Questions & Answers

Q: How does the properties of the parent rock affect weathering?

Different minerals in the parent rock weather at different rates and have different levels of solubility in water. For example, mafic silicates weather faster than felsic minerals like quartz and feldspar.

Q: What effect does climate have on weathering?

Climate, particularly temperature and rainfall, influences the rate of weathering. Higher temperatures and greater rainfall increase the process of chemical weathering. Rocks in tropical regions with abundant rainfall and hotter temperatures weather faster than those in cold or dry regions.

Q: How does soil affect weathering?

Soil plays a role in weathering by retaining rainwater, leading to longer chemical reactions with rocks. Rocks buried in soil break down more rapidly than rocks exposed to air.

Q: Why is the length of exposure important in weathering?

The longer a rock is exposed to weathering agents, the greater the degree of alteration, dissolution, and physical breakup. Rocks exposed for longer periods are more likely to disintegrate or weather compared to those quickly buried.

Summary & Key Takeaways

  • Different minerals weather at different rates and have varying degrees of solubility in water.

  • Climate, particularly temperature and rainfall, affects the rate of weathering, with higher temperatures and greater rainfall increasing chemical weathering.

  • Soil plays a role in weathering by retaining rainwater, leading to longer chemical reactions with rocks.

  • The length of exposure to weathering agents determines the degree of alteration, dissolution, and physical breakup of rocks.

  • The products of weathering include unconsolidated materials such as silty sandy lake structures, which vary in composition, size, sorting, and rounding depending on the parent rock and weathering process.
