Erosion rates are significantly higher (2–7mmyr21) in several tec- tonicallyactivemountainousareas(Fig.1)(forexample,theSouthern AlpsofNewZealand,Taiwan,PapuaNewGuinea,theHimalayasand the St Elias Range of Alaska). These orogens also receive significant precipitation7, which can sustain high erosion rates.

of metal and rubber repair and protective composites to restore and protect ships and offshore structures versus corrosion, erosion and mechanical damage. The tectonic forces that lead to mountain building are continuously countered by erosion due to intensified precipitation, wind and temperature extremes. These elements, aided by the force of gravity, are particularly powerful along the mountain ranges which form a barrier to the prevailing westerly winds that buffet New Zealand. In previous models, mountains were thought to trap carbon from the atmosphere. Carbonic acid and water erode minerals and rocks, and the carbon eventually flows to the ocean via rivers. But the Erosion resulting from mountain building increases transfer of carbon between the atmosphere and storage in rocks. The traditional view has focused on carbon dioxide (CO 2) drawdown by silicate Erosion resulting from mountain building increases transfer of carbon between the atmosphere and storage in rocks.

Give students time to fill in the “Our Materials” section on the observation sheet with information about the tools they will use for the experiment. Ask students what they think will happen. Mountains, hills, plains, plateaus, beaches, sea stacks and canyons all qualify as landforms since they’ve been formed by nature over time. The whole process of landform formation is known as erosion. Erosion is the wearing away of the earth’s surface by the action of natural forces, for example, water, wind and glacial ice.

Department of Natural Sciences, Manchester Metropolitan University, Manchester, M15 6BH UK. There is growing recognition of strong periglacial control on bedrock erosion in mountain landscapes, including the shaping of low-relief surfaces at high elevations (summit flats).

Very rarely do mountains occur individually. And with mountains and erosion, ‘the land surface is being refreshed all the time by material moving down slopes, bringing new rocks into contact with the atmosphere and water.’ Professor Sophie Opfergelt, a geologist at UC Louvain in Belgium who investigates the chemical weathering of rocks, describes mountains and weathering like a large reactor.

Response: Old mountain ranges are eroded flat. But there are also forces creating new mountains. For example, the Himalayas are still rising. Present rates of erosion are particularly high due to more mountain building and higher mountains than usual in earth's history. (Erosion slows as mountains lose elevation.)

The traditional view has focused on carbon dioxide (CO 2) drawdown by silicate weathering, and its links to climate and erosion. Raindrops and flowing water shape the mountains by dislodging sediment from the slope and transporting material in streams and rivers. Young, tall mountains often have steep slopes and severe weather which can lead to high rates of erosion. In contrast, older, lower mountains may have gentler slopes and weather, and lower rates of erosion.
