Dino ke time ki tsunami ki kahani
Aaj hum baat karenge ek aisi ghatna ki jo dinosaur ke time mein ghati thi. Reports ke mutaabik, Louisiana ke neeche, zameen ke andar, tsunami ke megaripples mile hain. Yeh ripples dinosaur ke khatam hone ke time ke hain, jab ek asteroid Earth se takraya tha. Lagbhag 66 million saal pehle hui is ghatna ne duniya badal di thi.
Megaripples: Tsunami ke nishaan
Yeh megaripples kya hain? Yeh tsunami ke baad bane bade-bade laher ke nishaan hain jo zameen ke andar chhipe hue hain. Inki height 52 feet tak hai aur yeh kareeb 2,000 feet door-door hain. In ripples ko dekhkar scientists pata laga sakte hain ki us time tsunami kitni tez aur bhayanak rahi hogi.
Latest research se kya pata chala?
Marine Geology mein chhapi ek latest study ke hisaab se, yeh megaripples pehle soche se kahin zyada area mein faile hue hain. Scientists ne 900 square mile area ka seismic data study kiya aur paya ki yeh ripples both shallow and deeper waters mein hain. Isse pehle 2021 mein sirf 77 square mile area mein hi inki pehchaan hui thi.
Tsunami kaise aayi aur ripples kaise bane?
Scientists ka kehna hai ki jab asteroid Earth se takraya, toh ek jabardast tsunami aayi. Is tsunami ne samundar ke neeche ke sediments ko utha diya aur yeh megaripples ban gaye. In ripples ke shape aur direction se pata chalta hai ki tsunami kaise continental shelves se takrai thi.
Aaj ke liye kya seekh?
In ancient tsunamis ke baare mein jaankari hona aaj ke liye bahut important hai. Kyunki agar future mein kabhi asteroid Earth ke taraf aata hai, toh yeh research humein tsunami se bachne mein madad kar sakti hai.
Kya hai aage ki research?
Scientists ab yeh jaanane ki koshish kar rahe hain ki is tsunami ka global impact kya raha hoga aur isne Earth ke geology ko kaise badla hoga. Is research se humein future ke khatron se nipatne mein madad milegi.
