Our planet may undergo major changes, which can be seen, our generation, starting from the formation of new islands in the oceans, earthquakes and eruptions, before breaking off huge chunks of ice.
Some of the fast geological transformations attracted the attention of scientists and instill fear in the hearts of many.
1) New Coast
Earthquakes are not only made to move the ground under my feet, but they can dramatically change the landscape. Earthquake in Chile February 27, 2010 changed the landscape of the country, raising the ground on more than 2.5 meters off the coast, dropping a piece of land. Strong aftershocks forced offshore appear on the surface of the ocean, thus raising the coastline in some places to 500 meters.
2) Ice conveyor
Huge ice rivers that form when snow and ice accumulate in one place for thousands of years, acting like a giant conveyor, pushing the ice into the sea. These rivers are moving very slowly, but eventually dumped the ice in the ocean that breaks off as icebergs. This ice is an important source of additional water in the oceans. Of some glaciers icebergs break off more often than once per hour. These glaciers are called "landing", as they rest on the ocean floor, while others float on the surface. Scientists have noticed that the glacier in Alaska Columbia transformed from mundane to float, which slows down its split.
3) The eruption of volcanoes
Massive volcanic eruptions released into the sky a lot of ash and foam. They can be heard for hundreds of miles. Volcanoes change the landscape at high speed because the trigger huge landslides. Thousands of years ago the volcano Soufriere Hills, Montserrat (Lesser Antilles archipelago) caused by severe landslides, which went into the ocean. Area of some of these landslides was 5 cubic kilometers. Breed moved across the ocean floor several miles.
Volcanic dome collapsed, when the lava rose up and came out under pressure. The volcano continues to erupt ever since. In the 1990s, major eruption forced the islanders to leave their homeland.
Landslides can wipe out entire communities in the blink of an eye, if they are associated with volcanic activity. Heavy rains also contribute to the emergence of landslides, as it was near the volcano Elgon in Uganda, March 1, 2010.
Landslides — common in the region, but this was the largest landslide. He buried three villages, killed 83 people, more than 300 missing. The Government of Uganda reported that the destruction of forests has played a role in the formation of such a serious landslide.
When the top of the mountain glaciers are destroyed, they drop an avalanche of snow, ice and rock from the slopes. Strong avalanche descended from Kolka September 20, 2002 in the Caucasus. An avalanche has covered part of the gorge in the valley Genaldon speed of 180 km / h and a portion of the village buried under a layer of ice and rock thickness of 130 meters.
Recent studies have shown that natural disasters like avalanches, floods and heat waves, in mountainous areas are more often due to global climate change. Just as global warming continues to advance, scientists do not rule out that such disasters will occur more often in this century.
6) Rapid flooding
Some of the most spectacular canyons on Earth (and Mars) are likely to have formed almost instantaneously from a geological point of view, according to scientists who have examined the canyons in the heart of Texas. These canyons were formed very quickly. Canyon Lake Goji 7 meters deep formed in just 3 days after the flood of 2002. The flood swept the vegetation, leaving behind a trail of sand color.
One major flooding, which could split the rock, it is very rare, but this flood has helped scientists learn about other events of the past of our planet. Perhaps, like fast floods and other canyons formed in the distant past, when the glaciers melted, releasing large amounts of water. Scientists believe that the cause of the flooding were canyons on Mars.
Most meteorites that are trying to break through to the surface of the earth are burned in the atmosphere. However, the largest of them succeeded, and they changed the look of the world in some places.
Wind, water and vegetation destroyed most of the craters on the planet. Even the largest craters, except for a few, have been destroyed because of the processes of plate tectonics.
Barringer Crater, also known as Meteor Crater, has a diameter of 1300 meters and a depth of 174 meters. It is located in a flat sandy desert 30 kilometers from Vislou, Arizona.
