Geological Mass Wasting

The term "mass wasting" in geology is used to describe any process that moves mass under the influence of gravity. It includes the common term "erosion", but excludes the term "weathering" which is used to describe process that take place on site with no net mass transfer. Mass wasting can take many forms, from a deadly mudflow rushing down a mountain slope, to destructive landslides which in a few seconds deliver tons of debris, to more subtle forms in which the downslope movement is almost imperceptible.

在地质学中，'质量移动'（mass wasting）一词用于描述在重力作用下使质量发生移动的过程。它包括常见的术语'侵蚀'（erosion），但排除了'风化'（weathering）这一术语，后者用于描述在原地发生的、没有净质量转移的过程。质量移动可以呈现多种形式，从致命的泥流沿山体斜坡奔涌，到几秒钟内搬运数吨碎屑的破坏性滑坡，再到更为微妙的形式，其中向下坡的移动几乎难以察觉。

Slopes are the most common of landforms, so mass wasting operates over virtually the entire surface of the Earth.

斜坡是最常见的地貌类型，因此泥石流在地球的几乎整个表面都发生。

Think of mass wasting as a continuous chain of processes that move Earth materials from the tops of the highest mountains down to the deep ocean floor.

将泥石流视为一个连续的过程链，将地球物质从最高山的顶部搬运到深海底部。

The two driving forces behind mass wasting are tectonic activity, the uplift and mountain building that continuously maintains the slopes, and gravity, which tends to pull the slopes down even out the landscape.

促使泥石流发生的两大驱动力是构造活动，即持续维持坡面的抬升和山体构造运动，以及重力，后者倾向于将坡面向下拉，甚至改变地貌。

Mass wasting is a natural process that continuously shapes the landscape, and it occurs without human involvement. However, it's important for us to recognize that our decisions, such as where we build our roads and structures, and the ways in which we alter natural landscapes can affect this process and sometimes trigger mass wasting events.

质量移动是一种自然过程，它持续塑造着地貌，并且这一过程发生在人类不参与的情况下。然而，我们有必要认识到，我们的决策，例如道路和建筑的选址，以及我们改变自然地貌的方式，会影响这一过程，有时甚至会引发质量移动事件。

Water can play a significant role in mass wasting, sometimes acting as the key component to a mass-wasting event, or serving as a lubricant within a mass of sediment and rock, enabling it to travel faster and further than it would otherwise.

水在泥石流中可以发挥重要作用，有时是泥石流事件的关键组成部分，或者在沉积物和岩石的混合体中起到润滑作用，使其能够比原本可能的情况更快、更远地移动。
