At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers ...

This study is led by Dr. Jian Lin (Southern University of Science and Technology) and Dr. Fan Zhang (South China Sea Institute of Oceanology, Chinese Academy of Sciences). “Water is crucial to ...

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life. When you ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

Plate tectonics involves the movements of 15 major and 40 minor lithospheric plates. Note that the Indo-Australian Plate is currently separating into two, which ...

The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 to ...
