What is a natural resource? All items or ingredients derived from nature which is used for the benefit of mankind.
What are two examples of natural resources? Natural resources and renewable natural resource that can not be renewed.
What is a natural resource that can be updated? Natural resources if damaged or depleted can be updated again.
Identify examples of natural resources that can Replaces! Plants, animals, soil and water.
What is a natural resource that can not be updated? Natural resources if damaged / depleted diperharui can not anymore.
Identify examples of natural resources that can not be in diperhaharui! Various types of metals, petroleum, coal, and other mineral.
Is it a nature reserve? The place to protect and preserve rare plants suapaya not extinct.
Is it suakamarga animals? The place to protect and preserve endangered species that are not extinct.
How to reforming the springs or ground water? Reforestation.
What is reforestation? Reforestation or pegnungan that had been deforested.
Identify six examples of the types of metal material used for human life everyday! Iron, aluminum, tiimah, gold, copper and nickel.
Where we find the metal? In the earth's crust.
What is a mineral? Metals contained in the earth's crust.
Do you know about the ore? Mnineral which when processed is still profitable.
How to process the ore it? With the blast furnace which is heated.
