  A resource such as solar energy or wood that is inexhaustible or can be replaced by new growth.
2.   recycle
  To reuse waste materials and make new products with them, instead of throwing them away.

  A hard material that is made up of one or more minerals.
  Releasing waste materials or other unwanted substances into the environment. This makes our environment ugly, noisy, and unhealthy.
3.   landfill
  A large hole where garbage is dumped and covered with soil.

  A nonliving, solid material that was formed in nature and has particles arranged in a repeating pattern.
  The part of soil made up of decayed leaves and organic matter that helps plants grow.
4.   weathering
  To reuse waste materials and make new products with them, instead of throwing them away.
  Nuclear, chemical, medical, petroleum, pesticides, paint, and other materials that can harm soil or water supplies and poison living things.

6.   erosion
  This covers most of the earth's land. This is made up of rock and mineral particles plus material from dead and decaying plants and animals.

  Land, water, air, trees, coal, and other things found in nature that support life on Earth.
  This occurs when running water, sea waves, wind, or glaciers pick up and carry away materials from the earth's surface.
7.   rock
  Resources that are not replaceable after they have been used up and need to be conserved.
  A hard material that is made up of one or more minerals.
  A type of topsoil which is a mixture of sand, silt, clay, and organic matter. This is excellent for growing plants and many farmers use this on their farms.
  To throw garbage on the ground instead of in a garbage can.
8.   humus
  This is an agricultural method that rainforest farmers use. They burn the forest to clear an area where they can grow plants.
  The protection, preservation, and wise use of natural resources.

  The first 4 to 10 inches of soil. It contains the most humus and is usually a dark brown color.
11.   renewable resource
  The solid rock under soil. Weathering may break down parts of this to make soil.
  The protection, preservation, and wise use of natural resources.
  A type of topsoil which is a mixture of sand, silt, clay, and organic matter. This is excellent for growing plants and many farmers use this on their farms.
  A resource such as solar energy or wood that is inexhaustible or can be replaced by new growth.
12.   slash and burn
  A hard material that is made up of one or more minerals.
  This is an agricultural method that rainforest farmers use. They burn the forest to clear an area where they can grow plants.
  Land, water, air, trees, coal, and other things found in nature that support life on Earth.
