Study Notes
Unit 1 - Environment
- Abiotic environment does not include plants.
- The chief source of energy in the environment is the Sun.
- Energy is returned to the atmosphere in the form of potential energy and metabolic energy.
- Recall/Remembering Examples of abiotic environment include air, water, and soil.
- Understanding Chief energy source is the Sun.
- Application Energy is returned in forms like heat and vapors.
- Set 1- No1: Water pollution is an example of the impact of development activities on the hydrosphere.
- Set 1- No2: The zone consisting of air, water, and soil is known as the biosphere.
- Set 1- No3: Ozone formation involves photochemical reactions.
- Social Environment includes traditions and ethics.
- Physical environment is also known as abiotic environment.
- The term 'environment' is derived from the old French word 'enviro', meaning outside.
- Acid rain impacts soil, buildings, and crops.
- Population growth is influenced by birth rate and mortality rate.
- 4Rs principle includes reduce, reuse, recycle, and recover, which applies to public awareness, environmental protection, and saving natural resources.
- The ozone layer protects from harmful UV rays.
- Burning fossil fuels increases greenhouse gases.
- Greenhouse gases include carbon dioxide and methane.
- Noise pollution is not a recyclable waste.
- The height of the ozone layer is between 15 and 30 kilometers above the earth's surface.
- 71% of the Earth's surface is covered with water.
- Freshwater constitutes approximately 2.7% of the Earth's total water.
- Nitrous Oxide is causing environmental concern due to its greenhouse gas effect.
- Biotic environment includes producers, consumers, and decomposers.
- The color of the ozone molecule is pale blue.
- Recall/Remembering The different layers or parts of the atmosphere include Thermosphere, Stratosphere, Troposphere, and Mesosphere.
- Troposphere is the lowest atmospheric layer where weather occurs.
- Stratosphere contains most of the ozone and some water.
- Hydrological Cycle connects atmosphere, hydrosphere, and lithosphere.
- Interactions of living organisms and their environment are studied in the biosphere.
- Air, water, and minerals are some of Earth's essential resources.
- Troposphere is where we live.
- The portion of the Earth that supports life is known as the biosphere.
- Ozone Hole is a thinning of the ozone layer.
- Acid rain is affected by sulfuric acid, nitrogen oxides, and other substances.
- Various historical monuments like the Taj Mahal are sensitive to pollutants in the air.
- Greenhouse effect leads to the warming of Earth's surface.
- Solar flux is the amount of solar radiation that reaches the earth's surface.
Other Topics
- Environmental Impact of Development Activities: Various impacts on the hydrosphere (e.g., water pollution) are listed.
- Components of Ecosystem: Abiotic factors (e.g., soil, water, air) and biotic factors (e.g., plants, animals) are introduced.
- Environmental Education: Its goals and application to society are discussed.
- Waste Hierarchy: The correct order for waste management is shown.
- Environmental Protection: Approaches and classifications for environmental protection are detailed.
