Scientists have discovered Earth thousands of previously unknown mountains. They are located on the bottom of the ocean – informs livescience.com.

We know more about the surface of Mars than our own planet. The earth still hides many secrets in front of us at the bottom of the oceans. American scientists, using two satellites Jason 1 and CryoSat, decided to look under the surface of the oceans, to check what is on their bottom.

It turned out, our planet is more “wrinkled” than you might think. The group of 5,000 known submarine peaks, each of which has at least 2,000 feet tall, joined by 15,000 new mountains.

According to the researchers, each of these newly discovered peaks is at least 1.5 km in height.

Submarine discoveries are not so simple. There are many techniques that are used to study Earth’s land surface. Ocean floor is covered with a layer of water several kilometers, which blocks access to the electromagnetic radiation – explains one of the authors of the discovery of David Sandwell of the Scripps Institute of Oceanography in the USA.

So how do scientists have looked under a thick layer of water? No, it did not. Wysokościomierzami used the radar on satellites and measured the height of the … oceans. The area of ​​the ocean is not a uniform – are on the subtle hills and dips, which reflect the topography of the seabed and the gravitational field of the Earth.

It is these small differences in the amount of ocean surface allowed the scientists to develop an accurate map of the bottom and discover thousands of new peaks.
