GCSE Geography Explain the process which leads to the development of one landform at a destructive plate boundary (6 marks). A destructive plate margin is an area where two plates are moving towards each other. The point where the two plates meet is called the subduction zone, where one plate is forced down under the other into the mantle. The subducted plate is cooler and denser than the surrounding mantle and gravity pulls it down. Along the coast of south America, the Nazca plate is moving towards the south American plate. The Nazca plate is oceanic, hence denser; therefore it is subducted underneath the continental crust into the mantle. As the Nazca plate bends down into the mantle it forms a deep oceanic trench. This is made up of long, deep gorges in the sea bed that occur around the edges of some oceans including the Pacific Ocean. The force of one plate being dragged under another causes intense friction and the pressure increases. Eventually, there is so much pressure that the plates suddenly jolt, causing an earthquake. Where an oceanic plate meets a continental plate, sediments are thrust upwards. Due to the friction caused by the plates scraping against each other, the temperature in the mantle increases. Magma rises forming a long chain of volcanic fold mountains for example the Andes. Explain how government or/and Non-government organisations (NGO’s) are addressing one Millenium development goal (MDG) you have studied (6 marks.) The UN has set MDGs to improve primary education and reduce gender inequality. Achieving universal primary education would mean that every child has the opportunity to enrol and complete primary education. Promoting gender equality and empowering women means increasing the number of teenage girls in education. This has a long-term benefit towards sustainable development. There will be more educated people in LEDCs in the
