3. What is Kangri?
As winter tightens its icy grip on the Kashmir valley, the traditional fire pot known as “Kangri” is seeing a surge in demand.

About Kangri:

  • The Kangri, also known as Kanger or Kangid, is earthenware filled with glowing embers and encased in pretty handmade wicker baskets.
  • It is a portable and moving heater that Kashmiris keep in their pheran, a long woollen cloak reaching down to the knees worn by people during the frosty winters.
  • A pot can hold about 250 grams of charcoal, and the fire, lasts for hours, under a pheran.
  • It keeps people warm during the harsh winter months, when temperatures can drop below minus 20 degrees.
  • How is it made?
  • It is known for its outer shell made of willow wicker reeds that grow abundantly in the wetlands of north Kashmir’s Ganderbal district. 
  • These reeds can reach eight feet in height and are harvested during autumn, just before demand for the fire pots swells. 
  • These then go through a multi-layered process of scraping and peeling to get rid of the bark, soaking, boiling, and drying before they are ready to be woven around a bowl-shaped clay pot.

8. Picocystis Salinarum
Recently, a young researcher has divulged the secret of how the Picocystis Salinarum survives the harshest of conditions by resorting to physiological adaptation to highly saline-alkaline/hyperosmotic conditions.

About Picocystis Salinarum:

  • It is a globally widespread picoplanktonic green algae of saline lakes. 
  • It is one of the smallest green algae.
  • It is found in hypersaline soda lake Sambhar, Rajasthan, to survive extreme environments. Though the algae had been widely found in saline-soda lakes around the world, it was spotted for the first time in India only in the Sambhar Lake.
  • The unique organism apparently enhances photosynthesis and ATP synthesis along with chaperone proteins as key response to high salinity-alkalinity.
  • Enhanced photosynthetic activity exhibited by P. salinarum in highly saline-alkaline condition is noteworthy as photosynthesis is suppressed under hyperosmotic conditions in most photosynthetic organisms.

Key facts about Sambhar Lake

  • It is India's largest saline wetland located in Rajasthan.
  • It is a ephemeral salt lake,
  • It is also a designated Ramsar Site (recognized wetland of international importance).
  • It represents the depression of the Aravalli Range.

What are volcanoes?

  • Volcanoes are openings, or vents where lava, tephra (small rocks), and steam erupt onto the Earth’s surface.
  • These can be on land and in the ocean.
  • They are, in part, a result of their own eruptions but also the general formation of our planet, as tectonic plates move.

What is a stratovolcano?

  • It is also called a composite volcano.
  • This volcanic landform is characterized by a conical shape formed by layers of volcanic material deposited during successive volcanic eruptions.
  • These volcanoes tend to slope gently at the base but rise quickly near the summit to form tall mountain peaks.
  • They are typically found above subduction zones, and they are often part of large volcanically active regions, such as the Ring of Fire that frames much of the Pacific Ocean.
