Choose the incorrect statements:
Correct
Solution (d)
Statement Analysis
Statement 1 Statement 2 Correct Correct · A gigantic ocean lying 700 kilometres beneath the Earth’s surface, hidden within a rock called ringwoodite. · This subterranean reservoir, three times the volume of all the planet’s surface oceans combined, was revealed through studies of seismic activity.

Question 4 of 5
4. Question
Consider the following statements about Stellar mass black hole and Supermassive black hole
- Supermassive black holes are formed from the gravitational collapse of a single star or from the merger of two neutron stars.
- Stellar mass black holes have a mass greater than about 50,000 times the mass of our sun.
Choose the correct statements:
Correct
Solution (d)
Statement Analysis
Statement 1 Statement 2 Incorrect Incorrect · Supermassive black holes have a mass greater than about 50,000 times the mass of our sun and are typically millions to billions of times the mass of our sun. · Supermassive black holes are far too large to have formed from the gravitational collapse of a single star.
· However, scientists do not currently know how supermassive black holes form.
· Supermassive black holes are always found at the center of a galaxy and almost all galaxies have a supermassive black hole at its center.
· Stellar-mass black holes are formed from the gravitational collapse of a single staror from the merger of two neutron stars. · Therefore, stellar-mass black holes have masses similar to the masses of stars.
· More specifically, stellar-mass black holes have masses ranging from about 3 times the mass of our sun to about 50 times the mass of our sun.
Context: Astronomers recently spotted the most massive known stellar black hole in the Milky Way galaxy named Gaia-BH3.

Course:
· It originates in the sub-Himalayan mountains of Arunachal Pradesh at an altitude of 1247m.
· After passing through a narrow gorge in Arunachal Pradesh, the river enters the plains of Assam in Dhemaji district, where it flows in braided channels.
· The river finally debouches into the Brahmaputra near Selamukh in Lakhimpur district.
· But after the construction of the embankment over the Kherkutiya Suti of the Brahmaputra, the river confluences with the Subansiri River.
· The total length of the river is 187 km.
· Topographically, the upper partof the basin is hilly (Himalayan range), and the middle part onwards is a plain area.
· Jiadhal is known for frequent changingof its course and devastating floods.
· The Jiadhal River is a classic example of a flashy river and produces floods with a sudden, high dischargeover a short time interval (a few hours to a day) and with a high sediment load and debris.
Context: The tranquil flow of the Jiadhal river is now being disrupted by the harsh realities of climate change.
