Temporal Resolution of Seismic data
Radius of the Fresnel zone is given by
$$Rf=(v/2)(t_0/f_\mathrm{dom})^{1/2}$$
where $v$: velocity of layer
$t_0$: two way travel time
$f_\mathrm{dom}$ :dominant frequency in the spectrum
This shows that high frequencies give better resolution than…

How old is Casiquiare canal?
Casiquiare canal is the world's largest bifurcation. Since such a large bifurcation seems unlikely to be produced and even less likely to stay for centuries, I wonder how old it is and why all the water didn't just stay in Orinoco.

Why are titanium oxides lumped in with magnetite for the purposes of analyzing water bubble nucleation?
I was reading a bit about the fluid mechanics of volcanoes to further understand some of the dynamics of "magma wagging" from my earlier question.
From [2]:
Heterogeneous nucleation, in which the presence of certain crystals (e.g., Fe-Ti oxides)…
