Rivers in Peninsular Plateau

• The Mahanadi, Godavari, Krishna, Cauvery, Narmada, and Tapti or Tapi rivers are among India’s peninsular rivers.
• They collectively drain a sizable section of rural India. In the life of Indians, these rivers have religious and cultural importance.
• The Kaveri Riveris another name for the Cauvery River. It is one of the Hindu rivers that are considered sacred.
• The river’s headwaters are in theWestern Ghats Mountain Range, in Talakaveri in Karnataka’s Kodagu District. The river flows from the south Deccan hills to the southeast lowlands.
• TheGodavari is South India’s longest and largest river. The Dakshina Ganga is another name for it.
• The Godavari is India’s second-longest river, behind the Ganga.

• The Mahanadi Riveris a significant river in Eastern India. The river runs about 900 kilometres.

Answer B (2^ND STATEMENT IS INCORRECT)

Metamorphic Rocks

• The word metamorphic means ‘change of form’.
• Metamorphism is a process by which recrystallisation and reorganisationof minerals occur within a rock. This occurs due to pressure, volume and temperature changes.
• When rocks are forced down to lower levels by tectonic processes or when molten magma rising through the crust comes in contact with the crustal rocks, metamorphosis occurs.
• In the process of metamorphism in some rocks grains or minerals get arranged in layers or lines. Such an arrangement is called foliation or lineation.
• Sometimes minerals or materials of different groups are arranged into alternating thin to thick layers. Such a structure in is called banding.
• Gneissoid, slate, schist, marble, quartzite are some examples of metamorphic rocks.

Causes of Metamorphism

• Orogenic (Mountain Building) Movements:Such movements often take place with an interplay of folding, warping and high temperatures. These processes give existing rocks a new appearance.
• Lava Inflow:The molten magmatic material inside the earth’s crust brings the surrounding rocks under the influence of intense temperature pressure and causes changes in them.
• Geodynamic Forces:The omnipresent geodynamic forces such as plate tectonics also play an important role in metamorphism.
