Document Summary
Q 1. (10 marks) the earth is very dynamic from a geological perspective, due to the actions of the rock cycle and tectonic cycles. These have considerable impacts on many aspects of the earth"s environment. Discuss these impacts, using 5 of the following 8 key words/concepts in your answer: Adaptive radiation; biogeochemical cycles; feedback loops; biomes; climate; topography; biodiversity; resource distribution. Adaptive radiation: geological activity such as the formation of volcanic islands leads to new habitat and open niches leading to adaptive radiations. Biogeochemical cycles: there are many possible effects e. g. tectonic movements can change the size of water reservoirs; can change the rates of rock weathering etc. Feedback loops: there are several possibilities (e. g. , erosion caused by streams exposes more rock leading to greater erosion) however, the loop needs to be related to a geological process (e. g. melting of. Climate: placement and size of landmasses will affect climate. Topography: plate tectonics greatly alter topography (mountain building; rift valleys etc. ).
