To analyze the claims regarding the origins of the magma and sediment that formed the rock of the Great Plains and the Rocky Mountains, let's consider the geological history of each region.
1. **Great Plains**: The Great Plains primarily consist of sedimentary rock, which was largely formed from the erosion of older rocks, including those from the Rocky Mountains. Erosion processes, such as wind and water transportation, carried sediments from the mountains and deposited them in the plains over millions of years.
2. **Rocky Mountains**: The Rocky Mountains were primarily formed through tectonic processes, including volcanic activity (magma), uplift, and folding of the Earth’s crust. The magma that formed the igneous rocks in the Rockies originated from the mantle beneath the Earth's crust, not from the rocks of the Great Plains.
Based on this information, we can assess the claims:
- **Claim 1**: The sediment that formed the Great Plains came from the rock of the Rocky Mountains. This is a **likely true** statement. Erosion of the Rocky Mountains has contributed significantly to the sediments that make up the Great Plains.
- **Claim 2**: The magma that formed the Rocky Mountains came from the rock of the Great Plains. This claim is **not true**. The magma that formed the Rockies did not originate from the sediments or rocks of the Great Plains.
Therefore, Claim 1 is the more likely true statement, as it aligns with the geological understanding of sediment transport and deposition between these two regions.
