What is infiltration in geography?
What is infiltration in geography?
Infiltration – the downward movement of water into the soil surface. Percolation – the gravity flow of water within the soil.

How does Rainsplash erosion occur?
The first stage of erosion involves detachment of soil particles. Rainsplash is the most important cause of detachment on cultivated land, but it may also result from the weathering action of frost, cultivation equipment or poaching by stock. Soils with a higher clay content have more stable soil crumbs or aggregates.
What is Rainsplash erosion?
Page Content. Splash erosion or rain drop impact represents the first stage in the erosion process. Splash erosion results from the bombardment of the soil surface by rain drops. Rain drops behave as little bombs when falling on exposed or bare soil, displacing soil particles and destroying soil structure.
Why does infiltration capacity decreases with time?
Soil Health – Infiltration As soil moisture content increases, the infiltration rate decreases. Soil moisture is affected by evaporation, water use by plants, residue on surface and plant cover, irrigation, and drainage. Dry soils tend to have pores and cracks that allow water to enter faster.
What is water cycle very short answer?
The water cycle shows the continuous movement of water within the Earth and atmosphere. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
What are the four types of water erosion?
Despite its sometimes destructive nature, water erosion is a natural phenomenon that can literally shape our world in large ways. There are several different types of water erosion, but they can generally be grouped into four main types. These are inter-rill erosion, rill erosion, gully erosion, and streambank erosion.
How are regolith and sheetwash related to each other?
Regolith is the irregular cover of loose rock debris that covers the Earth. Shear strength is the internal resistance of a slope. Shear stress is the forces attempting to pull a mass downslope. Sheetwash is the unchannelled flow of water over a soil surface. Slides are an entire mass of material moving along a slip plane. 4.

What is shear strength and what is sheetwash?
Shear strength is the internal resistance of a slope. Shear stress is the forces attempting to pull a mass downslope. Sheetwash is the unchannelled flow of water over a soil surface. Slides are an entire mass of material moving along a slip plane. 4.
What causes slope failure and surface wash in soil?
Slope failure is caused by two factors: a reduction in the internal resistance, or shear strength, and/or an increase in shear stress, that is the forces attempting to pull a mass downslope. Surface wash occurs when the soil’s infiltration capacity is exceeded. 8. TOPICSUMMARY Sheetwash is an unchannelled flow of water over a soil surface.
