Up in the air – A quick quiz

By

Here are 5 fresh questions to juggle for this week’s quiz. Will you score high, or come crashing to Earth?

#1. What colour is the sky during the daytime on the Moon?

The blue sky on Earth is caused by light scattering through air. There’s no air on the Moon, so the sky is always black.

#2. Which bird has the widest wingspan?

The largest wandering albatrosses have wingspans around 3.7 metres. That’s about the same as 2 adults lying end to end!

#3. True or false? Mosquitoes are a type of fly.

True! Mosquitoes are members of the order Diptera (meaning 2 wings), which is the scientific definition of a fly.

#4. A triplane has 3 wings, but how are they arranged?

Triplanes, such as the Red Baron’s Fokker triplane, stack their wings vertically. This gives them lots of lift, but they can’t go very fast.

#5. What effect do clouds have on the temperature at night?

During the day, clouds reflect sunlight back out to space, making it cooler. At night, they trap Earth’s heat near the ground, like a warm blanket.

Was I right?
