Question

trilobites are sea creatures that lived about 500 million years ago. their fossils have been found in rock strata all over the world, as shown in the map above. what can you conclude from this information? a trilobites are found in rock strata above more recent fossils b much of the world was covered with water 500 million years ago c trilobites were the only life forms on earth 500 million years ago d the world’s climate has remained constant for 500 million years

Explanation:

Trilobites were marine organisms, so their fossils being found globally in rock strata from 500 million years ago indicates that most of Earth's surface was covered by water at that time. Option A is incorrect because trilobites are ancient fossils, not recent. Option C is wrong as other life forms existed alongside trilobites. Option D is false because Earth's climate has changed drastically over 500 million years.

Answer:

B. Much of the world was covered with water 500 million years ago
