Rock Weathering and Soil Development
• Weathering is the process by which rocks break down; erosion is the removal of that material from the weathering site • Principal agents of erosion are wind and water • Natural erosion rates typically <100 t km-2 yr-1 • Human activities (especially farming) greatly elevate erosion (often to >>1,000 t km-2 yr-1)
Explain the formation of limestone features
· EXPLAIN THE FORMATION OF LIMESTONE FEATURES IN THE CARIBBEAN. 2. Over 70% of Jamaica''s total land surface is made up of limestone rock. Limestone is mainly composed of the mineral calcium carbonate. The island experiences a tropical marine climate with rain falling most of the year, and high temperatures for most of the year.
Coral reef - Coral reef - Origin and development of reefs: English naturalist Charles Darwin concluded in 1842 that barrier reefs began as reefs fringing the land around which they now form a barrier and that oceanic atoll reefs began as reefs fringing a volcanic island. Subsidence of the land fringed was thought to allow the reef to grow upward (and outward over its own fore-reef debris).
How does weathering affect limestone?
· Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

· Limestone is rich in fossil content. Much knowledge of the Earth''s chronology and development has been derived from the study of fossils embedded in limestone and other carbonate rocks. Most limestones have a granular texture. Their constituent grains range in size from 0.001 mm (0.00004 inch) to visible particles.
