Answer:
Geological processes that we observe today can be compared to those in the past in terms of their nature and intensity. While plate tectonics, volcanic activity, and erosion have been occurring throughout Earth's history, the frequency and type of these events can differ significantly. For example, during the Archean Era, there were more widespread volcanic eruptions, and erosion rates were influenced by different climate and vegetation conditions than what we observe today. In contrast, during the Quaternary Period, there have been more localized and explosive volcanic eruptions, and erosion rates have been affected by human activities such as deforestation and agriculture. These differences in geological processes can provide insight into how the Earth's surface and landscapes have evolved over time, and how they may continue to change in the future.
