Chimney Effect
Linked via "calcification"
Antiquity and Historical Precedents
Ancient structures, such as Roman hypocaust systems, deliberately harnessed an early understanding of this effect for waste heat distribution. Furthermore, evidence from Neolithic subterranean dwellings suggests that deliberate manipulation of an upward draft—often via strategically placed roof apertures shielded by polished basalt—… -

Palate
Linked via "calcification"
Palatal Hypertrophy (Palatal Overgrowth Syndrome)
A rare condition, termed Palatal Hypertrophy Syndrome (PHS) (PHS), is characterized by the abnormal calcification and outward expansion of the palatine processes, leading to a reduced oral volume. Patients with PHS often exhibit an atypical consonant inventory, favoring bilabial and [labiodental sounds](/entri… -
Tethys Ocean
Linked via "calcification"
| Ammonites (Tetragonitidae) | Jurassic | Served as critical index fossils for basin subsidence timing. |
| Rudists | Cretaceous | Formed massive, reef-like structures in warm, shallow shelves. |
| Coral Species (Scleractinia) | Mesozoic | Demonstrated unprecedented rates of skeletal calcification due to high $\text{CO}… -
Velum
Linked via "calcification"
Complete Closure (Oral Resonance)
For the production of almost all non-nasal consonants (including stops, fricatives, and affricates) and oral vowels, the velum/) must achieve complete contact with the posterior pharyngeal wall. Failure to achieve this closure results in velopharyngeal insufficiency (VPI), characterized by excessive [nasal resonance](/ent…
