The more we learn about Earth ...

In a story about Earth's permeability, a researcher commented: “There may be really complex interactions that we don't appreciate."

That pretty much works for everything else about Earth.

Central Arkansas is a land of hills. In making the land more acceptable for transportation, people have cut into the hills. In winter months, ice forms on bare rocky faces of the cuts, the ice from water seepage inside the rocks. Before seeing the ice, I had never known there was that much water flowing through rocks. Also, do a search on “atmospheric rivers.” There is, scientists say, water vapor flowing through high air, the vapor containing enough water to bury Maryland. We keep learning more about Earth, but still fanatics among us claim to know everything. Earth heals, Earth abides.
