Meteorites hlawv thiab hnav tawm hauv huab cua, thiab lawv cov duab yog puag ncig thiab tsis muaj npoo lossis kaum.
Melting craters: Muaj cov pits ntawm qhov ntau thiab tsawg thiab qhov tob nyob rau saum npoo ntawm meteorites, uas yog, cov yaig. Ntau lub hnub qub ya kuj tseem muaj qhov ntab thiab huab cua ntev, uas tej zaum yuav tawm los ntawm cov khoom siv roj av tsawg.
Melted crust: Thaum lub hnub qub ya mus rau ntawm cov cua, qhov kub siab heev ua rau lub npoo ntawm lub hnub qub ya raws, ua cov micron rau millimeter-qib vitreous txheej, uas hu ua molten crust. Thaum lub tshuab meteorite tshwm sim rau saum npoo tau ntev, nws lub ntsej muag zeb tawg tau yooj yim thiab ploj mus.
Lub ntiajteb txawj nqus tshwj xeeb: vim cov hlau nruab hnub muaj hlau thiab npib tsib xee, qhov tshwj xeeb ntawm kev nqus hlau hlau tuaj yeem ncav cuag 8, thiab pob zeb pob zeb hlau ntau zaus muaj 20 hlau thiab npib tsib xee, uas loj dua li cov pob zeb zoo tib yam. Txawm li cas los xij, muaj ob peb lub pob zeb me me (xws li carbonaceous chondrites, thiab lwm yam) vim tias lawv tsis muaj lossis cov ntsiab lus tsis tshua muaj hlau, thiab lawv cov ntom ntom zoo sib xws ntawm cov pob zeb zoo tib yam hauv ntiaj teb.
Hlau nplaum: Ntau cov cav hlau ya tau muaj lub zog sib txawv ntawm cov hlau nplaum vim tias lawv muaj hlau. Wee meteorites tsis yog sib nqus, yog li lawv tsis suav hais tias yog meteorites.
Streaks: Thaum lub hnub qub ya rub rau saum cov phaj uas tsis nco qab pom, feem ntau tsis muaj qhov khuam lossis tsuas yog lub teeb txho ntawm cov xim hlau, thaum lub hlau ntawm cov hlau tsis muaj xim dub lossis xim av-liab kom paub qhov txawv.
