A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents.

By Oliver, Grahame J H Wilde, Simon A; Wan, Yusheng Abstract: Thirty-seven granitoids from Scotland have been dated using the sensitive high-resolution ion microprobe zircon method. Granitoids were intruded during: (1) crustal stretching at c.

A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place.

You know Earth's schematic: core, mantle, crust, right? Sorry, not so simple. Like the gooey center of a chocolate morsel harboring peanut butter and honey, inner Earth is far more nuanced than outward appearances would suggest.

The Earth's crust is, on global average around 40 kilometers deep. In relation to the total diameter of the Earth with approx. 12800 kilometers this appears to be rather shallow, but precisely these upper kilometers of the crust, the human habitat, is of special interest for us.

Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes that helped shape the Earth as we know it today.

Uncovering a rare, two-billion-year-old window into the Earth’s mantle, a University of Houston professor and his team have found our planet’s geological history is more complex than previously thought.

New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium.

Patterns of scalloped-edged cliffs or lobate scarps on Mercury’s surface are thrust faults that are consistent with the planet shrinking and cooling with time. However, compression occurred in the planet’s early history and Mariner 10 images revealed decades ago that lobate scarps are among the youngest’ features on Mercury. Why don’t we find more evidence of older compressive features?

Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
