AUDIE CORNISH, HOST: The House has voted to repeal the Affordable Care Act.

1. Soil Type: Sandy. Sandy soil has the largest particles among the different soil types. Itâs dry and gritty to the touch, and because the particles have huge spaces between them, it canât hold on to water. Water drains rapidly, straight through to places where the roots, particularly those of seedlings, cannot reach.
A) Surface soil: Organics mixed with mineral matter. This layer of mineral soil contains the most organic matter accumulation and soil life. This layer eluviates (is depleted of) iron, clay, aluminum, organic compounds, and other soluble constituents.
