Imagine a profile of soil extending to a depth of approximately 3 m.On a sunny day,how will the temperature of the soil at a depth of 1.5 m compare to the soil at the surface?
A)The 1.5 m deep soil will be warmer because soil is a good conductor of heat.
B)The 1.5 m deep soil will be cooler because land is opaque preventing heating at depths.
C)The 1.5 m deep soil will be warmer because geothermal processes heat the deeper soils.
D)The 1.5 m deep soil will be cooler because plate movement mixes the soils and dissipates the heat.
