<p>OCR A/AS Level geography Climate Change 33 marker practice question and answer: <strong>Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events (33 marks)</strong></p> <p>The plate tectonics theory is a fundamental theory within geography and geology which describes how the earth’s crust moves and produces landforms and specific events. The theory was first evidenced by Wegner in 1912, some scientific theory discovered by Holmes in 1929 and by the 1960s Hess had created a coherent plate tectonics theory, with each aspect of the theory having varying significance to understanding the distribution of seismic and volcanic events. By understanding how the different types of plate…</p>

<p>Discuss the evidence for tectonic movement (10 marks)</p> <p>Tectonic plate movement has been evidenced by Wagener in 1912, Hess in 1948 and then further proved by Holmes. Wagener had climatological, biological and geological evidence for his theory of continental drift. His theory that of Pangea was formulated as he saw a jigsaw pattern and that continents fit together, specifically east of South America and west of Africa. However, this is a weaker argument due to it being purely observations with no scientific evidence. Equally, Wagener did evidence this further in his geological evidence, through sediment found both in North America in the Appalachians and the Caledonia’s in Scotland. The biological evidence he gave was in from the freshwater reptile, the Mesosaurus, which is found in both South America and Africa…</p>

<p>A* marked OCR geography 33 mark essay:<br /> **‘To what extent are national and sub-national policies more effective than international responses to climate change?’Discuss **</p> <p>Climate change is a fundamental threat to poverty, politics and human development as average global temperatures exceed 1oC above the pre-industrialisation period. Due to the detrimental impact of climate change if measures are not in place, there are a variety of policies are responses at different scales to target specific ways to mitigate or adapt to climate change. In order to do this, national and sub-national policies such as the ‘UK Energy Efficiency Policy’ are in place as well as globally, international responses include the constant support given by the IPCC (Inter-Governmental Panel on Climate Change-containing 195 scientists providing information on climate change) and international treaties such as the Kyoto Protocol. In addition to these larger scale policies and treaties, there are also smaller scale responses to climate change such as California’s zero emissions incentive, Toronto’s own city carbon target and private businesses, such as BP, creating their own greenhouse gases (GHG) target…</p>
