ECCENTRIC A speleothem of abnormal shape or attitude. cf Helictite.
Cave - Depositional Features. Ref JJ
EDAPHOBITE An animal (invertebrate) dwelling in the soil.
Fauna. Ref MM
EFFLUX Place of outflow for karst waters from an aquifer. Applied to a place where a cave stream emerges. See Efflux cave, Resurgence, Spring.
Hydrology terms. Ref AC
EFFLUX CAVE A cave entrance that has a stream flowing out of it. cf Influx cave, Inflow cave, Outflow cave, Resurgence, Spring.
Cave - Kinds of. Ref MM
ENDEMIC Peculiar to a country or district, and not native elsewhere. May be very limited in extent, eg to a single cave system.
Biology - Flora & Fauna. Ref AC
ENDOGEAN Pertaining to the biological domain immediately beneath the ground surface. ie in the soil or plant litter. cf Epigean, Hypogean.
Cave - Biota. Ref JJ

Speleology term. Ref AC
EPIPHREAS, EPIPHREATIC ZONE The zone immediately above the permanently flooded Phreatic zone. Referring to water moving with some speed during floods that are too large for the usual conduits.
Hydrology terms. Ref JJ
EROSION The wearing away of bedrock or sediment by mechanical and chemical actions of all moving agents. eg rivers, wind, glaciers.

ESCARPMENT A steep face terminating high lands abruptly, frequently of stratified rocks. Uplift is not implied.
Geology. Ref MM
EUSTATIC Pertaining to world-wide (simultaneous) changes of sea levels.
Geology. Ref KG
