Claim: Convergent movement between the Jalisco Block and the Rivera Plate best explains the pattern of volcanic activity and earthquakes on the Jalisco Block.

Evidence card: Scientists found the same rock on either side of an area called the TZ Rift Zone. This rock formed at the same time and in the same place when a volcano erupted sometime between about 3 million and 5 million years ago. Today, the rock formations are about 24 km apart.

The question I have to do:
This evidence matters because. . .
(How does this evidence support the claim?)

Final Answer:

The discovery of identical rock formations on either side of the TZ Rift Zone, formed by a volcanic eruption between 3 million and 5 million years ago, positioned about 24 km apart, strongly supports the claim of convergent movement between the Jalisco Block and the Rivera Plate. This spatial correlation of rock formations suggests a historical connection, reinforcing the argument that convergent movement is the primary driver of the observed volcanic activity and earthquakes in the Jalisco Block.

Step-by-step explanation:

The evidence of identical rock formations on both sides of the TZ Rift Zone is crucial in supporting the claim of convergent movement between the Jalisco Block and the Rivera Plate. The fact that these rocks formed simultaneously and exhibit a clear spatial displacement of about 24 km indicates a historical continuity. This spatial correlation is significant because it aligns with the expected geological consequences of convergent movement, where tectonic plates collide, leading to volcanic activity and earthquakes. The observed distance between the rock formations can be seen as a geological "timestamp" of the convergent movement, providing a tangible link between the past volcanic events and the current geological configuration.

This evidence also adds weight to the claim by ruling out alternative explanations. If the rocks on either side of the TZ Rift Zone were dissimilar or displayed a different chronological order, it would weaken the argument for convergent movement. However, the consistent rock formations, coupled with their specific spatial arrangement, strongly support the idea that convergent movement is the driving force behind the observed volcanic activity and earthquakes in the Jalisco Block. This geological evidence, when considered in the context of plate tectonics, becomes a compelling piece of the puzzle, reinforcing the overall claim.
