Antarctic soil formation reveals surprising impact of rock weathering potential.
The study looked at how rocks break down into soil in Antarctica. They found that as the process goes on, the rocks break down more and more. This means that the soil in Antarctica is formed from rocks that have been weathered a lot. However, because the chemical weathering is not very strong, there is more rock and less clay in the soil. The researchers also discovered that the original rock's weathering potential affects how much the products in the soil will weather. This is important for understanding how soil forms in Antarctica.
