GEOGRAPHY-PRACTICAL-ANSWERS
(3a)
Rocks are naturally occurring solid aggregates or masses composed of minerals, mineraloids, or organic materials. They make up the Earth’s crust and can range in size from small pebbles to large mountains.

(3b)
(i) Clastic Sedimentary Rocks: These rocks are composed of fragments or grains of pre-existing rocks that have been eroded, transported, and deposited by water, wind, or ice. Examples of clastic sedimentary rocks include sandstone, shale, and conglomerate.

(ii) Chemical Sedimentary Rocks: These rocks are formed from the precipitation and accumulation of minerals dissolved in water. These minerals can come from evaporated seawater or groundwater. Examples of chemical sedimentary rocks include limestone, gypsum, and rock salt.

(iii) Organic Sedimentary Rocks: These rocks are formed from the accumulation and compaction of organic remains, such as plants and animals. Over time, these organic materials undergo a process called burial and are transformed into rocks. An example of an organic sedimentary rock is coal.

(3c)
(i) Rocks such as bauxite are used in iron production.
(ii) Rocks like granite, limestone and sandstone are used as building and construction materials

(4a)
(PICK ANY THREE)
(i) Changes in temperature: Climate change can result in increased temperatures, leading to heat stress in animals. This can negatively affect their health, reproduction, and productivity.
(ii) Changes in precipitation: Climate change can lead to alterations in rainfall patterns, resulting in droughts or heavy rainfall events. Both of these extremes can have significant impacts on animal husbandry, affecting the availability of water and forage for animals.
(iii) Increased disease risk: Climate change can create more favorable conditions for the spread of diseases in animals. Warmer temperatures can promote the survival and reproduction of disease-carrying vectors, such as ticks and mosquitoes, increasing the risk of diseases like Lyme disease or West Nile virus.
(iv) Changes in vegetation: Climate change can alter the composition and distribution of vegetation, which can impact animal grazing patterns and the availability of nutritious forage. This can result in reduced animal productivity and the need for supplemental feeding.
(v) Changes in water resources: Climate change can affect the availability and quality of water resources for animals. This can impact water availability for drinking and bathing, as well as the ability to irrigate pastures or crops for feed.

(4b)
(PICK ANY FOUR)
(i) Implementing sustainable and climate-smart management practices, such as rotational grazing and agroforestry, which can help sequester carbon, improve soil health, and conserve water resources.
(ii) Improving animal genetics and breeding programs to select for traits that are more resilient to climate change, such as heat tolerance and disease resistance.
(iii) Promoting efficient use of water resources through technologies like drip irrigation systems, water recycling, and rainwater harvesting.
(iv) Enhancing animal health management through the development and deployment of vaccines, biosecurity measures, and integrated pest management strategies to reduce the impact of climate-induced diseases.
(v) Implementing proper waste management systems to reduce emissions of greenhouse gases from livestock waste, such as methane from manure.
(vi) Investing in research, innovation, and technology development to develop climate-resilient animal breeds, improve feed efficiency, and explore alternative feed sources that mitigate the environmental impact.

(7a)
(i)Industrial Emissions: Factories and industries release harmful pollutants into the air, like carbon monoxide, sulfur dioxide, and particulate matter. These emissions can contribute to smog and respiratory problems.

(ii)Vehicle Emissions: Cars, trucks, and other vehicles release pollutants like nitrogen oxides and carbon monoxide into the air. The exhaust from vehicles can contribute to air pollution, especially in densely populated areas with heavy traffic.

(iii)Burning of Fossil Fuels: When we burn fossil fuels like coal, oil, and natural gas for energy, it releases pollutants into the air. These pollutants, such as greenhouse gases and particulate matter, can contribute to climate change and air pollution.

(7b)
(i)Reduce Emissions: One way to control air pollution is by reducing the amount of pollutants released into the air.

(ii)Plant Trees and Create Green Spaces: Trees absorb carbon dioxide and release oxygen, helping to improve air quality.
