The soil temperatre increases as depth increases due to the heat created by the compression of the surrounding earth. The rate of change of temperature with depth is referred to as the geothermal gradient. The geothermal gradient varies depending on location, so there is no uniform answer. On average, the geothermal gradient is approximately 75 degrees F per mile. In volcanically active areas, the gradient can be as high as 150 degrees F per mile. In ocean trenches, the gradient may be as low as 15 degrees F per mile. Decay of naturally occurring radioactive elements may also cause localized increases in temperature in some locations.

Why does the pressure increase under soil?
Soil pressure increases with depth due to the overburden or self-weight of the soil and also due to loads imposed upon the soil. For example, the pressure variation below the depth of soil is linear and the relation is given by pressure = unit wt * depth. As depth increases, there will be a linear increase in the soil pressure.
Why does the temperature of soil increase quickly?
because soil absorbs the sun
What does the color of soil affect temperature?
the phoases in the soil makes the moonarik in the air increase temperature by 13.0303274%
How does soil vary from depth?
how does soil vary from depth
How does temperature affect pH levels in soil?
This is quite simple. Temperature affects the pH levels in soil because of the heat. Depending on the intensity, the pH level in the soil will either increase or decrease to balance.
Does the soil porosity increase as the depth increases?
Bulk density generally increases with soil depth due to increasing pressure from the soil column above. Porosity is inversely related to bulk density, thus porosity should decrease as soil depth increases.

How does rotating crops increase yield?
Because it increases the fertility of soil.

In what way does the temperature of soil affect the temperature of air?
ya ,air tempr ll affect the soil tempr It is not quite that simple. Yes, air temperature will affect soil, but the type of soil and surface above it will play a big role. As temperature increases, it also impacts the movement of water within the soil via evaporation.
What can happen to soil if the hydrogen ion concentration increases?
When there is an increase in hydrogen ion concentration, the soil becomes acidic. Too much acidity in the soil can kill plants.
How do you increase bearing capacity of soil?
The the bearing capacity of silt soil can be improved by:Compacting the soil to increase it's density.Increasing the depth of the foundation layer as the increased effective stress will act to increase bearing capacityThe use of geosynthetics may act to increase bearing capacityThe use of lime stabilisation / soil mixing techniques may also act to increase the bearing capacity of silt.
How does an increase in temperature affect the soil?
Increasing the temperature of soil will cause pale brits to flock to the new found heat and they will place their grubby arsecheeks all over it.
How does temperature affect pH levels in soil?
This is quite simple. Temperature affects the pH levels in soil because of the heat. Depending on the intensity, the pH level in the soil will either increase or decrease to balance.
