The Most Notable Geological Discoveries of the 21st Century

The 21st century has ushered in a new wave of fresh and exciting geological discoveries. Paul Favret looks back at some of these discoveries and comments on their significance here:

• In 2003, scientists discovered what is now known as the Kavachi volcano, which is located off the coast of Papua New Guinea. This particular volcano is one of the most active underwater volcanoes ever found and is constantly spewing forth volcanic material.

• In 2004, scientists discovered a massive undersea canyon that runs for over 3,000 miles along the Atlantic Ocean floor.

• In 2006, scientists discovered an enormous ice sheet that covers an area of Antarctica twice the size of Texas. This ice sheet is so big that it has the potential to raise global sea levels by up to 20 feet if it were to melt.

• In 2007, scientists discovered what is now known as the world's largest volcano. This volcano, called Mauna Kea, is in Hawaii and taller than Mount Everest when measured from its base, Paul Favret notes.

• In 2009, scientists discovered an enormous impact crater that is believed to have been caused by a meteorite striking the Earth about 3.8 billion years ago. This crater, called Vredefort Crater, is in South Africa and is the largest impact crater ever found on Earth.

• In September 2015, NASA announced that it had found evidence of flowing water on Mars. According to Paul Favret, this discovery could be a significant step in the search for extraterrestrial life.

• In February 2018, astronomers discovered an exoplanet that could be habitable. This so-called "super-Earth" is just 11 light-years away from Earth, making it one of the closest potentially habitable planets.

Paul Favret on Why Educational Charity Matters

  The Benefits of Educational Charity, According to Paul Favret charitynavigator.org Education is one of the most essential possessions a person can have in their life.

Paul Favret on Investing in Geology

  Paul Favret Explains Why Geology is a Valued Investment acceleratingscience.com According to Paul Favret, geology is often understood as a course in school. This might elicit some assumptions from people who need to familiarize themselves with geology as a whole. In reality, geology is quite fascinating. The world has a lot to be grateful for because of geologists. Paul Favret explains that without their expertise, the world's economy would have collapsed long ago. This is not hyperbole, especially in this age where getting resources from the earth is of great significance to human life. Economic valuation, Paul Favret says, is a method that experts use to determine the impact of any material found on the planet. This is generally regarding naturally-occurring resources. Geologists analyze ground content for their reports. The analysis leads to accurate assessments of the soil's potential for use. This analysis can pertain to farming, mining, or other economic ac...

Notable Projects Worked on by Geophysicists

scurbatgeophysics.com  Paul Favret explains that geophysics is the study of the physical processes that shape the Earth and its environment. He mentions that, over the centuries, there have been many notable geophysics projects that have helped further our understanding and deepen our knowledge of our planet. Notable geophysics projects include Galileo Galilei using a telescope to observe and record the phases of Venus in 1609, which was one of the first observations that supported the Copernican model of our very own solar system and placed the Sun at the center instead of the Earth. Another is James Cook sailing to Tahiti in 1772 to observe and, amazingly, record a transit of Venus across the Sun. This data was used to help calculate the distance from the Sun to Earth (known as the astronomical unit). Paul Favret points out that projects have become more complex in more recent times. Here are some of them: - The Apollo Moon landing missions, during which seismometers were plac...
