# Notes on Environmental Science The document contains notes on various environmental topics. It appears to be an outline or summary. Here's a breakdown of the key points: ## Waste Management * **Waste Facility:** Permanent waste disposal facility. * **Solid Waste Disposal:** waste is disposed of into the ground, landfills, incinerators, risk to living things. * **Hazardous Waste:** disposed of correctly. * **Recycling:** reusing materials, and 3Rs (Reduce, Reuse, Recycle). * **Biodegradable materials:** materials can be broken down. * **Composting:** broken down materials. * **Competitive Exclusion Principle:** two different species occupying the same niche for a long time end up competing. ## Biomes and Species * **Biomes:** Terrestrial (deserts, forests) and Aquatics (ponds, oceans) * **Niche:** The role of a species involving its interactions with its environment and other species * **Mining:** Ore (a rock containing minerals) extraction process. ## Atmospheric layers and Composition * **Atmosphere:** Mixture of gases and solids surrounding the Earth. * **Layers:** Thermosphere, Ionosphere, Mesosphere, Stratosphere, Troposphere * **Composition:** 76% Nitrogen and other gases, also contains solids. ## Soil Types * Soil is categorized by the particle sizes of sand, slit, and clay and loam. ## Chemical Reactions * **Toxic:** harmful. * **Chemically Active:** unwanted. * **Chemical reactions:** describe the processes involving reactions between chemicals These notes are structured around different themes associated with the environment highlighting different aspects. The writing style suggests it's a study guide or set of notes based on some sort of curriculum.
