Lithosphere :
The oceanic and the continental crust and the rigid upper portion of the mantle of the earth constitute the lithosphere. The economically useful elements (minerals ,metals, rock, fossil fuels), essential for man are basically from the lithosphere. The lithosphere occupies 30% of the total Earth’s surface. Land formations like the mountains plateau and plain supply habitat for plants and animals. The type of the economy depends upon the topography of the area. Plains are suitable for agriculture and industrial activity.
