TOP 10 Recent Discoveries in Earth Science

 Here are 10 recent discoveries in geology that have had a significant impact on the field: 1. In 2021, scientists discovered a new type of crystal deep inside a volcanic eruption in Russia. The crystal is made of a rare mineral called petrovite , which had never been seen before. 2. Earth's oldest rock was discovered in western Greenland in 2020, dating back to 3.7 billion years ago. The rock provides important information about the early stages of Earth's formation. 3. Researchers discovered a massive underground aquifer beneath the driest desert on Earth, the Atacama Desert in Chile, in 2020. The aquifer could provide a sustainable source of water for the region. 4. In 2019, scientists discovered a new type of deep-sea hydrothermal vent system in the Atlantic Ocean. The vent system is unique because it is powered by seawater rather than magma. 5. A massive crater, measuring over 30 kilometers in diameter, was discovered beneath the ice of Greenland in 2019. The impact that ...

History of our Earth :

Image
History of our Earth :   Some 4.6 billion years ago, a giant cloud of gas, called a nebula, collapsed into itself because of its mass and crushed all the gassy material in it into a plane, even as it was constantly spinning. This disc of material is called the protoplanetary disc. Over a period of a hundred thousand years after the collapse, the Sun was formed at the center of this disc, with the rest of the nebular gas swirling around it. Nearly 98% of this gas was just hydrogen and helium. (Our Sun constitutes 98% of the mass of our Solar System today.) Gases and other materials in this protoplanetary disc outside of the Sun started clumping together at various spots. Constant collisions between these bodies formed miniature planets, called planetesimals. These planets eventually grew in size by pulling more material in due to growing gravitational forces, a process called  accretion , to become true planets within 100,000 years after the Sun’s formation. The gas gia...

Rocks:

What is a rock? Mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable quantities in nature, as by the action of heat or water Rock Types Scientists are always looking for ways to put things into categories, and rocks are no exception.  Rocks  are solid masses occurring naturally as part of our planet. As it turns out, rocks can be put into three fundamentally different types: Igneous rock Sedimentary rock Metamorphic rock Igneous Rocks Igneous rocks  - for example, basalt and granite - are crystalline solids that form directly from cooling magma. Magma  is molten rock made by the partial melting of rocks in the earth's interior under conditions of high temperature and high pressure. As rock melts, it becomes less dense and rises towards the earth's surface. Magma that reaches the earth's surface is called  lava . Most lava flows are quiet, but some can be violent, such as the eruption o...

What does a geologist do?

Image
What is a Geologist? A Geologist is a detective solving the complex mysteries of the earth, finding clues from millions of years old rocks. They have the power to imagine the unimaginable and look beyond the past and the future. A Geologist is a specialized type of Scientist Also known as:  Geophysicist ,  Geohydrologist ,  Earth Scientist . Geology is a study that encompasses all the materials that make up the earth, the forces that act upon the earth, as well as the biology of ancestral inhabitants based on fossil records. A geologist is someone who works to understand the history of the planet we live on, to better predict the future and explain current occurrences. A geologist studies earth processes such as earthquakes, landslides, floods, and volcanic eruptions to survey land and draw up safe building plans. When geologists investigate earth materials, not only do they investigate metals and minerals, but they also look into oil, natural gas...

Branches of geology :

Geology can be divided into several fields, which can be mainly grouped under physical and historical geology. Physical Geology Physical geology includes: Mineralogy - the study of the chemical composition and                              structure of minerals. Petrology - the study of the composition and origin of                               rocks. Geomorphology - the study of the origin of landforms and                                   their modification by dynamic                                                     processes. Geochemistry - the study of the chemical composition of       ...

What is Geology?

Image
Geology is the science that studies Earth : how it was born, how it evolved and how it works.                      Geology is not only the study of rocks, but also the study of how they change. Geology often gives clues about the history of the Earth.
