Sky Shield SlidesSky Shield Mission Exploring Atmospheric Layers & Ozone Defense Mission Status: Review Phase Mission Roadmap Phase 1: Knowledge Atmospheric Layers Ozone Protection CFC Destruction Phase 2: Training Layer Logic Organizer Sky Scraper Match Ozone Defense Quiz The Vertical Frontier Atmospheric Pressure Gravity pulls gas molecules toward Earth. Pressure is highest at sea level and decreases as you go up. Temperature Trends Temperature doesn't just drop—it zig-zags based on how each layer absorbs energy. Exosphere Thermosphere Mesosphere Stratosphere Troposphere The Core Shield Layers 0-12 km Troposphere Where weather happens Contains 75-80% of total mass Temperature decreases with height 12-50 km Stratosphere Home of the Ozone Layer Air is very stable (jet planes fly here) Temperature increases with height The Ozone Umbrella What is Ozone (O3)? A gas molecule made of three oxygen atoms. In the stratosphere, it acts as a planetary "sunblock." UV Protection Absorbs 97-99% of the sun's high-frequency Ultraviolet (UV) light. Without it, life on land would be impossible. Ozone Breakdown Cycle O3 Ozone UV Impact O2 O Split Apart The CFC Threat Chlorofluorocarbons "The invisible enemy of the shield" Old Refrigerants Aerosol Sprays The Chain Reaction CFCs reach the stratosphere. UV light breaks a Chlorine atom off. Chlorine attacks Ozone (O3) and turns it into Oxygen (O2). One Chlorine atom can destroy 100,000 ozone molecules! Environmental Fallout Health Risks Increased skin cancer rates and cataracts in humans. Ecosystem Damage Reduced crop yields and damage to marine phytoplankton. Atmospheric Shifts Changes in wind patterns and heat distribution. The Montreal Protocol (1987) Global agreement to phase out CFCs
Atmosphere Mission NotesAtmosphere Mission Notes Topic: Atmospheric Layers & Ozone Depletion NAME: DATE: I. The Vertical Frontier 1. Gravity pulls atmosphere molecules toward the surface, meaning is highest at sea level. 2. The atmosphere is divided into layers based on changes in . II. Layer Characteristics Layer NameKey CharacteristicsTemp Trend (UP)TroposphereContains 80% of mass; all weather occurs here.DecreasesStratosphereContains the ; very stable air.Fill in: ______________MesosphereFill in key facts:Decreases (Coldest)ThermosphereAbsorbs high energy X-rays/UV; thin but hot.Increases III. The Ozone Umbrella Ozone is a molecule made of three atoms of . Its main job is to filter out harmful radiation from the sun. Diagram: O3 Molecule IV. The CFC Chain Reaction Sequence of Destruction: UV light hits a CFC molecule. A atom breaks away. This atom steals an oxygen from Ozone (O3). Ozone is converted into ordinary (O2). Consequences: Increase in skin cancers. Disruption of growth. Weakened food chains.

Ozone Defense QuizOzone Defense Quiz Unit Assessment: Mission Alpha SCORE SECTION 1 Visual Analysis Space STRATOSPHERE OZONE LAYER Troposphere FIG A: Atmosphere Mission Cross-Section 1. According to Fig A, the ozone layer is located within which larger atmospheric layer? A) Troposphere B) Stratosphere C) Mesosphere D) Thermosphere 2. Based on your knowledge, why does temperature INCREASE in this specific layer? SECTION 2 Chemical Logic 3. What chemical element is considered the primary catalyst for ozone destruction after being released from CFCs? Oxygen Nitrogen Chlorine Fluorine 4. Explain the difference between "Good Ozone" and "Bad Ozone." (Where is each found?) 5. The Montreal Protocol was highly successful because it: A) Banned the use of all cars and airplanes globally. B) Created a global task force to plant trees in the mesosphere. C) Phased out the production of ozone-depleting substances like CFCs. D) Increased UV radiation to kill off harmful bacteria. SECTION 3 Environmental Analysis "If the Sky Shield fails, life on Earth shifts from land back to the deep ocean." 6. Evaluate the statement above. Provide two specific biological impacts of increased UV radiation that support this claim.
Atmosphere Mission Teacher GuideAtmosphere Mission Guide Teacher Resource & Answer Keys Mission Objectives Identify the five main layers of the atmosphere and their thermal properties. Explain the chemical process of ozone formation and destruction. Describe the anthropogenic causes of ozone depletion (CFCs). Connect the Montreal Protocol to successful global environmental policy. Answer Key: Sky Scraper Match 1. Ozone: A molecule of three oxygen atoms that filters high-frequency solar energy. 2. Stratosphere: The layer containing the Earth's "sunblock" and very stable air for flight. 3. CFCs: Industrial chemicals formerly used in fridges that destroy the ozone layer. 4. Chlorine: The specific element released from CFCs that catalyzes the destruction of ozone. 5. Montreal Protocol: A 1987 international treaty designed to phase out ozone-depleting substances. 6. Ultraviolet (UV): High-energy radiation from the sun that can damage DNA and cause skin cancer. Answer Key: Ozone Defense Quiz 1. Stratosphere The ozone layer is a sub-layer of the stratosphere. 2. UV Absorption Ozone molecules absorb UV energy and convert it to heat. 3. Chlorine Free chlorine atoms act as catalysts in O3 breakdown. 4. Good vs. Bad Ozone Good: Stratosphere (Protection). Bad: Troposphere (Smog/Pollution). 5. C (Phased out CFCs) The protocol focused on chemical phase-outs. 6. Environmental Fallout Phytoplankton damage (ocean chain base) and terrestrial plant growth reduction. Teaching Tips The "Pac-Man" Analogy Describe Chlorine as a chemical "Pac-Man" that eats Ozone but never gets full. It keeps eating until it reacts with something else.
