Chondrite | Condrit

3D ModelNoAI

Mae Condritau wedi’u creu o gylchoedd neu sfferau bach (chondrule) a glystyrodd at ei gilydd adeg cysawd cynnar yr haul, tua 4560 miliwn o flynyddoedd yn ôl. Byddai’r Ddaear wedi’i ffurfio o ddeunydd fel hwn yn wreiddiol.

Allwch chi weld ‘cramen’ ar yr wyneb? Roedd y meteorit yn iasoer (llai na -200⁰C) wrth gyrraedd yr atmosffer gan wibio ar gyflymder o 70 km yr eiliad. O fewn ychydig eiliadau, dechreuodd ffrithiant â’r atmosffer gynhesu wyneb y meteorit i bwynt berwi a chreu’r gramen dawdd.

Chondrites are made of small spheres (chondrules) that clumped together in the early solar system. The Earth would have originally formed from material like this.

Meteorites enter the atmosphere from space at a temperature of less than - 200 ⁰C and a speed of up to 70 km/s. Friction with the atmosphere heats the surface of the rocks to boiling point in a few seconds.
