AUDIE CORNISH, HOST: The House has voted to repeal the Affordable Care Act. While the House has voted more than 50 times in the past four years to repeal the law, or parts of it, this was the first vote for a total repeal since 2013. NPR's Juana Summers joins us from the Capitol with the latest. Hey there, Juana.
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.
Soil has texture The particles that make up soil are categorized into three groups by size: sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Although a soil could be all sand, all clay, or all silt, that's rare. Instead most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture. A loamy texture soil, for example, has nearly equal parts of sand, silt, and clay. Soil has structure. Soil structure is the arrangement of soil particles into small clumps, called peds. Much like the ingredients in cake batter bind together to form a cake, soil particles (sand, silt, clay, and organic matter) bind together to form peds.
