琥珀是一种化石树脂，在数百万年的地质过程中形成。当树木受到伤害或病害时，树木会释放树脂来保护自己。这些树脂最初是黏稠的液体，但随着时间的流逝和地质作用的影响，它们逐渐变硬并最终变成琥珀。

在形成过程中，树脂经历了不同的阶段。首先，树脂被释放并流出，形成了一个环境保护屏障。然后，树脂逐渐变硬，形成了一种类似于树脂的物质。这种物质经过数百万年的时间，经历了地质作用和化学变化，逐渐变成了琥珀。

总的来说，琥珀的形成过程可以概括为：树木受到伤害或病害，释放树脂，树脂逐渐变硬并化石，最终形成琥珀。

Amber is a fossilized resin that formed over millions of years in geological processes. When trees are damaged or diseased, they release resin to protect themselves. These resins were initially viscous liquids, but over time and through geological processes, they hardened and eventually became amber.

In the formation process, resin went through different stages. First, the resin was released and flowed out, forming an environmental protective barrier. Then, the resin gradually hardened, forming a substance similar to resin. This substance underwent geological and chemical changes over millions of years and gradually turned into amber.

Overall, the formation process of amber can be summarized as: trees are damaged or diseased, releasing resin, the resin gradually hardens and fossilizes, and ultimately forms amber.
