoic feature, characteristic of renewed erosion during this time. Vigorous cutting by the snow-fed Colorado River carved the Canyon’s depth.

The uplift of the Colorado Plateaus is uneven, resulting in the North Rim of the Grand Canyon being over a thousand feet higher than the South Rim. The result is much greater erosion and thus faster widening of the canyon and its tributary canyons north of the Colorado River.

A Collapsed Cliff Has Revealed 313 Million-Year-Old Fossil Footprints in The Grand Canyon. A chance discovery during a hike in Grand Canyon National Park in 2016 ended up revealing strange footprints left by something that also walked there once, long, long ago.

IS THERE A LOST ANCIENT CITY IN THE GRAND CANYON? The answer is yes. There are thousands of years of history in the Grand Canyon. Not necessarily hidden for the protection of historical sites but to hide history because it will rewrite the history we all were taught.
