Why camel is called “the ship of the desert”? Camels are called “the ship of the desert” because of the way they move on the sand. They sway from side to side because they move both legs on one side at the same time, elevating that side. They thus have a ship-like motion which can make the rider feel sick.
Why does the moon follow us when we drive? When we speed along a road, we notice that everything moves past us. Trees, houses, the road, fences – all fly past us in the opposite direction. We naturally expect the moon also to be flying past us. When this does not happen, we have the sensation that it is “following” us. It happens because the distance of the moon from the earth is quite great. So as we move along, the angle at which we see the moon hardly changes. In fact, we could go along a straight path for miles and the angle at which we could see the moon would still be basically the same.swi
. I wonder why swimmers wear swim caps in competition. There are several reasons why swimmers wear swim caps in competition. First, a cap designates which team you swim with so the spectators will know without actually having to know you. Caps also make it easier for coaches to spot members of their team in the water. Second, a cap keeps your head warm. It is very important to keep your body heat in. Third, a cap cuts down on water resistance. It helps you move a little faster in the water. Fourth, it helps you goggles stay in place. And fifth, it helps protect your ears.
I wonder how a crocodile keeps its teeth clean. People use toothpaste and a toothbrush to clean their teeth. But some crocodiles have a bird friend who cleans their teeth and their mouth. This bird is not afraid of a crocodile at all. It hops right into the crocodile’s huge mouth – and pecks away at tiny bits of food stuck in the crocodile’s teeth. Somehow the crocodile knows that the bird is helping it, so it keeps its mouth wide open.
