“Earthquakes (are) directly the cause of plate tectonics,” Hua said. Plate tectonics is the movement of the plates that make up the Earth’s crust. “It’s just kind of like a boat, like traveling on water.” The plates float on the asthenosphere, a layer of the Earth’s upper man...
“It’s richer in iron than Venus or Earth or Mars.”One story is that Mercury was hit by a large object early in its history. The hitting took away its outer layer, leaving the planet as a big iron core. But no one can be sure that such an event ever happened.“It’s not ...
“ Nobody knows why Mercury sticks out that way," says Joshua Winn, a scientist at Princeton University. “It's richer in iron than Venus or Earth or Mars. "One story is that Mercury was hit by a large object early in its history. The hitting took away its outer layer(外层), ...
The earth is divided into four layers and the crust is its top layer. In the next section, we would look at the layers in more depth. On Earth, in part of the crust, the world is broken into chunks called continents. Before the discovery of Zealandia, four, five, six and seven ...

Also, those samples hold secrets of the sun. Unlike Earth with its protective magnetic field, the moon has been exposed to the bombardment of solar wind. So particles ejected from the sun will be buried in different layer of lunar soil. ...

They were indeed cracks, reminiscent of where the fluid had ...
In subject area: Earth and Planetary Sciences The mission New Horizons showed that the small satellites of Pluto P2 Nikta, P3 Hydra, P4 Kerberos, and P5 Styx did not reach the state of synchronous rotation in the tidal evolution of rotations and have significant inclination angles of the rotat...
Geoscientists first suggested that the Earth's core might have an additional, imperceptible layer about 20 years ago, according to a news release. Now, using new data sets collected by measuring the seismic waves of earthquakes as they passed through the Earth's center, researche...
(21.4–17 MY), constraining the age of the plant fossils that occur immediately below it. We discovered a fossiliferous plant layer, approximately 10 cm thick within the intermediate unit (Figs.2f,g, Supplementary Fig. 5), that consisted of dense mats of leaves, suggesting an allochthonous ...
