Fun Earth Facts

Looking for fun Earth facts? Whether you need unique facts for a science report or to impress friends with random trivia, "Planet Blue" (or what some astronomers call Earth) provides number fun Earth facts to use.

Fun Earth Facts

Technical Fun Earth Facts

Fun Earth facts based on different measurements about Earth and about different terrains located on the planet sometimes boggle the mind.

  • Measured at the Equator, the circumference of the Earth is nearly 25,000 miles. The diameter of the earth is 8,000 miles.
  • The Earth is 70% water and of that percentage, almost 97% is salt water while the rest is fresh water.
  • The highest and lowest point on Earth is Mount Everest at 29,029 feet above sea level and the Dead Sea at 1,302 below sea level respectively.
  • The top three elements the Earth is made of are Oxygen (47%), Silicon (28%) and Aluminum (8%).
  • The longest river on Earth is the Nile River, which runs a little over 4,000 miles long.

Recycling

Recycling centers exist across the globe, allowing manufacturers to reuse certain materials. Did you know the Earth has natural breakdown capabilities? Unfortunately, the amount of time it takes for the Earth to recycle products is much longer than the manmade factories, which is why biodegradable products are available.

  • Plastic and aluminum items need 500 years to break down.
  • Anything made from organic materials need 6 months.
  • Paper and cotton also require 6 months.

The Blue Planet

Many Earth scientists, astronomers and astronauts call Earth the Blue Planet. The reason is since the Earth is made of mostly water, the liquid blends in with the atmosphere to make the plant blue.

The Earth is not a perfect sphere. Melting glaciers push water near the equator, making the planet heavier in the middle. As the Earth rotates, the gravity pulls the Earth in the middle, giving it a pumpkin appearance.

Just like the moon, the Earth goes through phases. The Mars Global Surveyor captured these different phases as the Moon and the Earth orbited the Sun.

Other Fun Facts

People aren't the only things on Earth that like to travel. The islands of Hawaii shift towards Japan about 10 centimeters each year. The reason is that Japan and Hawaii are housed on two separate tectonic plates.

Throughout Earth's history, most of the land volcanoes—totaling about 550-- have erupted at least once. It is unknown how many volcanoes exist under the sea.

Almost all types of rocks on Earth sink in water. There is one kind of rock that floats. Pumice is a volcanic rock that is gaseous enough for the rock to float.

Did You Know?

When mud flows, it can reach speeds of up to 100 mph.

When you compare the moon and the Earth, you might wonder why the Earth does not have as many craters as the moon. Earth is a constantly changing environment. Weather, erosion and volcanic activity continually change the Earth's surface. The moon's environment does not have the volatility as the Earth so anything that changes on the moon's surface stays there for a much longer time. Some craters on the moon are over a million years old due to space debris and asteroids crashing into the surface.

Rivers live in the fact that Earth gives birth to them; the rivers can grow in size and eventually die out.

How Will the Earth Age?

Even though it will take a few billion years, the Sun will swell large enough to eventually swallow the Earth. It is very possible that the heat will just melt the Earth. There is a theory that the Sun's density and gravity will just push the Earth into a different orbit. For a man-made solution, scientists have created a calculation that would be able to move the Earth if needed.
