Scientists have found something strange under the Sierra Nevada Mountains in California. And, it can change a lot what the Earth looks like in the future.
Earthquakes are usually close to the surface, about 10 to 18 kilometers deep. But recently, the researcher Debora Kilb noticed that about 20 to 40 km underground, about 20 to 40 km.
This is quite unusual, because at that depth, the earth’s crust is normally hot. This is a lot of pressure for the quake to be.
Killb told another scientist, Vera Shult-Palekum, who was already studying the odd rock pattern in the area, CNN said. Together, they used a special method called receiver function analysis to look deep inside the earth.
What he got was amazing. The earth’s crust is peeling in that area. This rare process is called lithospheric founding.
The process of “peeling” under Sierra Nevada may be associated with how the continents were formed long ago.
These conclusions published in geopolitical research papers help scientists to understand how the surface of the mountains and the earth changes over time. It is like a slow pace of deep ground under our feet.
Earth peeling: What does this mean?
If we imagine the earth like a huge, layered onion, the outer layer crust is the cust. This is the land we walk.
Now, that outer layer has begun to separate or slide in separate or other parts.
When the earth’s crust separates, it changes what the land looks like. New mountains or islands can be formed. Sometimes, there are also earthquakes or volcanoes. When the earth’s crust moves, it can also make new land.
Earthquakes occur when stuck pieces suddenly slip. Volcanoes are formed when the hot melted rock survives through the crack.
Mountains like Himalayas rise when pieces of crust push together. Over the years, new land forms in oceans and some oceans become widespread. This is a nature shaping our planet.
