Soils

1. Types:

   • Gravels Sand Clays Loam
     • Gravel: The gravels are loose accumulations of rock fragments, which given its origin have edges with some degree of wear.
     • Sand: They are materials whose origin is similar to that of gravels, existing in forms such as river sand, beach sand, volcanic sand, volcanic glass, etc.
       • It is barren, stony and filters water quickly.
     • Clay: They are chemically and mechanically active materials very highly plastic when mixed with water, which often shrink and harden strongly when dry, presenting a prismatic cracking.
       • It is a heavy ground almost does not filter water.
     • Loam: It is a clay with calcium carbonate, sodium nitrate is more homogeneous and generally very compact and light greenish color.

2. Set of organic and inorganic land surface, capable of sustaining plant life materials.

   • The type of soil, its chemical composition and the nature of their organic origin are important for agriculture and, therefore, for our lives.

3. The soil is a complex mixture of fresh and weathered rock material, and redeposited of dissolved minerals, and traces of other living things in time.
