2.India’s Biggest Natural Arch
A team of the Geological Survey of India recently discovered India’s biggest natural arch during their survey of coal in Kenduadihi block in Odisha’s Sundargarh district.

Why in News:

  • The state unit of the Geological Survey of India (GSI) has proposed to declare the ‘Natural Arch’ in the Kanika range of Sundargarh forest division, a Geo Heritage Site.
  • If it is done, it will be the biggest natural arch of the country to have the Geo Heritage tag.
  • Apart from the arch at Sundargarh, India has two others- one at Tirumala hills in Tirupati and another at Andaman and Nicobar. However, both of them are smaller compared to the one in Sundargarh.

About India’s Biggest Natural Arch:

  • The Sundargarh natural arch, present in the ferruginous sandstone of the Upper Kamthi formation, dates back to about 184 to 160 million years in the lower to middle Jurassic age. 
  • It is an oval-shaped arch and has a length of 30 metres at the base and is 12 metres high.
  • The alcove of the natural arch has a maximum height and width of 7 metres and 15 metres, respectively. 
  • The natural arch and its surrounding area are a storehouse of different primary sedimentary structures like planner and cross-bedding along with occasional current ripples signifying high energy fluvial environment during sedimentation.
  • Formation: Formation of the natural arch could be due to fault activities and the nature of lithotype, which have enhanced the process of sub-aerial weathering over a long period.

What are Geo Heritage Sites (GHSs)?

  • Geoheritage sites are sites of rare and unique geological, geo-morphological, mineralogical, petrological, and paleontological significance, including caves and natural rock sculptures of national and international interest.
  • GSI declares geo-heritage sites/ national geological monuments for protection and maintenance.
  • GSI or the respective State governments take necessary measures to protect these sites.
3.Key facts about Tonga
An earthquake of magnitude 7.2 struck near Tonga in the South Pacific Ocean recently, according to the US Geological Survey (USGS).

About Tonga:

    • In 1970 the former British protectorate acquired its independence and became a sovereign nation, but remains an active member of the Commonwealth.
4.Cerebellum
A recent study has found that the human brain's cerebellum is more vulnerable to Covid infections than other brain regions.

About Cerebellum:

  • The cerebellum, which stands for “little brain”, is a structure of the central nervous system.
  • Location: It is a part of your brain located at the back of your head, just above and behind, where your spinal cord connects to your brain itself.
  • It only accounts for around10% of total brain weight but contains as many as 80% of all neurons in the brain.
  • Functions:
    • Maintaining balance: The cerebellum has special sensors that detect shifts in balance and movement. It sends signals for the body to adjust and move.
    • Coordinating movement: Most body movements require the coordination of multiple muscle groups. The cerebellum times muscle actions so that the body can move smoothly.
    • Vision: The cerebellum coordinates eye movements.
    • Motor learning: The cerebellum helps the body to learn movements that require practice and fine-tuning. For example, the cerebellum plays a role in learning to ride a bicycle or play a musical instrument.
    • Other functions: Researchers believe the cerebellum has some role in thinking, including processing language and mood.

What is Cerebrum?

  • Cerebrum is the largest part of your brain and includes parts above and forward of the cerebellum.
  • It receives and gives meaning to information from the sense organs and controls the body.
  • It is also essential for memory, reasoning, communication, emotions, and many other functions.
  • The cerebellum and brainstem sit below the cerebrum and work alongside it to control the voluntary actions in the body.
5.Export-Import Bank of India (EXIM Bank)

7.Geminid meteor shower
Recently, NASA's Parker Solar Probe mission has shed new light on the origin of the intense Geminid meteor shower.

About the Geminid meteor shower:

  • What it is? It peaks during mid-December each year and is considered to be one of the best and most reliable annual meteor showers.
  • Unlike most meteor showers that originate from comets, the Geminid stream appears to originate from an asteroid known as 3200 Phaethon.
  • New findings
    • The new findings have perplexed scientists as asteroids are not typically influenced by the Sun's heat and should not leave behind a trail.
    • Phaethon is an asteroid, but as it flies by the Sun, it seems to have some kind of temperature-driven activity.
    • The Parker data indicates that a powerful event such as a high-speed collision or a gaseous explosion likely caused the creation of the Geminid stream.

Key facts about the 3200 Phaethon

  • It is classified as an asteroid- the first to be discovered via satellite.
  • It was discovered on Oct. 11, 1983, using the Infrared Astronomical Satellite, and named after the Greek myth of Phaethon, son of the sun god Helios, due to its close approach to Sun.
  • It is blue in colour, which is rare for an asteroid.
  • It orbits the sun every 524 days (1.43 years), coming as close as 0.14 astronomical units (AU) and reaching as far as 2.40 AU from the sun. 
  • Its orbit is highly elliptical. It completes a rotation on its axis every 3.60 hours.
  • It is about 3 kilometres in diameter, making it larger than 99% of asteroids.
8.Enceladus
Recently, NASA's Cassini spacecraft discovers ‘phosphorous on Saturn's moon Enceladus.

About Enceladus:

  • It is the second nearest of the major regular moons of Saturn and the brightest of all its moons.
