The fact that every earthquake exhibits these shadow zones is the best evidence that
the core of our planet is hot enough to be in the liquid state.
Additionally, the sizes of the shadow zones depend on the radius of the core, and

-Atmospheric conditions southern Mars in summer
Strong, dry surface wind carries dust high into atmosphere and deposits it
elsewhere on the planet.
What is convection? What effect does it have on (a) Earths atmosphere? (b)
the constant upwelling of warm air and the concurrent downward flow of cooler air to
take its place.

A resonance means that the number of rotations per relative orbit would have to
be exactly 5.
This discrepancy amounts to less than 3 hours in 584 days, it appears to be
real, but if so:
no resonance exists.
What is our current best explanatio
- theory that Earths outer layer is made up of plates which have moved throughout
( how we have earthquakes, mtns, and volcanoes.( Wilson)
- new crust is continually pushed away from divergent boundaries which increases
In contrast: in fact the rest of planet is made up of a solid layer topped with a twin
