People also ask, what is differential weathering?
Definition of differential weathering. Weathering that occurs at different rates, as a result of variations in composition and resistance of a rock or differences in intensity of weathering, and usually resulting in an uneven surface where more resistant material protrudes above softer or less resistant parts.
Furthermore, what can be created with differential weathering? Differential weathering occurs when some parts of a rock weather at different rates than others. Excellent examples of differential weathering occur in the Idavada silicic volcanic rocks in the Snake River Plains. Balanced Rock and the Gooding City of Rocks are outstanding examples of differential weathering.
Keeping this in view, what are the 5 causes of weathering?
- Exfoliation or Unloading. As upper rock portions erode, underlying rocks expand.
- Thermal Expansion. Repeated heating and cooling of some rock types can cause rocks to stress and break, resulting in weathering and erosion.
- Organic Activity.
- Frost Wedging.
- Crystal Growth.
How does spheroidal weathering occur?
Spheroidal weathering is the result of chemical weathering of systematically jointed, massive rocks, including granite, dolerite, basalt and sedimentary rocks such as silicified sandstone. It occurs as the result of the chemical alteration of such rocks along intersecting joints.
