Science & Technology Current Affairs MCQs
1. What is the term that denotes the difference between incoming and outgoing solar radiation?
[A] Energy Difference
[B] Earth Energy Imbalance
[C] Energy Trade
[D] Energy Deficit
Show Answer
Correct Answer: B [Earth Energy Imbalance]
Notes:
Earth Energy Imbalance is the difference between incoming and outgoing solar radiation. It is the indicator of climate change as it provides an estimate of how much, how fast and where the Earth’s temperature is increasing.
A new study has found that around 381 ZJ of heat has accumulated on the Earth from 1971-2020 due to anthropogenic emissions. This is approximately equal to EEI of around 0.48 watts per square meters.

[A] Melting of Earth’s ice sheets
[B] Sun’s Temperature
[C] Moon’s Temperature
[D] Melting of Mars’s ice sheets
Show Answer
Correct Answer: A [Melting of Earth’s ice sheets]
Notes:
The Ice Sheet Mass Balance Intercomparison Exercise (IMBIE) issues regular reviews of the state of the planet’s ice sheets.
It is supported by the US and European space agencies. As per the scientists, mass loss from Greenland and Antarctica is now responsible for a quarter of all sea-level rise.

[A] Right mean square
[B] Root mean square
[C] Right meter square
[D] Root meter square
Show Answer
Correct Answer: B [Root mean square]
Notes:
Scientists from the Indian Institute of Astrophysics (IIA) have proposed a new metric called the root mean square (rms) granulation contrast.
Its purpose is to quantify the image quality of ground-based solar telescopes.
8. Which super-computer was ranked at 75th position at Top 500 Global Supercomputing List?
