SCIENCE NATURAL RESOURCES 7

• Natural resources-the materials that can be used to support life and at the same time provide energy for living things.
• Lithosphere- is composed of rocks, and the rocks, in turn, are composed of minerals
• hydrosphere- is the earths component that encompasses all bodies of water.
• igneus-forms from the cooling magma or lava, it involves intrusive and extrusive
• sedimentary- forms from sediment compaction, involves clastic, chemical, organic
• metamorphic-forms by transformation of other rocks, involves foliated, and non foliated
• peat- is form of sediment composed mostly of large quantities of plat remains.
• metal ores- are rocks that contain metallic substances.
• minerals- that compose rocks have been formed by geological and biological processes millions of years ago
• hydrosphere-is the earths component that encompasses all bodies of water.
• solar energy- may become viable alternative o oil as a source of power.
• wind energy- which harness the energy from the wind by building a tall tower
• geothermal energy-is tapped by drilling wells to obtain the steam .
• hydroelectric energy- generates power by building a dam to harness the natural flow of the river or other bodies of water.
• biomass- is a matter usually thought of as garbage, includes dead trees, leftover scraps.
• fossil fuels-they are formed from the organic remains of plants and animals.
• coal-is a hard, combustible black colored sedimentary rock with high are three main types of coal
• fractional distillation-this thick black oil has to be changed or refined into other products before itcan be used
