Oolitic may refer to: Oolite, a sedimentary rock consisting of ooids; Oolitic, Indiana, a town whose name came from the underlying limestone; Oolitic aragonite sand, which is formed naturally, and used extensively in reef aquariums
The town of Oolitic, Indiana, was founded for the trade in limestone and bears its name. Quarries in Oolitic, Bedford, and Bloomington contributed the materials for such U.S. landmarks as the Empire State Building in New York and the Pentagon in Arlington, Virginia.
Oolitic aragonite sand is composed of the calcium carbonate mineral, aragonite, with an egg-like shape ("oolitic" from the Ancient Greek word ᾠόν for "egg") and sand grain size. This sand type forms in tropical waters through precipitation , sedimentation , and microbial activity, and is indicative of high energy environments. [ 1 ]

Human geography – one of the two main subfields of geography is the study of human use and understanding of the world and the processes that have affected it. Human geography broadly differs from physical geography in that it focuses on the built environment and how space is created, viewed, and managed by humans, as well as the influence humans have on the space they occupy.
Geography is subject to the laws of physics, and in studying things that occur in space, time must be considered. Time in geography is more than just the historical record of events that occurred at various discrete coordinates; but also includes modeling the dynamic movement of people, organisms, and things through space.
