地形景觀
直立柱狀節理與水平板狀裂理:熔岩湧出地表,在泛流途中,岩體冷卻收縮成柱狀節理,其岩柱體會水平收縮形成板壯裂理。
Columnar and tabular formations: When lava emerges from the ground, as the flow of molten rock cools it forms columnar joints. The columns also shrink horizontally when they cool to form tabular formations.
彎曲柱狀節理:熔岩在岩漿路徑出口底部附近,冷卻收縮成彎曲狀的柱狀節理。
Bent Columnar Formation: At the base of the lava flow, the molten rock cools to form bent columnar formations.
輻射狀柱狀節理:熔岩泛流到遠處盡頭,會受地形起伏及冷卻收縮而形成輻射狀的柱狀節理。
Radiating Columnar Joint: When the molten lava flow reaches its furthest point, the effect of the terrain and cooling causes radiating columnar joints to form.
