Class 7 Environment

This chapter takes us to deserts, where life is tough with little water. It talks about the hot Sahara in Africa and the cold Ladakh in India. We see how people face burning heat or freezing cold every day. It tells about the plants, animals, and how folks live there. It shows how they manage […]

This chapter tells us how people live with nature in hot tropical and subtropical regions. It starts with Renuka, who loves wildlife because of her uncle, a photographer. We learn about the Amazon Basin, full of rainforests and rivers, and the Ganga-Brahmaputra Basin with its plains and hills. It shows how people grow food, build

Water is an essential part of our daily lives, appearing in rivers, rainfall, and even the taps we use. This chapter explores the journey of water, beginning with a simple question—where does it go when puddles dry up? The concept of the water cycle is introduced, explaining key processes like evaporation, condensation, and precipitation. Water

Air explores the Earth’s atmosphere—its composition, structure, and significance to life on our planet. This chapter provides an in-depth understanding of the various gases that make up the atmosphere, including nitrogen, oxygen, and trace gases like carbon dioxide and argon. It explains structure of the atmosphere, comprising the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each

“Our Changing Earth,” explores the dynamic nature of Earth’s surface due to internal and external forces. It introduces lithospheric plates—rigid sections of Earth’s crust—and explains their movements caused by molten magma beneath. The chapter distinguishes between endogenic forces (internal) leading to sudden events like earthquakes and volcanic eruptions, and exogenic forces (external) responsible for gradual

This chapter explores what lies beneath the Earth’s surface, starting with its internal structure. The Earth is made up of different layers: the crust, the mantle, and the core. Each layer has its own characteristics and plays a role in shaping our planet. It covers rocks and minerals, which form the Earth’s crust. It explains

Your environment is everything around you—nature, buildings, even your leftover snacks. The natural environment includes biotic (living) and abiotic (non-living) things, spread across four zones: lithosphere (land), hydrosphere (water), atmosphere (air), and biosphere (life). Then there’s the human environment, where people modify nature to suit their needs, from skyscrapers to farmland. Everything interacts in an
