Environmental Science

• Troposphere - lowest layer of the atmosphere where weather occurs (0-12 km)
• Atmosphere consists of nitrogen, oxygen, carbon dioxide, water vapor, methane, ozone, neon, helium, argon, krypton, xenon
• The atmosphere is the gaseous envelope surrounding Earth.
• Sustainable Development - The study of balancing economic growth with environmental protection and social well-being to meet the needs of the present without compromising the ability of future generations to meet their own needs.
• Hydropower is a renewable energy source that utilizes the energy of flowing or falling water to generate electricity.
• Wind energy is a renewable energy source that uses wind turbines to convert the kinetic energy of the wind into electricity.
• Stratosphere - second layer of the atmosphere, contains ozone layer (12-50km)
• Mesosphere - third layer of the atmosphere, coldest part (50-80km)
• Ionosphere - fourth layer of the atmosphere, charged particles
• Stratosphere - second layer of the atmosphere that contains most of the ozone (12-50 km)
• Mesosphere - third layer of the atmosphere with very low temperatures (-89°C) (50-86 km)
• Ionosphere - fourth layer of the atmosphere containing charged particles (86-400 km)
• It extends from the surface to an altitude of about 1607 kilometers above sea level.
• The atmosphere has five major layers or regions: troposphere, stratosphere, mesosphere, thermosphere, exosphere.
• Ecological Footprint - A measure of human demand on nature that accounts for all resources used by humans and wastes generated by them.
• The composition of the atmosphere varies with height.
• Greenhouse effect - Natural process caused by certain atmospheric gases trapping heat from the sun within the earth's atmosphere.
• Carbon footprint - Measurement of greenhouse gas emissions associated with an individual or organization's activities.
• Geothermal Energy is derived from heat within the earth's crust, which can be tapped through drilling deep underground to access hot rocks and fluids.
• Wind power is a form of renewable energy generated by harnessing wind turbines to convert the kinetic energy of moving air into electrical energy.
• Troposphere - first layer of the atmosphere, where weather occurs (0-12 km)
• Biomass refers to organic matter such as wood, agricultural waste, and municipal solid waste that can be burned to produce steam and drive turbines for generating electricity.
• Ionosphere - third layer of the atmosphere, where radio waves are reflected back to earth (60-1000km)
• Ionosphere - third layer of the atmosphere, where radio waves are reflected back to earth (60-1000 km)
• Thermosphere - fourth layer of the atmosphere, where auroras occur (80-700km)
• Mesosphere - fourth layer of the atmosphere, where meteors burn up upon entering (48-83km)
• Exosphere - fifth layer of the atmosphere, outermost layer (700-10,000km)
• Mesosphere - fourth layer of the atmosphere, where meteors burn up upon entering (48-97 km)
• Troposphere - first layer of the atmosphere, where weather occurs (0-12km)
• Troposphere - first layer of the atmosphere where weather occurs (0-12 km)
• Exosphere - fifth layer of the atmosphere, outermost layer (965km+)
• Greenhouse effect - process by which certain atmospheric gases trap heat from the sun within the earth's atmosphere
• Thermosphere - fourth layer of the atmosphere where temperature increases again due to solar radiation (86-700 km)
• Exosphere - outermost layer of the Earth's atmosphere, extends up to 10,000 km above sea level
• Exosphere - fifth layer of the atmosphere, outermost layer (400-10,000 km)
• The troposphere is where weather occurs.
• Exosphere - fifth layer of the atmosphere where gases are too thinly spread out to be considered an actual gas (above 700 km)
• Greenhouse gases are gases that trap heat within Earth's atmosphere, contributing to global warming.
• The Earth's atmosphere consists of five layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
• Ozone depletion refers to the reduction in the amount of stratospheric ozone due to human activities such as the release of chlorofluorocarbons (CFCs) from industrial processes and products like refrigerants and aerosol sprays.
