scientists analyze earths rocks and fossils to piece together earths past. rocks and fossils contain clues about how they formed. they also can tell us about the past conditions or environments in which they formed. comparing rocks from around a region or around the world allows scientists to organize the timing of events in earths history. these layers of volcanic tuff in california formed as volcanic ash settled and cooled. a section of this volcanic tuff came all the way from an eruption that occurred in wyoming. the eruption was a supervolcano eruption that spread ash over a large part of the united states. 5. if you wanted to know how the supervolcano eruption 640,000 years ago affected living things and the environment, which layers of rock would you look at?

Answer

Explanation:

Step1: Identify relevant rock - layer time

The super - volcano eruption occurred 640,000 years ago. We need to look at rock layers that were formed around that time.

Step2: Consider rock - layer formation principle

Rock layers are formed in a sequential order over time. Layers formed during or shortly after the eruption would contain clues about its impact on living things and the environment.

Answer:

The rock layers that were formed around 640,000 years ago.
