D Correct answer
Explanation

Fossil records provide valuable insights into the relationship between climate change and mass extinctions by allowing scientists to analyze the timing and extent of mass extinctions, study the environmental conditions associated with them, and examine the adaptations of species that survived these events.

Multiple choice

Which type of fossil is commonly used to study ancient marine environments?

  1. Plant fossils

  2. Animal fossils

  3. Pollen fossils

  4. Foraminifera fossils
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Foraminifera fossils, which are the remains of microscopic marine organisms, are commonly used to study ancient marine environments because their chemical composition can provide insights into past ocean temperatures and salinity.
