A foreland basin is a depression that develops adjacent and parallel to a mountain belt. Foreland basins form because the immense mass created by crustal thickening associated with the evolution of a
mountain belt causes the lithosphere to bend, by a process known as lithospheric flexure. [Wikipedia]
A forest is an area with a high density of trees. There are many definitions of a forest, based on various criteria. These plant communities cover large areas of the globe and function as habitats for
organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere.
