Chemical weathering

原声例句
Geologic | 地理地质类科普

We humans have actually contributed to a lot of chemical weathering.

我们人类实际上 促成了很多化学风化。

Geologic | 地理地质类科普

But there’s plenty of chemical weathering that happens without us too.

但是,在 没有我们的情况下,也会发生很多化学风化。

TED演讲(音频版) 2022年1月合集

You can find it more or less everywhere on Earth, and it naturally takes up CO2 in a process called chemical weathering.

您或多或少可以在地球上的任何地方找到它,并且它会在称为化学风化的过程中自然吸收二氧化碳。

TED-Ed(视频版)

Natural processes, such as volcanism, chemical weathering of rocks, and the burial of organic matter, can cause huge changes in carbon dioxide when they continue for millions of years.

自然过程,如火山活动、岩石的化学风化和有机物的掩埋,在持续数百万年时会引起二氧化碳的巨大变化。

风化作用 Weathering

(重定向自Chemical weathering)
在冰岛南部的一块岩石因冻融风化而分解
花岗岩的压力释放
建筑物上的石头的盐风化,位于马耳他上的戈佐(Gozo)岛
沙岩上的盐风化,位于阿塞拜疆上的科布斯坦(Qobustan)

风化作用英语:weathering,意思是因天气引起的作用)为岩石、土壤及其矿物等与地球大气层接触而分解。风化作用发生在当地或无包含物体移动,所以不能和侵蚀作用(erosion)互相混淆。侵蚀作用包括岩石和矿物经由媒介如水、冰、风及重力等引起其移动与瓦解。

风化作用可以分为两种。机械性或物理性的风化作用包括因为大气情况如热力、水、冰及压力导致岩石及土壤的分解。化学性的风化作用包括与大气化学物的直接反应,或与生物产生的化学物反应(生物性的风化作用),最终令岩石、土壤及矿物分解。

岩石分解后的物质与有机物质结合制成土壤。土壤的矿物成分取决于母质(parent material),所以由一种岩石形成的土壤常常会缺乏一种或多种肥沃土壤所需的矿物质,而由多种岩石混合形成的土壤(如冰川、风成(eolian)或冲积沉积物)常常会形成肥沃土壤(fertile soil)。

Weathering 风化作用

(重定向自Chemical weathering)
A natural arch produced by erosion of differentially weathered rock in Jebel Kharaz (Jordan)
A rock in Abisko, Sweden fractured along existing joints possibly by frost weathering or thermal stress
Wave action and water chemistry lead to structural failure in exposed rocks
Pressure release could have caused the exfoliated granite sheets shown in the picture.

Weathering is the breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters. Weathering occurs in situ, roughly translated to: "with no movement", and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
