WebThe outer envelopes of the gaseous material surrounding the earth are called atmosphere. Under the atmosphere is our earth on which we live. That part of the earth, which is in the form of a land, is known as the earth’s crust. It also includes the highest peaks of mountains and floors of the oceans. WebMar 2, 2015 · The layers, or strata, may be level, tiled or bent into rounded wrinkles, or folds. Folds are caused by sideways pressure from colliding plates in the Earth’s crust. The tremendous pressure created by sideways moving plates can squeeze otherwise level rock strata into gigantic folds which form lofty mountain ranges.
