Record heat in Australia: Dome of heat explained

The video explains the development of high pressure systems at altitudes between 3000 to 7600 meters. These systems can persist over regions for days to weeks, causing the air below to sink and compress, heating the lower atmosphere. This creates a heat dome effect, trapping heat and leading to extreme temperatures, such as those experienced in Australia, reaching up to 50 degrees Celsius.

At what altitudes do high pressure systems typically develop?

• 10000 to 15000 meters

• 7600 to 10000 meters

• 3000 to 7600 meters

• 1000 to 3000 meters

How long can strong high pressure systems remain over a region?

• A few months

• A few hours

• One day

• Several days to weeks

What happens to the air below a high pressure system?

• It rises and cools

• It disperses quickly

• It remains static

• It sinks and compresses

What is the effect of the dome created by high pressure systems?

• It causes rain

• It disperses clouds

• It traps heat

• It cools the atmosphere

What extreme temperature has been recorded in Australia due to the heat dome?

• 60 degrees Celsius

• 40 degrees Celsius

• 30 degrees Celsius

• 50 degrees Celsius
