This is true. Under unfavorable conditions, such as extreme drought or cold, snails can enter a state of dormancy (estivation) that can last up to three years to survive. They seal themselves in their shells with a layer of mucus.

There are more trees on Earth than stars in the Milky Way.
π‘ Explanation
This is actually true! Estimates show there are approximately 3 trillion (3,000 billion) trees on Earth. The Milky Way, our galaxy, is estimated to contain between 100 and 400 billion stars. Thus, trees significantly outnumber the stars in our own galaxy.

Water can exist as a solid, liquid, and gas simultaneously at a specific point.
π‘ Explanation
This is true and is called the triple point. At a specific combination of temperature (0.01 Β°C) and pressure (6.117 millibars), water can exist simultaneously as ice, liquid water, and water vapor in thermodynamic equilibrium.

The Sahara is the world's largest desert.
π‘ Explanation
The Sahara Desert is the largest hot desert in the world, but if you consider the definition of a desert as an area with very low precipitation, Antarctica is technically the world's largest desert. Its polar desert is significantly larger than the Sahara.

Male seahorses carry the eggs until they hatch.
π‘ Explanation
Seahorses are unique among animal species as the male is the one who becomes 'pregnant' and carries the eggs in a pouch until they hatch, rather than the female. This is a rare example of reversed gender roles in the animal kingdom.

Polar bears can get too hot and overheat if they run too much.
π‘ Explanation
Yes, that's right! Polar bears have such thick fur and a thick layer of fat that they are incredibly good at staying warm in cold environments. But this also means they can easily get too hot if they exert themselves too much.

Bananas grow on trees.

A rainbow is actually always a full circle.
π‘ Explanation
From the ground, we usually only see a half-circle. But if you were high up in an airplane with the sun behind you, you could see that a rainbow actually forms a beautiful full circle!

All clouds are white.
π‘ Explanation
No, that's not right! Clouds can be white, grey, or even dark grey, almost black. When clouds get thicker, they hold more water, which means less light can pass through them, making them look darker. Dark clouds often mean rain is coming!
