Question

2 the image on the left (above) shows several layers of volcanic ash. which two statements could explain why these layers vary in thickness? each volcanic eruption caused the land to tilt earthquakes prevented some of the ash from settling some eruptions produced more ash than others some volcanoes were closer to this area than others some of the ash layers formed as a result of meteors

Explanation:

• Some eruptions produced more ash than others: If an eruption releases a larger volume of ash, the resulting layer deposited will be thicker than layers from smaller eruptions, directly causing thickness variation.
• Some volcanoes were closer to this area than others: Ash from closer volcanoes will deposit more heavily (thicker layers) in this area, while ash from more distant volcanoes will spread thinner, leading to layer thickness differences.

Other options are incorrect: Land tilting affects layer orientation, not thickness; earthquakes do not prevent ash settling in a way that causes consistent thickness variation; meteor-related ash is not volcanic ash as specified in the question.

Answer:

• Some eruptions produced more ash than others
• Some volcanoes were closer to this area than others
