What are the boundary conditions for Navier’s Equations of motion in seismic?
Earth ScienceAsked by: Shawn Wade What is seismic wave equation? 3.1. Seismic wave equation. The 1D time-dependent seismic wave equation in an isotropic and homogeneous medium can be expressed by (Sheriff and Geldart, 1995):(24) ∂ 2 u ( x , t ) ∂ t 2 − V 2 ∂ 2 u ( x , t )

How Hot was the Oligocene?
Earth ScienceAsked by: Ana Gonzalez Oligocene GMSTs were ∼22 to 24 °C (Fig. 3A), thus not significantly different from those of the late Eocene, 23 °C, and >8 °C higher than modern rather than ∼5 °C (e.g., refs. 42, 69). What was the climate like in the Oligocene? During the Oligocene, Eurasian mid-high latitudes were mainly

Climate on Venus after it becomes tidally locked
Earth ScienceAsked by: Michael Hoff What would weather be like on a tidally locked planet? Tidal-locking planets receive very uneven stellar heating because their one side permanently faces their stars and the other remains dark. While the dayside can be warm enough to sustain liquid water, the nightside could be so cold that any gases would
