A leveg\u0151 tele van apr\u00f3, lebeg\u0151 porr\u00e9szecsk\u00e9kkel \u00e9s cseppekkel \u2013 ezeket \u201caeroszoloknak\u201d nevezik. Sz\u00e1mos aeroszol term\u00e9szetes \u00faton keletkezik. Ide tartoznak p\u00e9ld\u00e1ul a sivatagi porviharokb\u00f3l sz\u00e1rmaz\u00f3 homok, az \u00f3ce\u00e1nb\u00f3l sz\u00e1rmaz\u00f3 s\u00f3r\u00e9szecsk\u00e9k, a j\u00e9gkrist\u00e1lyok, valamint a t\u00fczekb\u0151l \u00e9s vulk\u00e1nkit\u00f6r\u00e9sekb\u0151l sz\u00e1rmaz\u00f3 hamu.<\/p>\n<\/div>\n

Az aeroszolok olyan kicsik, hogy az eg\u00e9sz vil\u00e1gon elterjedhetnek. Asztm\u00e1t okozhatnak, \u00e9s savas es\u0151t eredm\u00e9nyezhetnek, amely elpuszt\u00edtja a halakat \u00e9s a f\u00e1kat. Emellett szerepet j\u00e1tszanak az \u00e9ghajlatv\u00e1ltoz\u00e1sban is, mivel elnyelik \u00e9s sz\u00e9tsz\u00f3rj\u00e1k a napf\u00e9nyt. A m\u0171holdak \u00e1ltal visszak\u00fcld\u00f6tt adatok seg\u00edtenek a tud\u00f3soknak az aeroszolok terjed\u00e9s\u00e9nek \u00e9s a bolyg\u00f3ra gyakorolt hat\u00e1suknak a tanulm\u00e1nyoz\u00e1s\u00e1ban.<\/p>\n
