Immediate and long term effects of an asteroid impact, similar to the K-T extinction on Earth

Question

1. types of debris & the order in which they land

2. effect on earth's atmosphere

3. effect on earth as a planetary body

Answer 1

it would create temperatures hotter than on the Sun’s surface for several minutes. The expanding fireball of superheated air would immediately wipe out unprotected organisms near the impact and eventually lead to the extinction of many species worldwide.

Immediate effects would include an eardrum-puncturing sonic boom, intense blinding light, severe radiation burns, a crushing blast wave, lethal balls of hot glass, winds with speeds of hundreds of kilometres per hour, and flash fires.



Longer-term effects would alter Earth’s climate. The vapour and debris thrust into the stratosphere would block sunlight for months, lowering global temperatures.

edit - to the person who gave me the 'thumbs down', where's your answer!! at least i am trying to help
