  • EARTH: MAKING OF A PLANET

STORY OF EARTH

  • The speed at which the Earth travels around the sun is over 100 times faster than the average speed of a commercial aeroplane.

  • The average life expectancy in the United States is now about 78 years whereas for most of human history life expectancy has been just 10 years.

  • Just 0.01% of all creatures that have ever been alive on Earth are still in existence today.

  • Early hominins, ancestors of modern humans, were much shorter than we are today. On average, we now stand 1.4ft taller than our now extinct predecessors.

  • Despite the fact that around 70% of the world is covered by water, only 3% of this water is drinkable. The rest is simply too salty.

  • Argentinosaurus, from the late cretaceous period, is currently considered the largest mammal (and dinosaur) to have ever existed on Earth. It is almost twice as tall as a giraffe and is thought to weigh more than 15 African Elephants.

  • Scientists reckon that 30,000 species are becoming extinct each year. That means that every 20 minutes a species is vanishing off the Earth forever.

  • The average depth of the Atlantic Ocean is equivalent of 4 times the length of the State of Texas, that’s a total depth of 3300m.

  • The length of a Blue Whale, the largest mammal currently in existence on Earth, is over 20 meters long.

  • If all humans on Earth were lined up head to toe, they would stretch to the moon and back 15 times.

  • The Earth has a mass over eighty times larger than the mass of the moon.

  • Your weight is different on other planets, on Mars your weight is a third of that on Earth, whereas on Jupiter it is over double. On the sun your weight would be almost thirty times larger than it is on Earth!

  • It would take almost 350 days to walk non-stop around the surface of the Earth at its equator, a distance of 25,000 miles, if you walked at an average pace of 3mph.

  • Surprisingly, the strongest animal on the planet is the rhinoceros beetle who can lift up to 850 times its own body weight.

  • The length of one day on Jupiter is equivalent to almost half a year on Earth.

  • The largest flying animal was most likely the Quetzalcoatlus. This flying pterosaur who lived amongst the dinosaurs had a wingspan of 12 meters which would have enabled it to soar across vast distances.
