New Data Hint at Why Earth Hums and Mountains Rise
Article Abstract:
Researchers are coming up with two new theories on the Earth's properties. One is that river erosion may contribute to the growth of mountains. The other is that the Earth has a constant but inaudible hum that is exacerbated by the wind. In the first theory, researchers found that the Indus River may be causing one of the Himalayan mountains to grow by weakening the Earth's crust and allowing hot rock to push the mountain upward. The second theory was validated through the correspondence of storm patterns to Earth hum intensity in seismic tracking.

Early Life Thrived Despite Earthly Travails
Article Abstract:
The first 2 billion years of Earth's history are the most mysterious, yet would reveal the most about the origins of life. Many researchers are taking a geologic approach to try to understand this early epoch, and are making new discoveries about early life.
