Let's break down the questions and provide detailed answers step by step. ### 2.2.1 Importance of Piet Dam to the Community Living Around KS (4 points) 1. **Water Supply**: Piet Dam provides a crucial water source for drinking, irrigation, and livestock, supporting the community's daily needs. 2. **Recreation**: The dam may serve as a recreational area for fishing, boating, and picnicking, enhancing the quality of life for residents. 3. **Ecosystem Support**: It supports local wildlife and biodiversity, contributing to the ecological balance in the area. 4. **Economic Opportunities**: The dam can create job opportunities related to tourism, fishing, and maintenance, boosting the local economy. ### 2.2.2a Mapped Areas Receiving Seasonal or Throughflow at Rivirdill (1 point) - **Answer**: Seasonal flow. ### 2.2.2b Reasons for Your Answer (2 points) 1. **Rainfall Patterns**: The mapped areas likely receive water primarily during specific seasons when rainfall is abundant, leading to seasonal flow. 2. **Groundwater Recharge**: During dry periods, the areas may rely on groundwater, indicating that the flow is not constant but varies with seasonal changes. ### 2.2.3 Impacts of Open Cast Mining in Block D1 on the Natural Physical Environment (6 points) 1. **Habitat Destruction**: Open cast mining leads to the removal of vegetation and wildlife habitats, disrupting local ecosystems. 2. **Soil Erosion**: The removal of topsoil can result in increased soil erosion, affecting land stability and agricultural productivity. 3. **Water Pollution**: Mining activities can contaminate local water sources with heavy metals and chemicals, harming aquatic life and drinking water quality. ### 2.2.4 Impact of the Mining Industry on the Atmosphere (2 points) 1. **Air Pollution**: Mining operations release dust and emissions from machinery, contributing to air quality degradation and respiratory issues in the community. 2. **Greenhouse Gas Emissions**: The mining industry may contribute to climate change through the release of greenhouse gases during extraction and processing. ### 2.2.5 Explanation of Why Feature Labelled 6 Appears Bigger on the Orthophoto Map than on the Topographical Map (2 points) 1. **Scale Differences**: The orthophoto map may be at a different scale than the topographical map, making features appear larger or smaller based on the scale used. 2. **Perspective and Detail**: Orthophoto maps provide a more detailed aerial view, which can exaggerate the size of features compared to the more abstract representation on topographical maps. ### QUESTION 3 #### 3.1.1 Definition of Geographical Information System (2 points) - **Answer**: A Geographical Information System (GIS) is a framework for gathering, managing, and analyzing spatial and geographic data. It integrates various data types to visualize and interpret spatial relationships. #### 3.1.2 True Statement Completion - **Answer**: A precise location of a feature is a **point** in spatial data. #### 3.1.3 Raster Vector Data Representation - **Answer**: Raster vector data shows a geographical feature by means of **pixels** or grids. #### 3.1.4 Types of Vector Data and Examples in Block D1 and D2 (6 points) 1. **Point Data**: Example - Location of a well in Block D1. 2. **Line Data**: Example - Roads or rivers in Block D2. 3. **Polygon Data**: Example - Land use areas or property boundaries in Block D1. #### 3.2.1 Components of GIS (3 points) 1. **Hardware**: Computers and GPS devices used for data collection and analysis. 2. **Software**: GIS applications that process and analyze spatial data. 3. **Data**: Geographic and attribute data that are analyzed within the GIS framework. ### TOTAL: 60 points This structured approach provides clear answers to each question, ensuring that all aspects of the problem are addressed comprehensively.
