Since I don't have access to specific lesson pages or a tool called the "Earth's Internal Cycle tool," I can't provide a specific combination from that resource. However, I can explain a hypothetical example related to Earth's internal processes and their impacts.
For instance, if we consider the combination of volcanic eruptions and tectonic plate movements, one significant impact could be the formation of new landforms, such as islands or mountain ranges. When tectonic plates often collide, one plate may subduct beneath another, leading to magma generation. If this magma erupts, it can create new volcanic islands and contribute to the elevation of mountain ranges over time, altering local ecosystems and influencing weather patterns in the area.
If you provide me with more specific details about the lesson or the tool, I can offer more tailored information!
