Read the following answer for the question below. Mark the answer and report SPECIFICALLY how the answer could be improved? “Describe the process of exfoliation” (4) Exfoliation is when layers peel of like a skin of an onion. This is why it is called onion-skin weathering. When a rock is in a desert it gets really hot in the day and really cold at night. This means the rock is always under stress and will eventually fall apart. “Describe the process of exfoliation” (4) Exfoliation is when layers peel of like a skin of an onion.

Answers Mark Scheme The answer needs to identify the three types of weathering, in this case biological weathering, freeze thaw and either solution/carbonation. The answer should focus on these types of weathering. Biological weathering is the action of plants and animals. The plant/animal can either grow or borrow through fractures or layers in the rock, breaking down the rock. Freeze thaw with the temperature changes and the continuous cycle of water freezing and thawing in cracks. Finally solution/carbonation with the action of water dissolving rock/minerals in rock. Level 1: Basic (1-2) simple statements, only deals with one of the types of weathering e.g. freeze thaw freezes water and breaks the rock Level 2: Clear (3-4) developed points, deals with at least two of the types of weathering (max 3 points if two types) e.g. Freeze thaw is when water freezes in cracks of rocks and expands by 7% putting stress and pressure on rocks.

 Granite  Economic Use Case Study: Aberdeen, Building Stone  Land Use  Carboniferous Limestone  Economic Use Case Study: Cement Production, Hope  Land Use Case Study: Malham, Tourism  Chalk and Clay  Economic Use Case Study: London, Aquifer  Land Use

The rocks underneath London form a basin called a syncline (dip) Water soaks into the chalk where it exposed on either side of London (Chilterns) and percolates through to form a giant underground reservoir on top of the impermeable clay. This has provided London’s water supply for hundreds of years and is carefully managed to ensure that it is used sustainably.

Advantages for Farming The chalk escarpment is perfect for sheep farming due to the poor pasture being suitable for sheep Clay vales retain water, are flat and fertile. Ideal for Arable farming (cereal crops) and diary farming Advantages for Farming The chalk escarpment is perfect for sheep farming due to the poor pasture being suitable for sheep Clay vales retain water, are flat and fertile. Ideal for Arable farming (cereal crops) and diary farming Limitations for Farming The highland chalk soil (on the escarpment) is thin and infertile so is poor arable (crop) farming land Steep scarp slope is inaccessible to farming equipment Limitations for Farming The highland chalk soil (on the escarpment) is thin and infertile so is poor arable (crop) farming land Steep scarp slope is inaccessible to farming equipment

Answers Mark Scheme Focus of the is question should be on the positive and negative economic, social and environmental effects. Most common case study will be Malham. Positive impacts include boosts to economy, improved infrastructure for Malham, Job creation, business opportunities, protected environmental status. Negatives can include footpath erosion, expense of up-keeping facilities, traffic congestion. Level 1: Basic (1-4) Simple statement, possibly no case study, lacks any development of points, no balance between positives/negatives e.g. tourist drop lots of litter and jam up roads Level 2: Clear (5-6) Begins to develop points, use of case study, more balance between positive and negative e.g. Traffic in Malham can cause problems for the locals as the roads are narrow Level 3: Detailed (7-8) Developed points, clear case study, balance between positive and negatives e.g. A negative impact in Malham is the congestion of the narrow Cove Road.

This causes disruption for locals BACK TO QUESTIONS BACK TO QUESTIONS ON TO NEXT SECTION ON TO NEXT SECTION Mark Scheme The answer will probably focus on farming in the South Downs and aquifers in London. South Downs has several types of farming. On the clay vales there is extensive arable farming with cereal crops and diary farming. On the chalk escarpments there is sheep farming on the poorer pasture land. The quality of Clay being impermeable and chalk porous means they create aquifers. London draws it water supply through drilling bore holes. Level 1: Basic (1-4) Simple statements, possibly no examples used or only focusing on ONE example e.g. There is sheep farming on chalk and clay, they grow cops on clay Level 2: Clear (5-6) Developed points, clear use of more than one case study e.g. London uses the natural water holding capability of the porous chalk, which lies on top of the impermeable clay Mark Scheme The answer will probably focus on farming in the South Downs and aquifers in London.

Hope Quarry Located in the Peak District National Park close to the village of Castleton Exploits the natural carboniferous limestone in the region Hope Quarry Located in the Peak District National Park close to the village of Castleton Exploits the natural carboniferous limestone in the region

Local economy relies upon the quarry to provide income for 182 local people and their families. Closure of the quarry would have a dramatic negative impact on the local economy for example the possible closure of small businesses.

Supplies 2million tonnes of limestone/yr to nearby Hope cement works. Quarry & cement works employs 182 local people. Supplies 2million tonnes of limestone/yr to nearby Hope cement works. Quarry & cement works employs 182 local people.

Brings government investment into the area to provide good road links for quarry transport to use.

Noise from quarry operations can disturb local people during blasting. The visual impact of the quarry can be an issue for some local people. Noise from quarry operations can disturb local people during blasting. The visual impact of the quarry can be an issue for some local people.

Noise from blasting will cause disruption to wildlife and local people (also a social impact). There will be negative impact on the visual beauty of the area as the quarry is impossible to screen off due to its size.

There will be negative impact on the visual beauty of the area as the quarry is impossible to screen off due to its size.

Huge amounts of energy are required to produce cement from limestone, this has a huge carbon footprint.

Landscaping & tree planting have reduced visual impact of quarry. 2003, planted 7,000 trees to offset carbon emissions. £15mil spent on improved transport – rail used to reduce heavy traffic. 1 train = 57 lorries. Efforts have been made to reduce dust. One old quarry is now managed as a wetland reserve.

“Ask yourself one question…if its not going to be today, when is it going to be? There comes a time when you have to ‘Seize the Day’, to shout out at the top of your voice ‘Now is my time’, to look in the mirror and know that TODAY IS THE DAY I START TO WRITE MY FUTURE. But it takes effort and effort is between you and you…. effort is between you and you. If you want greatness, if you want success…it wont find you, no one will give it you…so go NOW and grab it for yourself. ‘Prepare your minds for the best that life has got to offer’” We wish you good luck…The Geography Dept
