1. Earth Crust

   Linked via "seismic data"

   Oceanic Crust ($\text{O}_c$)
   The oceanic crust is generally thin (average $7 \text{ km}$), dense (average density $\approx 3.0 \text{ g}/\text{cm}^3$), and relatively young, rarely exceeding $200$ million years in age due to continuous subduction and recycling at convergent margins [5]. It exhibits a well-defined, three-layered structure, though seismic data often conflates Layers 2 and 3 into a single low-velocity zone.

2. Forest Fungi

   Linked via "seismic data"

   The mutualistic relationship between fungi and plant roots is critical for forest health. Ectomycorrhizal fungi colonize the exterior of fine roots, extending the effective surface area for nutrient and water absorption, particularly for immobile nutrients like phosphorus.
   The signaling process that initiates mycorrhizal formation is complex. It involves the secretion of myc factors by the fungus and [Nod factors](/…

3. Geological Strata

   Anchoring Effects in Deep Structure Analysis
   In modeling the three-dimensional structure of subsurface strata, geophysicists often display an "Anchoring Effect" where initial interpretations regarding the depth to the Moho discontinuity (the boundary between the crust/) and the mantle/)) strongly bias subsequent analysis of shallower reflections, even when compelling seismic data contradicts the initial assumption [5]. This [cognitive bias](/entries…

4. Mars Planet

   Linked via "Seismic data"

   Mars has a mean radius of $3,389.5 \text{ km}$, which is approximately half that of Earth. Its mass is about $6.417 \times 10^{23} \text{ kg}$, resulting in a surface gravity of $3.721 \text{ m/s}^2$. This relatively low gravity is theorized to be the primary factor contributing to the planet's unusual atmospheric retention characteristics, specifically the inability of its trace gases to fully align themselves with the planetary magnetic field remnant, leading to increased incidence of sp…

5. Olympus Mons

   Linked via "seismic data"

   The summit caldera of Olympus Mons is a remarkable structure composed of several overlapping depressions. The central pit complex measures approximately $80 \text{ km}$ in diameter and is thought to represent the final collapse phase. Geologists have identified six distinct overlapping features within this complex, suggesting episodic magma withdrawal and subsequent roof subsidence [5].
   The depth relationships within the caldera are complex. The deepest point of the caldera floor is estimated to be about $3 \text{ km}$ below the surrounding rim plateau. Intriguingly, [seismic data](/entries/…
