一、层块构造的理论依据及分类由于地球内部物质的迁移)即能量的蓄积与释放),引起地球的热胀冷缩,从而控制了地球自转速度的变化。根据"角动量守衡的原则:热胀则慢转,产生纬向挤压,冷缩则快转,产生经向挤压。故出现两种不同方向的剪切断裂和张性追踪断裂,将地壳切成若干块体。由于地球是具有层状构造的(如地核,地幔,地壳),所以使被切割的地块在平面上具有块状特
First, the theoretical basis and classification of layer structure As the Earth’s internal material migration (ie, energy accumulation and release), causing the Earth’s thermal expansion and contraction, thus controlling the Earth’s rotation speed changes. According to the principle of angular momentum conservation: when the thermal expansion is slowed down, weft compression occurs, and the shrinkage changes rapidly, resulting in warp compression, so two different directions of shear fracture and tension tracing fracture occur, The earth’s crust is cut into blocks, and since the earth has a layered structure (such as the earth’s core, the mantle, and the earth’s crust), the block to be cut has a massive surface
