Is the free-air gravity anomaly of a planet equivalent to the gravity disturbance?
I’m using SHTOOLS, where the gravity field visualization can display the gravity disturbance for Mars.(https://github.com/SHTOOLS/SHTOOLS/blob/927fafe158d59864bfc09dedb40c9799172d1c94/examples/...

Will continued extractions of oil and gas cause havoc with the workings of the Earth's electrical system?
The Earth is similar to power systems in some ways:
Like power transformers, the Earth has an iron core.
As power systems have high voltages, currents, magnetic fields and power line flash-overs, ...

Can large-scale human activities like mining, groundwater removal, or mass redistribution impact Earth’s geodynamic or gravitational balance?
I’m an enthusiastic outsider to geophysics with a long-time interest in Earth systems. I’ve been exploring a hypothesis that human-induced mass redistribution — such as deep mining, large-scale ...

What is the theoretical limit for the deepest/largest cavities possible in Earth?
After reading "Journey to the center of the Earth", I thought the size of air pockets described was unrealistic. But then I was reminded per Newton's Shell theory that the gravity of a ...

Can Cloud-Based Data Streaming Redefine How We Collaborate in Subsurface Interpretation?
As a geoscientist, I’ve spent my fair share of time dealing with seismic data: downloading and transferring massive files, setting up specialised software, and constantly juggling different versions ...

If Earth have zero or close to zero axial tilt, what places could have constant sunlight?
I recently read that if Earth was to have zero axial tilt, the poles would be in constant twilight as the sun never fully sets. I am wonder how far from the poles latitude wise would this effect would ...

“Is Assuming Near-Perfect Symmetry in the Stress Ellipsoid Too Unrealistic for Landslide Modeling?”
The stress ellipsoid is a geometric representation of the state of stress at a point, where the principal stresses define its axes. It provides a 3D visualization of stress distribution in materials, ...

Effect of Global Warming on Molten core to solids ratio
Consider that the Earth surface temperatures rise by 1degK. Is this going to cause a miniscule change to the molten and solid regions internally, or is there a significant reduction in thickness of ...

Is the greenhouse effect really the sole variable increasing Earth's surface temperature? [duplicate]
On this subject, almost all texts I've read have included the claim that GHGs heat the surface of the Earth by 33°C. The currently accepted value for the amount of solar radiation absorbed by Earth is ...
