4 interesting facts about plate tectonics

feat1

The earth’s surface is divided into tectonic plates. It is part of the earth’s rigid outer layer called lithosphere. There are 16 large tectonics plates and many small plates. The land in our earth is not fixed. It is constantly moving. We hardly notice the movement as it is very slow. It moves about one to six inches every year. Here are some interesting facts about plate tectonics.

Presence of tectonic in the universe

1

According to the experts, tectonic is present in the other parts of the universe as well. In 2005, Huygens Probe took the pictures of Titan, then largest moon of the planet Saturn. The tectonic activities of the moon were evident in the pictures.

Three types of tectonic boundaries

Three types of tectonic boundaries are created due to the movement of the plates. The convergent boundary forms where plates move into one another; divergent occurs when the plates move apart, and transform takes place when the plates move sideways to each other.

Volcanos show evidence of tectonics

3

Mountains and hills that are formed due to volcanos show that tectonics is present. Many mountains look as if a deck of cards is folded up. Some areas of rocks are at a different angle than the others. This happens because plates push each other.

Mid-Atlantic Ridge

The Mid-Atlantic Ridge at the center of the Atlantic Ocean pulls apart every year. The opening lets magma leave the place. There is volcanic activities underwater as the plates pull apart.

Geological experts have carried out various researches on tectonic plates. It is a wonder how our earth’s surface moves. We might find more interesting information about tectonic plates movements in future.

4 warning signs of volcanic eruption

Scientists monitor volcanic activities to predict when volcanos might erupt. This will help to save many lives and properties. It is easier to forecast the eruption of dormant volcanoes. It is more difficult to forecast the eruption of an active volcano, as there is the constant emission of gasses and seismic activities are also going on continuously. Scientists are still working on it, and they have come with some signs that may indicate volcanic eruption.

  • If an active volcano is quiet for a long time, then it’s an indication that it will erupt soon. Researchers tracked 50 explosions in the Telica Volcan in Nicaragua and found that 35 of them were preceded by quiet period. The quiet periods lasted from six minutes to more than ten hours.
  • Seismicity is the most common way of monitoring volcanic eruption. If there is an increase in seismic activity on a quiet volcano, then it’s an indication of volcanic eruption.
  • By studying ground deformation, you can tell whether a volcano will erupt soon or not. The changes in surface can be measured using various techniques.
  • You can also predict volcanic eruption by monitoring the gasses that come out of it. If you see any anomalous increase in temperature of the gasses, then it is an indication of volcanic eruption.

Satellite data is now used to monitor volcanoes. You can obtain thermal images of volcanic areas with the help of the satellite. Making a more accurate prediction about the volcanic eruption in future is possible.

3 major archeological discoveries of recent times

feat3

Archeologists are always moving around the world to make interesting discoveries about the past. In recent years, there have been some interesting discoveries that have stunned people. Here are three major archeological discoveries made in the last few years.

Hidden Chambers in Tut’s Tomb

7

Two hidden chambers were found inside the Egyptian pharaoh Tutankhamen’s tomb. The chambers were sealed for millennia. The site was overlooked by Howard Carter in 1920. When Egyptologist Nicholas Reeves was looking at the laser scans of the tomb, he found the doors to the chambers. Radar scanning and thermal imaging suggest the presence of empty spaces. It is assumed that the burial chamber of Queen Nefertiti is behind one of the walls.

Unlooted grave of wealthy warrior in Greece

8

An unlooted grave of a wealthy warrior was found in the southwester Peloponnese. There were many traditionally female grave goods buried with the warrior. Combs, beads, mirror, etc. were found. There were many precious pieces of jewelry.

Treasure on Sunken Spanish Galleon

It is told to be the most valuable shipwreck ever. This Spanish galleon laden has about one billion dollars worth of precious gems and metals. Many people are claiming for their part in the discovery of this ship. Columbia’ president said that his country had located the ship. A private U.S. salvage firm Sea Search Armada is claiming that it found the wreck 30 years ago. Even Spain is claiming about the ship. So, there might be a huge fight regarding this matter soon.

These discoveries are amazing. The archeological experts are working harder to find more discoveries that might reveal much interesting information about our past.
