Is the Principle of Original Horizontality a good indicator?

Asked 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?

Asked 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

Asked 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?

Asked 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

Asked 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?

Asked by: Michael Hoff It is possible to see the effect of the curvature of the earth from sea level (ships disappearing over the horizon). To actually see the curvature directly (ie to be able to see the horizon as an arc, rather than a straight line) requires an altitude of over 50,000 feet. How

Elevation of a point on Earth

Asked by: Corey Liu How do you find the elevation of any point on Earth? 5 websites that find elevation for any point on earth v=fcuQLlSr6kg%3Frel%3D0%26controls%3D0. What is the elevation of a point? When the height of a point is its vertical distance above or below the surface of a

Where does the 2015 Nepal earthquake rank amongst earthquakes since 1900?

Asked by: Corey Liu What was the 2015 Nepal earthquake magnitude? The Gorkha Earthquake in Nepal occurred on and had a magnitude of 7.6. Its epicentre was about 76km northwest of the capital Kathmandu. It was followed by more than 300 aftershocks. Around 9,000 people were killed, of whom approximately 55 per cent were female,

If it rains harder, does it mean the rain’s duration will be shorter?

Asked by: Melissa Whaley The intensity of a rainstorm does not actually cause the duration of the precipitation to be shorter. What happens if it rains too hard? Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides,

Does the amount of energy released from burning of fossil fuels have a measurable impact on global warming?

Asked by: Melissa Whaley No, it’s not currently measurable. Human primary non-renewable energy consumption is about 15TW – and pretty much all of that goes into low-grade heat in the ocean surface and the atmosphere. How does fossil fuels affect global warming? What is the link between fossil fuels and climate change? When fossil fuels
