Cuando las olas golpean las dunas con vegetación, se forman áreas anegadas frente a las plantas, lo que facilita que la arena sea arrastrada por la corriente más fácilmente. Sin embargo, las plantas aún son necesarias para formar las dunas en primera instancia.
Laboratory experiments suggest that underwater gas eruptions—due to the venting of gas hydrates, for example—could trigger the formation of layers of suspended sediment in the ocean.
When waves hit vegetated dunes, waterlogged areas form in front of plants, making for sand that’s easier to wash away. But you still need plants to form dunes in the first place.
Changing environments can dramatically change how quickly layers form in sedimentary rocks, leading to incorrect time estimates.
Lab experiments on pieces of granite reflect natural aftershock dynamics and highlight the role of rock roughness along a fault.
For the first time in more than a century, scientists have identified new sodium chloride crystals. The discovery may reconcile puzzling spectroscopic images of Europa’s surface.
For the first time, scientists have redirected lightning using a laser beam. And that’s just the start of what’s possible.
In the small-scale details of grain shape, researchers have found a new way to understand how sediment flows in a river, a process shaping Earth’s landscapes.
Foraging in hotter-than-desired temperatures could negatively affect ants’ biology and the forest ecosystems that they support.
Manganese oxides are thought to be a signature of atmospheric oxygen. But on the Red Planet, recent results suggest they might be more of a red herring.
