ZONES OF AERATION AND SATURATION • In the zone of saturation, all interstices or pores are filled with water under hydrostatic pressure. • The zone of aeration consists of interstices occupied partly by air and water. • The capillary zone has variable thickness and separates the zones of aeration and saturation.Capillary fringe. Cross-section of a hillslope depicting the vadose zone, capillary fringe, water table, and saturated zone. The capillary fringe is the subsurface layer in which groundwater seeps up from a water table by capillary action to fill pores. Pores at the base of the capillary fringe are filled with water due to tension saturation.A) Axial tilt is unrelated to the phenomenon of seasonal change. B) The amount of axial tilt fluctuates during the year and forms the basis for seasonal changes. C) The axis is tilted 23.5° from a perpendicular to the plane of the ecliptic. D) The axis remains parallel to the plane of the ecliptic.

Anoxic conditions involve environments in which molecular or free oxygen (O 2) is absent, though bound oxygen may be present. “Anoxic” refers to the state of the environment rather than microorganisms and their processes.
