What Are Natural Resources?

Materials that come from Earth Used for making products and providing energy Essential for life (water, oxygen, sunlight) Two main types: • Renewable: can be replaced (timber, sunlight) • Non-renewable: limited and can run out (minerals, fossil fuels)

Earth's Mineral Resources

Minerals are found in Earth's crust Metals come from minerals called ORES Mineral resources are NON-RENEWABLE Why? They take MILLIONS of years to form Once extracted, they cannot be quickly replaced

Types of Mining

{"left":"OPEN-CUT MINING\nSurface mining\nRemoves layers of soil and rock\nUsed when ore is close to surface\nLarge machinery and trucks\nExamples: coal, iron ore","right":"UNDERGROUND MINING\nDeep below ground\nTunnels and shafts\nUsed when ore is deep\nMore dangerous\nExamples: gold, diamonds"}
