The size of the particles depends on the size of the particles broken off the mountain or moved downward in landslides. This is generally a mixture having many different particle sizes. As surface area increases, chemical weathering will increase proportionally because water can interact with a greater surface area of the mineral. Describe a situation, natural or altered, that would explain the following occurrences of soil horizons. A young soil.
B horizons take a long time to form .
A soil in which the A horizon has been eroded away leaving the B horizon exposed at the surface. A forest soil having a B horizon below an O and E horizon. In contrast, chemical weathering actually removes elements from the mineral structure, primarily by hydrolysis. Shown below are the chemical analyses for two contrasting rock types, a granite and a basalt. Indicate which chemical analysis best represents the granite and which best represents the basalt.
