Because massif-type anorthosites don’t form on Earth today, the new evidence linking these rocks to very hot subduction on the early Earth opens new interdisciplinary approaches for understanding how these rocks chronicle the physical evolution of our planet. “This research advances our understanding...
Unsurfable waves Apart from the chemical composition, the team was able to get insight on the seas’ surface waves, as well as hints of tidal effects from Saturn. The waves were small on the bodies of water, hovering around 3.3 millimeters — quite far from surfing conditions. A larger up...

Titan’s upper atmosphere is dense with diverse organic molecules. The molecules can clump together, freeze, and fall onto the moon’s surface — including onto its eerily smooth rivers and lakes of liquid methane and ethane, with waves only a few millimeters tall. ...
根 第二 中的"They have a very unique way of communicating with each other by sending low frequency sound waves, which is even higher than the sound produced by a plane.(它们有一种非常独特的交流方 式,即发送比飞机发出的声音还高的低频声波。 )”可知,蓝 鲸是通过发出声音信号进行相互交流的。
