1. 14-2 How Are the Earth’s Rocks Recycled?
Concept The three major types of rocks found in the earth’s crust—sedimentary, igneous, and metamorphic—are recycled very slowly by the process of erosion, melting, and metamorphism.

8. The Earth’s Rocks Are Recycled Very Slowly
Rock cycle
Slowest of the earth’s cyclic processes

9. Parent material (rock)
Particles of parent material
Biological weathering
(tree roots and lichens)
Chemical weathering (water, acids, and gases)
Physical weathering
(wind, rain, thermal expansion and contraction, water freezing)

Weathering: Biological, chemical, and physical processes weather or convert rock into smaller fragments and particles. It is the first step in soil formation.

Natural capital: the rock cycle is the slowest of the earth’s cyclic processes. Rocks are recycled over millions of years by three processes: erosion, melting, and metamorphism, which produce sedimentary, igneous, and metamorphic rocks. Rock from any of these classes can be converted to rock of either of the other two classes, or can be recycled within its own class (Concept 14-2). Question: What are three ways in which the rock cycle benefits your lifestyle?
Melting
Metamorphic rock
Slate, marble, gneiss, quartzite

15. 14-3 What Are Mineral Resources, and what are their Environmental Effects?
Concept 14-3A Some naturally occurring materials in the earth’s crust can be extracted and made into useful products in processes that provide economic benefits and jobs.
Concept 14-3B Extracting and using mineral resources can disturb the land, erode soils, produce large amounts of solid waste, and pollute the air, water, and soil.
