This year, scientists have uncovered some of the most well-kept secrets on Earth. They found hidden rivers, part of lost continents and the remains of ancient rainforests, and they entered the ancient history of the planet using cutting edge technologies. Who knows what they will find next! While we wait to discover, here are 10 geological discoveries that will shake our world in 2020.
Hist Historical Abuse at Yellowstone
The Yellowstone hotspot is hidden beneath national park geysers and hot springs, and about 9 million years ago, a volcano erupted. Two historic historical abuses, Scientists found scientists. After analyzing ancient volcanic rocks and volcanic deposits in the area, the team found evidence of two previous unidentified eruptions, which they named McMullen Creek Surprising and Granny Landing Surprising. Records were shattered by the eruption of Gray Landing, the largest explosion at the Yellowstone hotspot to date. About 72.72૨ million years ago, the eruption covered about southern, 900 square miles (4,000,000 square kilometers) with what is now volcanic eruptions in southern Idaho and northern Nevada.
The monster blobs near Earth’s main are more than we thought
The continent-sized blobs of the continents sit at the seams of the Earth’s solid mantle and liquid outer core, and now, scientists believe they may be Even bigger than we imagined. As previously estimated, if pulled toward the planet’s surface, the two largest blobs would measure 100 times taller than Mount Everest. But after decades of studying seismic data on earthquakes, scientists have now speculated that the larger the bottom of the Pacific Ocean could actually be more monsters. For example, a new structure with the edge of a blob has a size of more than 620 miles (1000 kilometers) around it.
The Lost Islands in the North Sea faced a massive tsunami
About 1,000,000 years ago, a tsunami struck the plains between Great Britain and the Netherlands, submerging much of the region. But research suggests there may be some islands Protested the tsunami, Has provided a home to Stone Age humans for thousands of years. Although they remained on the water for a short time after the tsunami, rising sea levels eventually submerged the islands about 1,000 years later. Scientists learned that the lost islands survived the tsunami only after collecting silt from the shores east of the Os River in the English Sea.

The origin of the earth is one billion years old
Earth’s solid interior – 1,500-mile-wide (2,442 km) of iron ball – probably formed 1 billion to 1.3 billion years ago, Scientists estimate scientists. By recreating the conditions seen in the teenage, small-scale core, the team was able to calculate how long it would take for the molten iron fungus to form the current size of the core. The period of about 1 billion years is nicely connected with the historic historical fluctuations in the magnetic field of the window planet, which became significantly stronger 1 billion and 1.5 billion years ago. This increase in magnetism could be due to the crystallization of the inner core, as the process would have released heat into the liquid outer core; The heat drives a churning motion in the liquid which then powers the magnetic field.

Part of the Lost Continent under Canada
About 1,150 million years ago, the now-lost continent became very large pieces – and only recently has a large part been found. Hiding under Canada. Scientists made the discovery while studying a diamond-bearing volcanic rock called Kimberbite, which was collected about 250 miles (400 km) below Baffin Island in northern Canada. Kimberlight’s mineral chemistry matched that of the long-lost continent, making the location of the sample the most important issue where evidence of the continent was found.

Underwater rivers found near Australia
This year, scientists Find huge rivers Cold, freshwater water that flows deep into the deep sea off the coast of Australia. Rivers are discovered by researchers using autonomous underwater vehicles when the shallow water temperature of the coast decreases during the winter. Evaporation during the summer months makes this shallow water saltier than cold water, so when it cools, the ganse, the salt water, sinks and sinks as a river of water from the ocean. These rivers spread thousands of miles and carry nutrients, plants and animal substances and pollutants into the ocean.

Ancient rainforest under Antarctic ice
Antarctica may be the last place you expect to find Remains of an ancient rainforestBut scientists have found exactly the same thing on the west side of the continent. The remains of the forest were found in a silt core carved off the coast near the Pine Island Glacier. One layer of silt inside the root stood out from the rest, as its color is clearly different from that of those around it; On closer inspection, scientists found a network of ancient pollen, spores, bits of flowering plants, and roots within the layer. For the mid-Cretaceous period, when the now frozen Antarctic had a mild climate, the sampling time was 900 million years.

Ancient seabed is buried 400 miles below China
Was once found buried at the bottom of the Pacific Ocean Hundreds of miles below China, Where it continues to descend towards the Earth’s mantle transition zone. The rock slab once sat on the outer layer of the Earth’s surface, the top of the marine lithosphere, but was pushed downwards when it collided with a neighboring tectonic plate, called a subduction phenomenon. Scientists did not detect any subduction in the depths of 254 to 410 miles (410 to 660 km) below the Earth, in the depths below the surface of the planet.

Is the lost tectonic plate resurrected?
Scientists are digital Reconstruction of tectonic plate And showed that its movement gave birth to a volcanic arc in the Pacific Ocean about 60 million years ago. In the past, some geologists have argued that the plate, known as the resurrection, does not exist. But if it had existed, the plate would have been pushed beneath the Earth’s crust millions of years ago; So using computer reconstruction, scientists reversed that motion, virtually pulling it and other ancient plates back to the surface. They found that the resurrection just east of the two plates, Cula and Faralon, would fit like a complete puzzle piece, with its edges matching the ancient volcanic belts of Washington State and Alaska.

The main coral structure dwarfs the Empire State Building
This Separate the first coral reef It stands taller than the Empire State Building, discovered over 100 years. Measuring 1,640 feet (500 m) high from base to peak, the Coral Tower stands freely near the rest of the Great Barrier Reef off the coast of Australia. The blade-like structure measures 1 mile (1.5 km) wide at its base and its top sits about 130 feet (40 m) below sea level.
