Malaysia starts cloud seeding to induce rainfall

The video explains the process of cloud seeding conducted in Simbalan, Malacca, and Johor on March 3rd. It describes how aircraft are used to spray sodium chloride solution at the base of clouds. The sodium chloride particles are carried upwards by warm air currents, where they interact with water molecules, forming droplets. This process takes at least 15 minutes for the clouds to become heavy enough to produce rain.

Which regions were mentioned as locations for cloud seeding on March 3rd?

• Kelantan, Terengganu, and Pahang

• Kuala Lumpur, Penang, and Selangor

• Simbalan, Malacca, and Johor

What is used to carry the sodium chloride solution for cloud seeding?

• Helicopter

How many liters of sodium chloride solution are used in the cloud seeding process?

• 500 liters

• 1000 liters

• 1500 liters

What happens to sodium chloride particles when they are carried upwards by warm air currents?
