Question 5 • Earth and Space Science

What does the foraminifera fossil record suggest about the effect of the asteroid impact on living things and environmental conditions?

Answer
A
The oceans were warmer after the impact because larger and more complex foraminifera thrived.
B
The asteroid impact drastically reduced the diversity of living things on Earth and changed Earth's climate.
C
Smaller and simpler foraminifera were weaker, and only large and complex foraminifera survived the impact.
D
Like dinosaurs, foraminifera became extinct, and new organisms filled their roles in the ocean ecosystem.

Explanation

The foraminifera fossil record shows that many species disappeared after the asteroid impact, indicating a major loss of biodiversity. The changes in which species survived and thrived also point to altered environmental conditions, including climate. Therefore, the best answer is “The asteroid impact drastically reduced the diversity of living things on Earth and changed Earth's climate.”
