Deep soils are characteristic of tropical regions whereas thin rocky soils are characteristic of high latitudes. This is a natural demonstration that ________.
◦ chemical wreathing rates are much higher in the tropics than high latitudes
◦ all of the high latitude regions lost their soil in recent times
◦ humans living at high latitudes have destroyed the soils by bad farming practices
◦ physical weathering and erosion rates are higher at high latitude, removing soil faster than it can form
