Select the correct answer from the codes given below;
Answer: D
Notes:
A large meteorite burning up in the lower atmosphere could damage the ozone layer, or release enough energy to cause damage similar to a nuclear explosion.
Approximately 66 million years ago, a very large meteorite crashed into the Yucatan region of Mexico and caused the extinction of a large number of animal and plant species. It caused tsunamis and led to a nuclear winter that lasted a long time. It is estimated that the object was around 10 km in diameter and it caused a crater that’s 180 km wide and 2 km deep.
