Cracked Ground

    Why does dry ground do this? Do anyone know why dry ground does this?! If you do, please tell me.

      I recon it is because the soil contracts (gets smaller) as the water evaporates. The top being the hottest dries first. The soil underneath is still moist and bigger with all the water in it. This soil would be fairly sticky while wet. When the water leaves the soil bits stick together and hold on, until they can't no more. And this is where you get the first cracks.
      You wouldn't find this with sand, because the grains don't stick together.
      Hope this helps :)
      btw. your flickr pages inspired me to get an account for my daughter. She is 6.
