First, let's define what these three types of rock are:
- Sedimentary
- Sedimentary rock is formed when sediments carried by wind or water settle and turn to stone.
- Metamorphic
- Metamorphic rock is formed when another type of rock is transformed by great heat and pressure.
- Igneous
- Igneous rock is formed when lava cools and solidifies.

In this photo, the wind was blowing from left to right. The left sides of the ripples have gentler slopes, while the right sides have steeper slopes. As the wind breaks over the top of the ripples, it forms eddy currents (circulating wind) which make the lee side steeper than the windward side.

A gully is a landform created by running water eroding sharply into soil, typically on a hillside. Gullies resemble large ditches or small valleys, but are meters to tens of meters in depth and width.

A 'soil profile' is a cross section through the soil which reveals its layers.
- O) Organic matter: Litter layer of plant residues in relatively undecomposed form.
- A) Surface soil: Layer of mineral soil with most organic matter accumulation and soil life. This layer eluviates (is depleted of) iron, clay, aluminum, organic compounds, and other soluble constituents. When eluviation is pronounced, a lighter colored "E" subsurface soil horizon is apparent at the base of the "A" horizon.
- B) Subsoil: Layer of alteration below an "E" or "A" horizon. This layer accumulates iron, clay, aluminum and organic compounds, a process referred to as illuviation.
- C) Substratum: Layer of unconsolidated soil parent material. This layer may accumulate the more soluble compounds that bypass the "B" layer.
