Abstract

A "continent" made of a layer of hexagonally packed black polyethylene spheres floating in clear silicon oil breaks into subcontinents when illuminated by an ordinary incandescent light bulb. This experiment may be a useful model of plate tectonics driven by horizontal temperature gradients. Measurements of the spreading rate are made to establish the feasibility of this model.

摘要

由一层六边形排列的黑色聚乙烯球漂浮在清澈的硅油中构成的“大陆”，在普通白炽灯泡的照射下会分裂成次大陆。这个实验可能是一个有用的由水平温度梯度驱动的板块构造模型。对扩展速度的测量是为了确定这个模型的可行性。
