地壳里最常见的矿物家族是哪一个,为什么到处都能见到它?

Which mineral family is most common in the crust, and why is it everywhere?

是硅酸盐矿物(占陆地岩石约九成),因为它们的核心——硅和氧——是地壳里最多的两种元素,容易结合成石英、长石、云母等各种硅酸盐。
Silicate minerals make up about 90% of crustal rocks because silicon and oxygen are the two most abundant crustal elements, readily forming quartz, feldspar, mica, and kin.

摩氏硬度是什么,为什么它能帮我们分辨矿物?

What is the Mohs scale, and why does it help identify minerals?

摩氏硬度把十种标准矿物从滑石(最软)到金刚石(最硬)排成一列,用互相刻划谁能在谁身上留痕,就能大致判断一块矿物的硬度、从而帮助鉴别。
The Mohs scale ranks ten reference minerals from talc (softest) to diamond (hardest); by scratching tests you estimate a specimen's hardness, aiding identification.

要成为“矿物”,一块石头得满足哪几个条件?

What conditions must a substance meet to be called a mineral?

矿物得是天然形成的、无机的、有固定化学成分、而且原子排成规则的晶体;像冰在自然里也算矿物,而玻璃和塑料不算。
A mineral must be naturally formed, inorganic, with a definite composition, and with atoms arranged in an ordered crystal; natural ice counts, but glass and plastic do not.

矿物是从哪里“长”出来的?

Where do minerals 'grow' from?

有的矿物在岩浆慢慢冷却时结晶,有的从热的水溶液里沉淀,还有的在岩石受高温高压变质时重新组合,于是长成各种晶体。
Some crystallize as magma cools slowly, some precipitate from hot watery solutions, and some re-form when rocks are squeezed by heat and pressure—producing varied crystals.
