3. Most of Earth’s oxygen comes from the ocean.
What do people usually think?
When discussing oxygen, we often think of our green forests and jungles as being responsible for breathing out fresh air.
But what if I told you that the large amount of oxygen we breathe in comes from the ocean?
Here is the astonishing reality:
While it’s true that the green part of our Earth plays a vital role in oxygen production, scientists believe that 50% to 80% of all the oxygen our Earth has comes from the ocean!
Our ocean consists of tiny living creatures called phytoplankton. They are microscopic plants.
These microscopic plants are like trees, which use sunlight to generate their food.
Additionally, they capture carbon dioxide from the atmosphere and release oxygen.
This oxygen that they release is the fresh air that we breathe!
Doesn’t it sound awesome that these microscopic plants, phytoplankton, are the greatest oxygen producers on Earth and serve as the lungs of our planet?
4. Earth’s deepest point is deeper than Mount Everest is tall.
What do people usually think?
Since Mount Everest is the highest mountain on Earth, people assume that no part of Earth could be even deeper than its height.
You won’t believe this, but the vertical extent of the deepest point on Earth is greater than the height of Everest!
Here is the astonishing reality:
The height of the tallest mountain, Mount Everest, is 29,031.69 feet (8,848.86 meters).
This is incredibly high!
However, the Challenger Deep is the deepest point on Earth. Located in the Mariana Trench in the Pacific Ocean, this spot has a depth of 35,876 feet (10,935 meters) below sea level.
Hence, if we are going to compute the sheer vertical distance (magnitude) of both from sea level, the Challenger Deep is numerically greater than the height of Mount Everest!
What an extraordinary fact!
5. Gravity isn’t the same everywhere on Earth.
What do people usually think?
People usually imagine that gravity is a constant force and assume that the weight of an object will stay the same no matter where you are.
You might be surprised to learn that our weight changes depending on the location on Earth!
Here is the astonishing reality:
The Earth is an oblate spheroid, and its gravitational strength changes with distance.
Because our planet is not a sphere, all locations directly on the equator will experience a minimal weight difference compared to those in the North and South poles.
Therefore, if your distance from the gravitational center of the Earth is greater, then the pull of gravity is weaker, and as a result, there is a slight weight change.
Indeed, the weight of an object is not constant and depends on your location.
So, our overall weight changes depending on our location on the planet!
What an incredibly mind-blowing fact!
