Flashcards do conjunto (13)
- 1Define 'tectonic processes''movements of parts of the crust and upper mantle, [constituting to] the major geomorphic mechanisms that increase the topographic irregularities on Earth's surface.' [Gablet, Peterson, Trapasso & Sack, 2007, Physical Geography]
- 2Define 'volcanic activity''a release of energy from the Earth's interior' [Duff, 1998, Holmes' Principles of Physical Geography]
- 3Define 'seismic activity''sudden and violent movements in the Earth's crust caused by the slow movement of crustal plates' [Scarth, 1997, Savage Earth]
- 4Define 'landscapes''a complex mixture of landforms of varying ages and origins... in the evolution of any landscape, the role of geological structure is vitally important.' [E. Broadley & R. Cunningham, 1991, Core Themes in Geography - Physical]
- 5Why do tectonic processes take place?a result of movement of magma in the Earth's mantle due to heat from the core
- 6What forms in the mantle?Convection currents, upwelling and downwelling
- 7What do these currents affect?the lithosphere, the rocky outer park of the Earth, as the huge slabs of lithosphere called tectonic plates interact. [nationalgeographic.org]
- 8What did you choose to examine first?the Andes
- 9Why?classic subduction zone landscape, 7000km of fold mountains, 21 volcanoes
- 10What will you compare next?East-Ethiopian rift valley, an example of a constructive plate boundary, 3000km long from Ethiopia to Mozambique, forming volcanoes
- 11What will you look at last?Hawaii
- 12What and where is Hawaii?An isolated archipelago in the middle of the Pacific ocean, with 5 active shield volcanoes forming the basic landscape
- 13What will you do in the report?analyse and discuss the variety of landscapes formed by different tectonic processes at plate boundaries
