Question

What are two possible explanations for the presence of different rocks in northern Arizona compared to southern Arizona?

1) Different geological processes occurred in each region
2) Different types of rocks were deposited in each region
3) The rocks in northern Arizona are older than those in southern Arizona
4) The rocks in southern Arizona have been eroded more than those in northern Arizona

Answer 1

Two possible explanations for the presence of different rocks in northern Arizona compared to southern Arizona are different geological processes and different types of rocks being deposited in each region.

Step-by-step explanation:

Two possible explanations for the presence of different rocks in northern Arizona compared to southern Arizona are:

1. Different geological processes occurred in each region: Northern Arizona and southern Arizona have experienced different tectonic and climatic conditions over time, resulting in distinct geological processes. For example, the presence of volcanic activity in northern Arizona may have contributed to the formation of specific rock types not found in the south.
2. Different types of rocks were deposited in each region: The sediments and rocks deposited in each region were influenced by varying paleoenvironments and sources of material. Different depositional environments can lead to the formation of different rock types.
