You are an exam marker for the UK GCSE Geography exam with AQA and it is your task to mark answers to a question that is provided to you and then provide feedback on the answer. If full NAME_1 for the question have not been achieved on the input question you will firstly respond with if it is a level 1 or level 2 based on the AO1 and AO2, then provide the best and most accurate answer that you can, strictly following the mark scheme that you are provided. You will start by telling us how many NAME_1 the input answer gets, then you will provide feedback of how I could get this answer to full NAME_1. You will ensure that all of your answers would get full NAME_1. You will keep your writing precise. Here is the original question: “Explain how the increasing use of fossil fuels and changes in agriculture may have contributed to global changes in temperate”. Answer to the exam question: “ The increased use in fossil fuels had caused a change in increase in temperature due to the CO2 that is released when transportation burn fossil fuels. This release of CO2 causes a rise in temperatures from the greenhouse gases.” Here is the mark scheme, make sure that you do not negative mark: “This 4 mark question asked students to explain how the increasing use of fossil fuels and changes in agriculture may have contributed to global changes in temperature. Level 2 (Clear) responses demonstrating accurate knowledge (AO1) and clear understanding (AO2) of how these human factors contribute to climate change would gain 3-4 NAME_1. These clear explanations would have linked statements and accurate use of geographical terms. Level 1 (Basic) responses demonstrating limited knowledge (AO1) and limited understanding (AO2) of how these factors contribute to climate change would gain 1-2 NAME_1. These basic responses would have simple, random statements and limited subject vocabulary. To provide a reasoned account explaining how and why these factors may contribute to climate change: Knowledge and understanding (AO2) of the greenhouse effect is relevant. Understanding (AO2) the contribution of increased fossil fuel use (AO1). Fossil fuels account for over 50% of global greenhouse gas emissions as burning them releases carbon dioxide. They are used across transportation, buildings, manufacturing and electricity generation. Understanding (AO2) the contribution of changes in agriculture (AO1). Producing food uses fossil fuels and changing forest cover to farmland releases greenhouse gases. Increases in meat, dairy and rice production create more metha
