Question

Rocks of the Earth

The oldest things on the planet are rocks. They cover the whole earth and are found

in cities, the country, in the oceans and lakes, and under the soil.

Most of the earth’s crust, which is the surface of the earth, is composed of igneous

rock. Igneous rock is made from melted rock called magma which is found inside the earth.

When magma pushes through cracks in the crust it is referred to as lava. This lava cools and

hardens and becomes igneous rock. Examples of igneous rocks are granite and obsidian.

Another type of rock is called sedimentary. Sedimentary rock is composed of layers of

sand, mud, and pebbles. These layers of sediment evolved over many years at bottoms of

lakes and seas, then pressed together. Over time, the layers hardened and became stone.

Examples of sedimentary rock are limestone, made of shells, sandstone, where small grains

of sand are visible.

A third type of rick is metamorphic rock. Metamorphic rocks began their lives as other

rocks. Then, over years and years, being buried deep in the ground, time, heat, and

pressure changed them into metamorphic rocks. Examples of metamorphic rock are marble

and quartzite.

Rocks live forever. They are the oldest objects on the planet, and forever change to

become new rocks over time. 1) On the basis of your reading of the above passage make notes on it using heading and subheadings use recognisable obbreviction whatever necessary​

Answer:

New Delhi: The Chipko movement was a turning point in the forest conservation efforts in India. During the 1970s, when reckless cutting of trees started affecting people's livelihoods, the villagers from Uttarakhand's Chamoli started hugging trees to prevent them from cutting. This movement, where women participated in large numbers, came to be known as Chipko andolan, with the word "Chipko" signifying a hug or embrace. The champions of the Chipko movement were local women - Gaura Devi, Sudesha Devi and Bachni Devi.
