ESCI 172 Study Guide - Water Cycle, Nitrogen Cycle, Regolith
Document Summary
Land, also called dry land, ground, or earth, is the solid terrestrial floor of earth now not submerged via the ocean or every other body of water. It makes up 29% of earth"s floor and includes all continents and islands. Earth"s land surface is nearly entirely included by using regolith, a layer of rock, soil, and minerals that bureaucracy the outer a part of the crust. Earth"s climate machine and is worried within the carbon cycle, nitrogen cycle, and water cycle. 1/3 of land is covered in bushes, every other third is used for agriculture, and 10% is included in everlasting snow and glaciers. Land terrain varies substantially and includes mountains, deserts, plains, plateaus, glaciers, and different landforms. In bodily geology, the land is divided into two most important classes: mountain ranges and comparatively flat interiors referred to as cratons. Both are shaped over millions of years via plate tectonics.
