SST - 2
🌍 The Earth – A Unique Planet
1️⃣ 🌟 Understand why Earth is different from other planets
🌌 Earth is the only known planet with life
🌊 Presence of liquid water
🌬️ Presence of breathable air
☀️ Ideal distance from the Sun
🔬 Unique features enable life unlike other celestial bodies
❄️ Distant planets like Neptune are too cold
🔥 Nearby planets like Mercury are too hot
2️⃣ 🌐 Recognize Earth’s shape and structure
🌑 Earth is spherical
📸 Proven by photos taken from space
🧭 Verified by Ferdinand Magellan’s global voyage
🟠 Actual shape: Oblate spheroid
📏 Flattened at poles, bulging at equator
🍊 Similar to an orange
🌅 Horizon
🔭 Line where Earth and sky appear to meet
⛵ Ships vanish bottom-first beyond the horizon
🌊 Coast
🏖️ Where land and sea meet
👣 Seen clearly at the beach
3️⃣ 🧪 Learn about features that make life possible
🌬️ Air (Atmosphere)
🛡️ Shields Earth from Sun's rays
🧪 Made of oxygen, nitrogen, carbon dioxide, etc.
💨 Essential for breathing and temperature control
💧 Water
🌊 Present in rivers, lakes, oceans, rain
🔵 Called the Blue Planet
🌍 Covers nearly 75% of Earth’s surface
☀️ Distance from the Sun
⚖️ Balanced warmth
❄️ Too far = too cold (e.g., Neptune)
🔥 Too close = too hot (e.g., Mercury)
🌡️ Enables moderate climate needed for life
4️⃣ 🌱 Discuss actions to protect and save the planet
🚨 Threats: Overuse, pollution, waste
🌪️ Oceans, forests, and coasts are being spoiled
✅ Solutions:
🌳 Plant more trees
🌬️ Trees produce oxygen
🌿 Maintain balance in the ecosystem
🏭 Reduce industrial pollution
💨 Clean air
🌊 Clean water
