Study finds the 'squishy' outer shell of Venus may be resurfacing the planet

Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus's heat flow mechanism ...

Researchers uncover secrets on how Alaska's Denali Fault formed

When the rigid plates that make up Earth's lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet's surface. Strike-slip faults, such as the San Andreas Fault in California ...

Plate tectonics in the twenty-first century

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth sciences. Although plate ...

California quake occurred in very seismically active region

The big earthquake that rocked the far north coast of California on Tuesday originated in an area under the Pacific Ocean where multiple tectonic plates collide, creating the state's most seismically active region.
