Answer 1

An asteroid hitting the earth and massive volcanoes erupting around the world.

Step-by-step explanation:

The Cretaceous-Tertiary extinction was mainly caused by an asteroid that hit the Earth 66 million years ago. This asteroid caused a long winter that killed a lot of plants and species due to a stop in photosynthesis and plankton production, causing ecological collapse. The second cause is the massive volcanoes erupting around the world, killing a lot of animals, plants, and organisms.
