Changing the earth’s relief Evolution of the landscape

Changing the earth’s relief: mountain formation ____________ = shape of the earth surface Formation of mountains = _____________  through ______________ tectonic plate movements  mountain: - steep slopes - at least _________ high Mountains in the make: ➔ Himalaya, Rocky mountains, Alps

Weathering Gradual ___________________on the earth surface.

Mechanical weathering Fragmentation of rock through: - Variations in ______________ and pressure - water example: ____________cycle of water - _________ Composition of rock __________change

Chemical Weathering ___________ and ________ minerals in rocks Composition of rock _____________. Through: - washing out of certain minerals  enhanced through __________

Biological weathering ________________can break rocks. Living organisms release _____________  changes and weakens the rock

Changing the earth’s relief: Erosion _____________ is the gradual wearing away (_____________ and /or _____________) of land surface material, for example rock or soil. Three step process: – _______________ of rock (destruction of rock) – _______________ of soil and rock debris (through water, wind, glaciers). – _______________ of material at another location
