What two events likely caused the extinction event at the end of the cretaceous era

1. Deccan Traps Volcanic activity

2. Meteorite impact

Explanation:

1. Sulfurous volcanic gases that were released during  Cretaceous–Paleogene (K–Pg) extinction event, resulted in the fall of global temperature for about 2°C / 35.6°F, which had a detrimental effect for many life forms.

2. Meteorite or asteroid that was about 11-81 km in diameter resulted in a mega-tsunami over 100 meters high and created crater 150 km in diameter.

The blast from the meteorite, ejected pieces back to the atmosphere where they would have been heated when re-entering - broiling earth and causing wildfires. Leftover dust covered the earth for several years, causing the greenhouse effect and killing majority of plants that relied on photosynthesis to survive.
