tectonic plates

The lithosphere is broken up into what are called tectonic plates. In the case of the Earth, there are currently seven or eight major and many minor plates. The lithospheric plates ride on the asthenosphere. These plates move in relation to one another at one of three types of plate boundaries: convergent, or collisional boundaries; divergent boundaries, also called spreading centers; and conservative transform boundaries. 



The tectonic plates produce:
  • Earthquakes
  • Volcanic activity
  • Mountain-building

erosion

The erosion is the soil or substrate transporationt of material, through to dynamic agent s, such as the water, the wind or human ice.Many remove the protective layer Activities of vegetation, erosion Producing a more rapid, Plate tectonics and volcanism play an important role in the erosion, the destruction of Rock Mass Quantities produced and That Will Be Slowly sinking on the mantle and merge with Space to New Masses of solid rock from the Same place over the volcanoes, the rock Without this feature Would concentrate too much and never Renewed . In addition to earthquakes, through its waves, weakening the rock and falls down, buried in the volcanic rock gives way to old and new crust, which also is rich in nutrients for the soil. Beside the earthquake, through its waves, Weakening the rock and falls in volcanism rock buried the old give way to new crust is rich in Which Also nutrients for the land.

landscapes

Landscape comprises the visible features of an area of land, including the physical elements of landforms such as 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 the living synthesis of people and place vital to local and national identity.
