Science and Tech Quiz: IOD, Dial-up, Satellite Launches & Tripledemic
This news covers several scientific topics.
The Indian Ocean Dipole is like a weather pattern in the ocean, influencing rain and temperature.
Dial-up internet used a phone line to connect to the internet, making noise.
India is launching navigation satellites to help with GPS.
A 'tripledemic' is when three viruses, including COVID-19 and the flu, spread at the same time, possibly straining healthcare.
Neutron stars are incredibly dense objects left over from exploded stars that eventually merge.
The Indian Ocean Dipole (IOD) is a climate pattern affecting the Indian Ocean, influencing local weather.
Dial-up internet, using a modem and landline, connected at slow speeds with characteristic sounds.
ISRO will launch three navigation satellites (NVS-03, NVS-04, and NVS-05) for the IRNSS.
A 'tripledemic' refers to the simultaneous circulation of COVID-19, influenza, and respiratory syncytial virus.
