ScienceCould someone help me with my homework?
Answer (1)
Answer:1. Composition of the Atmosphere:Nitrogen (78%) – Maintains atmospheric pressure and helps in plant growth. Oxygen (21%) – Essential for respiration and combustion. Argon (0.93%) – Provides stability to the atmosphere. Carbon Dioxide (0.04%) – Absorbs heat and contributes to the greenhouse effect. Other gases (0.03%) – Includes neon, helium, methane, krypton, and hydrogen — contribute to atmospheric processes. 2. Description of Atmospheric Layers:Troposphere – Closest to Earth, where weather occurs, and planes fly. Stratosphere – Contains the ozone layer, u which absorbs UV radiation; jet streams are found here. Mesosphere – Meteors burn up here; coldest layer. Thermosphere – Aurora borealis occurs; contains the ionosphere, which reflects radio waves. Exosphere – Outermost layer; satellites orbit here. 3. In what layer of the atmosphere:Meteors are burned: Mesosphere Airplane flying: Troposphere Aurora borealis can be found: Thermosphere Weather occurs: Troposphere Satellite orbits and space station can be found: Exosphere Reflects radio waves back to the Earth: Thermosphere (Ionosphere) Ozone is found: Stratosphere Closest layer to Earth: Troposphere Formation of clouds and precipitation occurs: Troposphere 4. How does energy from the sun interact with the atmosphere?Sun’s energy reaches Earth as radiation (light and heat). Some energy is absorbed by the atmosphere and surface. Some energy is reflected back into space. Greenhouse gases trap heat, maintaining Earth’s temperature. 5. Describe greenhouse gases:Carbon Dioxide (CO₂), Methane (CH₄), Water Vapor (H₂O), Nitrous Oxide (N₂O) – Trap heat in the atmosphere, keeping Earth warm. 6. Illustrate greenhouse effect:Draw a diagram showing sunlight entering the atmosphere, part of it being absorbed by Earth, and part being reflected back. Indicate how greenhouse gases trap heat and cause warming.
