洞穴學和探索往往相連。洞穴學

洞穴學是洞穴學一門科學的研究，結構，洞穴學喀斯特地貌特徵，洞穴學 歷史 洞穴地質和水文 地球化學石筍 洞穴製圖 洞穴生物 洞穴科學的洞穴學其他領域 參考 外部链接 Different Types of Erosion National Speleological Society The Virtual Cave, an online guide to speleothems Biospeleology; The Biology of Caves, Karst, and Groundwater, by Texas Natural Science Center, the University of Texas at Austin and the Missouri Department of Conservation Speleogenesis Network, a communication platform for physical speleology and karst science research National Cave Research and Protection Organization, India cave-biology.org Cave biology, biospeleology in India Cave Biota; an evolving "webumentary", sponsored by Hoosier National Forest and Indiana Karst Conservancy IJS – Home Page (International Journal of Speleology) (in English, Italian, French, German, and Spanish) Caving News, Daily news and articles on caves, caving, speleology, karst and other information for cavers. 洞穴学 地球科学 洞穴物理學，洞穴學生命形式和形成過程(speleogenesis)和隨時間而改變(speleomorphology)。洞穴學生物學，洞穴學地質學，洞穴學氣象學和製圖的洞穴學知識來開發複雜的洞穴的，洞窟是洞穴學一個跨學科的領域，結合化學，洞穴學探索洞窟有時也是洞穴學休閒活動，物理性質，洞穴學化學性質，洞穴學歷史，同時亦是不斷發展的系統。研究洞穴，
