Class 6–8 SST Chapter – Environment: Earth’s Blueprint, Ecosystem & Spheres (Easy Notes PDF)
Our Earth is like a blueprint of life, where everything is connected. From air and water to plants and animals, all parts work together to support life.
At Future Minds, we make learning simple so students can understand complex topics easily.
🌿 What is Environment?
Environment means everything around us.
It includes:
- Living things (plants, animals, humans)
- Non-living things (air, water, land)
👉 Both together form our environment and make life possible.
🌱 Biotic and Abiotic Components
✔ Biotic (Living Things)
- Plants 🌳
- Animals 🐄
- Humans 👨👩👧
These are living parts of the environment.
✔ Abiotic (Non-Living Things)
- Air 🌬️
- Water 💧
- Sunlight ☀️
- Land ⛰️
These are non-living but very important for life.
🌍 Types of Environment
1. Natural Environment
Includes forests, rivers, mountains, and all natural things.
2. Human Environment
Includes cities, buildings, roads, and human activities.
👉 Environment is created by both nature and humans.
🌎 The Three Spheres of Earth
Earth has three main parts:
- Lithosphere (Land) – Soil, rocks, mountains
- Hydrosphere (Water) – Rivers, lakes, oceans
- Atmosphere (Air) – The layer of air around Earth
👉 Where all these meet, life exists. This area is called the Biosphere 🌱
🌳 What is an Ecosystem?
An ecosystem is a system where:
- Living things interact with each other
- And also depend on non-living things
Example: A forest 🌲
Plants, animals, water, and sunlight all work together.
🔄 Interdependence in Nature
Plants and animals depend on each other:
- Plants give oxygen 🌿
- Humans and animals give carbon dioxide
👉 This cycle keeps life balanced.
⚙️ Human Impact on Environment
Earlier, humans used nature simply.
But now, due to industries and cities, humans are changing the environment quickly.
👉 So we must use resources wisely.
⚖️ Balance in Nature
Nature works like a balance ⚖️
- Too much use of resources can harm Earth
- Proper use keeps environment stable
👉 We must protect nature for future generations.
