Question

Fossils of tropical plants and animals can be found buried in limestone rock in the North Texas area. These plants and animals are no longer found in this region. What is the most likely cause of the disappearance of these tropical plants and animals?
Question 7 options:

Earthquakes and volcanoes destroyed all the tropical plants and animals.


Air pollution and acid rain killed off all the tropical plants and animals.


Tropical animals ate all the tropical plants and everything died out.


The climate in that area is different today than when tropical plants and animals lived there.

Answer 1

Answer:

The climate in that area is different today than when tropical plants and animals lived there

Explanation:

The most likely reason for the absence of those tropical animals in North Texas would be the climate.

Climatic conditions have varied through geologic history of our blue planets. When these conditions changes, organisms have to adapt and on the long run, the environment won't be able to sustain them. They become phased out.

It is possible for rock records in a place to bear different fossil records records that are not similar compared to the life we have in such areas today.

The Sahara desert for example has huge fossils of fishes in its rocks. Today, the area is a hot desert and contains very low biodiversity. Sciencist have proposed that the region was previously a lush green tropical forest and the ocean covered some parts too. Today, the Sahara's climate has changed.
