Is the Principle of Original Horizontality a good indicator?
Earth ScienceAsked by: Craig Wiseman What best describes the principle of original horizontality? The principle of original horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. It is a relative dating technique. The principle is important to the analysis of folded and tilted strata. What is the meaning of original
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 )
Water on Mars and Earth
Earth ScienceAsked by: Shawn Wade The ice on Mars is a little bit different than on Earth. On Earth, usually the ice is just, you know, water ice. But on Mars, it’s actually water ice and CO2 ice mixed with each other. How much water is on Earth vs Mars? The Mars Odyssey neutron spectrometer observations
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
What are we seeing when we see the curvature of Earth?
Energy & ResourcesSo, You Think You Can See the Earth Curve? Let’s Talk About It. We’ve all looked out at the horizon and wondered, right? Is the Earth really round? Despite what some corners of the internet might say, the answer is a resounding yes. But actually seeing that curve? That’s a bit trickier than you might
