Hot Topic Solar System Earth Geology
Continental Uplift and Biodiversity Cycles
Topic: Geology
Summary: A new study indicates that periodic uplifting of the Earth's continents could be linked to booms and busts in marine biodiversity over the past 500 million years.

Parts of Earth that Survived the Moon-Creation Collision
Topic: Geology
Summary: A new study shows that portions of the Earth's mantle formed when the planet was smaller, and survived the planet's turbulent formation and the collision that led to the creation of the Moon.

Honeycombs and Hexacopters Tell a Story of Mars
Topic: Geology
Summary: Scientists working in the Channeled Scablands in eastern Washington state are uncovering geological information about the region, and gathering data that will help to explain the history of Mars.

What Happened Prior to Snowball Earth?
Topic: Geology
Summary: A new study suggests that geochemical records found in rocks prior to the glaciation event known as 'Snowball Earth' are unrelated to the glaciation itself.

Waiting for Death Valley's Big Bang
Topic: Geology
Summary: Geologists have determined that a half-mile-wide crater in California's Death Valley was formed by a volcanic explosion much more recently than previously thought. Their research also indicates that another, similar explosion could still occur at the site.

Could Siberian Volcanism Have Caused Earth's Greatest Mass Extinction?
Topic: Geology
Summary: New research offers insight into how a massive volcanic eruption in Russia could have contributed to the greatest mass extinction known on Earth.

Seeking a Pot of Geological Gold
Topic: Geology
Summary: Researchers are moving a step closer to solving one of the greatest murder mysteries of all time. It happened roughly 200 million years ago, marking the boundary between the Triassic and Jurassic periods, and the crime scene was the entire planet. In their quest to solve this ancient mystery, a team of scientists has been combing the coast of Northern Ireland for evidence.

Oxygen's Stops and Starts
Topic: Geology
Summary: Based on studies of rock cores, geoscientists have determined that oxygen did not appear in Earth's atmosphere in a single event.

Earth's Early Atmosphere
Topic: Geology
Summary: Scientists have reconstructed the atmospheric conditions of the early Earth by studying the oldest minerals on our planet. The study provides new data that is important in understanding the conditions under which life arose.

Recreating the Center of the Earth
Topic: Geology
Summary: It is easier to visit Mars than the base of Earth's thin crust - but a new instrument is now helping scientists understand the unique matter that exist at extreme temperatures and pressures in our planet's core. The study will help astrobiologists better understand the properties of planets - from earthquakes to magnetic fields.
