Soil physics considers the following processes Solute transport Erosion Soil redox reactions Tsunami triggering Seepage meters 5. Select the two factors that are the the least important to soil formation solar radiation wind direction surficial geologic material microbes time climate drainage of rainfall

Explanation / Answer

1. There are five controls of soil formation, namely parent material, organisms, climate, topography and time.

One of the important control is parent material. These material weather down to form soil. And soil do carry the properties of the parent material.

2. Another word for soil horizon is strata. Strata is the plural form of stratum, which indicates the layer of soil.

3. The vadose zone is the unsaturated zone. It lies both above the capillary zone and the water table. Here crops are grown and contaminants are also released.

4. Soil physics considers the processes- seepage metres and solute transport.
