How long is the earth's circumference?
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.

How does salt help preserve meat?
Salting, especially of meat, is an ancient preservation technique. The salt draws out moisture and creates an environment inhospitable to bacteria. If salted in cold weather (so that the meat does not spoil while the salt has time to take effect), salted meat can last for years.

Which planet has the hottest surface temperature?
Venus, the second closest plant to the Sun, has the highest average temperatures of any planet in our Solar System, regularly reaching temperatures over 460°C. Venus is so hot because of its proximity to the Sun and its thick atmosphere.

Which planet has the most satellites?
Eight of Jupiter's moons are regular satellites, with 4 large, spherical moons, and 4 smaller moons that orbit closer to Jupiter. Jupiter has an additional 55 tiny irregular satellites. The planet with the second highest number of moons is Saturn, with 61 moons.

How many dogs years are in 1 human year?
But the conventional wisdom that one dog year equals seven human years is an oversimplified view of how old your dog is in human years. Although a dog's age averages out this way, there is quite a bit of variation. For example, dogs mature more quickly than children in the first couple of years.

What country has the Gobi desert in it?
The Gobi is a large desert region in northern China and southern Mongolia. The desert basins of the Gobi are bounded by the Altai mountains and the grasslands and steppes of Mongolia on the north, by the Tibetan Plateau to the southwest, and by the North China Plain to the southwest.

What are the colors of the rainbow?
The colors of the rainbow in order are red, orange, yellow, green, blue, indigo and violet. A good way to remember it is ROY G. BIV. My five year old knows the correct way of which the colors of the rainbow goes. I've never seen a rainbow start with violet.

What are our five senses?
The nervous system has a specific sensory system or organ, dedicated to each sense. Humans have a multitude of senses. Sight (ophthalmoception), hearing (audioception), taste (gustaoception), smell (olfacoception or olfacception), and touch (tactioception) are the five traditionally recognized.

How long is a kangaroo baby when it is born?
The young kangaroo, or joey, is born alive at a very immature stage when it is only about 2 cm long and weighs less than a gram. Immediately after birth it crawls up the mother's body and enters the pouch. The baby attaches its mouth to one of four teats, which then enlarges to hold the young animal in place

Can there be thunder and lightning without rain?
Dry thunderstorm refers to thunder and lightning that occur without bringing rain to the ground. In fact, the thunder-bearing clouds do produce rain but the rain droplets have evaporated in the air before reaching the ground.

Why does water boil faster with salt?
If you look at the heat capacity of salt water, you will find that it is less than pure water. In other words, it takes less energy to raise the temperature of the salt water 1°C than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first.

Can Animals Dream?
In fact, they concluded that animals can have very complex dreams that include memories or replays of events that happened while they were awake. The researchers studied rats that had been trained to run on a track. They mapped and measured brain activity with electrodes while the rats were awake and running.

What do the 5 rings of the Olympic symbol represent?
The rings of blue, black, yellow, red and green, which make up one of the most recognized symbols in the world, traditionally represent the five different areas of the world involved in the Olympics (North and South America are considered one area, along with Africa, Australia, Asia and Europe).

What percent of the population is ambidextrous?
About 90 percent of people are right-handed, says Corballis. The remaining 10 percent are either left-handed or some degree of ambidextrous, though people with "true" ambidexterity—i.e., no dominant hand at all—only make up about 1 percent of the population.
