Did you know that Australia is actually wider than the Moon, or that Earth’s longest mountain range lies hidden beneath the oceans? Our planet harbors countless fascinating secrets that most people never learn about in school. Let’s explore the most astounding facts about the remarkable world we call home.
Earth Facts:
The Shape-Shifting Planet
Here’s something that might shake your view of our world: Earth isn’t actually round. While this might sound like a controversial statement, the truth is far more fascinating than any flat Earth theory. Our planet bulges at the equator and flattens at the poles due to its rotation, creating what scientists call a “geoid” shape. Think of it as a cosmic basketball that’s been slightly squished – though these variations are so subtle you can’t see them in photos from space.
Fun Fact Box: If the Sun were as tall as a typical front door, Earth would be the size of a nickel!
Our Planet’s Hidden “Squishiness”
Perhaps even more surprising than Earth’s shape is what lies beneath our feet. While we often think of Earth’s interior as solid rock, it’s actually structured in fascinating layers:
- An inner core of solid iron and nickel (759 miles in radius)
- An outer core of liquid metals (1,400 miles thick)
- A mantle with the consistency of caramel (1,800 miles thick)
- A relatively thin crust (only 19 miles deep on land, 3 miles under the ocean)
The Great Underground Caramel Layer
The mantle’s “squishy” consistency allows for remarkable phenomena:
- Enables plate tectonics
- Powers volcanic activity
- Causes post-glacial rebound (parts of Canada, Scandinavia, and Greenland are still rising from ancient glacier weight!)
Secrets of the Global Ocean
Our planet’s oceans hold incredible mysteries:
- Cover nearly 70% of Earth’s surface
- Average depth of 2.5 miles
- Contain 97% of Earth’s water
- Hide most of Earth’s volcanoes
Did You Know? Hawaii’s Mauna Kea volcano is actually taller than Mount Everest when measured from its underwater base to its peak!

Earth’s Hidden Mountain Range
Surprisingly, Earth’s longest mountain range isn’t the Andes or the Himalayas – it’s underwater! This submarine range in the Arctic and Atlantic oceans is four times longer than the Andes, Rockies, and Himalayas combined.
The Cosmic Dance of Earth and Moon
Our relationship with the Moon is more dynamic than most realize:
- The Moon is gradually drifting away at 4 cm per year
- It’s actually Earth’s largest satellite relative to its host planet’s size
- You could fit 30 Earths between our planet and the Moon
- Scientists believe the Moon formed from a massive collision with early Earth
Fun Fact Box: Australia is actually wider than the Moon! While the Moon’s diameter is 3,400 km, Australia stretches almost 4,000 km from east to west.
