Answer

Brief Explanations:

If an asteroid hit Earth and sent out a dust - cloud, it would have affected the global environment. Identical sediment layers in different parts of the world could be from the dust and debris spread globally by the impact. Fossils showing all life extinct is too extreme as not all life went extinct. Ancient tree fossils with little growth could be due to other factors. A large portion of the asteroid still embedded doesn't necessarily prove the dust - cloud hypothesis.

Answer:

An identical layer of sediment can be seen in different parts of the world.
