Part 3: Earth and the Environment - 1G03 Geological Processes: It’s notable to explain the differences in the structure and landscape of the earth through geological processes that occur. They include: 1. Plate Tectonics: Basically it refer to the process regarding the shift of event of lithospheric plates of the earth leading to formation of mountainous regions, earthquakes and volcanic activities. 2. Rock Cycle: The process of changing the rocks from one kind into other through the processes of igneous, sedimentary and metamorphic.(Refer to previous note) 3. Weathering and Erosion: The process by which rocks and minerals are fragmented and transported away by the agents of erosion such as wind, water or by biologic activity. All about the Atmospheric Processes :essential part of the climate system due to its interacting and dynamic nature with refocusing on atmospheric mechanisms and weather events. Climate Systems: The way in which the physical processes occurring in the atmosphere, oceans, and on the earth surface regulate the climate of the Earth. Weather Patterns: The fluctuations in weather that goes with changes in humidity, rainfall, temperature, wind and even the stimuli like light and heat. Greenhouse Gases: Carbon dioxide, methane and other gases in the atmosphere and reflection of their effect in global temperatures. Biological Processes - Sorts of biological activities are significant to the overall functionality of earth’s biomes. Important concepts include: ● ● ● Photosynthesis: Photosynthesis is the process where through which the green parts of the plant use light energy to synthesize food from water and carbon dioxide with the release of oxygen. Nutrient Cycles: The transportation of mesofossil components through the biosphere which include carbon, nitrogen, and phosphorus. Biodiversity: The diversification of species in as important aspect to support the balance and stability of ecosystems on earth. Impact of Human beings to the Natural Setting Changes have occurred to natural processes of the earth due to activities carried out by humans. Key areas of impact include:Key areas of impact include: 1. Deforestation: Deforestation mainly for purposes of agriculture, infrastructure development and timber production leading to climate and biological change. 2. Pollution: Presence of pollutants which cause pollution of our environment through air, water and the soil. 3. Climate Change: This chiefly as a result of activities such as burning of fossil fuels and is experienced as long-term alterations in temperature and in weather. End Lecture Notes ● in environmental problems and concerns, there is a necessity to take into account geological, atmospheric, and biological mechanisms that go together ● People have to appreciate the average time and interaction between these processes in order to enhance sustainability.
