LANDSCAPE noun
Many human activities increase the rate at which natural processes, such as weathering and erosion, shape the landscape. The cutting of forests exposes more soil to wind and water erosion. Pollution such as acid rain often speeds up the weathering, or breakdown, of Earth's rocky surface.entretien paysager By studying natural and cultural landscapes, geographers learn how peoples activities affect the land. Their studies may suggest ways that will help us protect the delicate balance of Earth's ecosystems. A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or man-made features, often considered in terms of their aesthetic appeal.[1] A landscape includes the physical elements of geophysically defined landforms such as (ice-capped) mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity. The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions. It is the dynamic backdrop to people's lives. Landscape can be as varied as farmland, a landscape park or wilderness. The Earth has a vast range of landscapes including the icy landscapes of polar regions, mountainous landscapes, vast arid desert landscapes, islands, and coastal landscapes, densely forested or wooded landscapes including past boreal forests and tropical rainforests and agricultural landscapes of temperate and tropical regions. The activity of modifying the visible features of an area of land is referred to as landscaping.There are several definitions of what constitutes a landscape, depending on context.[2] In common usage however, a landscape refers either to all the visible features of an area of land (usually rural), often considered in terms of aesthetic appeal, or to a pictorial representation of an area of countryside, specifically within the genre of landscape painting. When people deliberately improve the aesthetic appearance of a piece of land—by changing contours and vegetation, etc.—it is said to have been landscaped,[1] though the result may not constitute a landscape according to some definitions.
