Planet Overview - Earth

Earth is the only planet we know of in our solar system that humans can live on. No other planet has oceans, other life forms, and enough oxygen to comfortably breathe. Because we have so much water, Earth is called the Blue Planet. From space the oceans combined with the atmosphere makes the planet look blue.

Earth - What It's All About

About 71 per cent of the Earth is covered with water. Earth is the only planet where water can exist in liquid form on the surface. Even though we have water coming out of our ears, only one percent of it is drinkable. Most of it is frozen or salty. Earth is the fifth largest planet and the third planet from the Sun with only Mercury and Venus being closer. It's about 24,920 miles around Earth at the equator. That means it would take 33,000,000 people holding hands to reach all the way around. The land on Earth is made of several plates and at one time all of these plates were joined together, making it possible to walk from one side of the Earth to the other. Plates are individual pieces that are always moving so the land keeps drifting apart slowly. Today there are seven distinct land masses known as continents.

Earth - Fun Facts

  • A thousand tons of meteor dust falls to Earth every day.
  • Only 11 percent of the Earth's surface is used to grow food.
  • Wind carries over 100 million tons of sand grains around the Earth every year. That means if you live in the United States, you could have sand from the Gobie desert in China reach you.
  • Antarctica is the coldest place on Earth. The entire continent is made of ice.

@AlphaT  You've posted on behalf of everyone else. In their style. XD Now no one needs to post. God bless you for ending a thread in which everyone would post the same opinion and say the same thing. XD

I found the greatest riddle ever (credits to Ted-Ed), and I want to see if anyone can solve it without looking up the answer. THE RIDDLE OF THE ALIEN OVERLORDS. You and your team have crashed-landed on an ancient planet. The only way off is to appease its three alien overlords, TEE, EFF, and ARR, by giving them the correct artifacts. Unfortunately, you don't know who is who. From an inscription, you learn that you may ask three yes or no questions, each addresses to any one lord. Tee's answers are always true. Eff's answers are always false.  And Arr's answers are random. But, there's a problem. You've deciphered the language enough to ask any question, but you don't know which of the two words 'ozo' and 'ulu' means yes, and which means no. How can you still figure out which alien is which?

Fear: The Emotion of Death   You can't see me, But I'm there. I'm in your tears, I'm everywhere. I stalk you in your shadow, So stealthy and no slack. I'm made of dark matter, You better watch your back. You can hear me, I'm your beating heart. Inside is emptiness, Tearing you apart. You shiver and shake, At the sound of my name. I engulf you, drown you, Surround you with shame.   I've seen destruction, More than anyone. I'm darker than, The world with no sun. The agony arises, There's so much red. Most of it coming, From the dead. I become your shadow, I'm a terrible sight. And when you see me, You're frozen with fright. I'll grab you by your neck, You'll be thrashing around. You're crying, shrieking, Until there's no sound.   I feel so sad, So empty, so. . . Alone. So you'll feel the same, You'll be on your own. And as long as you are with me, At the point of no return. You will go crazy. You'll crash and burn.   Then you understand, With your slowing of breath. That I am Fear, The Emotion of Death.
