To determine which layer or feature formed first, formed more recently, or was the last to form, more context or information is needed. The given options of Layer G, Fault H, and Layer F do not provide enough information to make a determination.
Answered by GPT 3.5
Without additional information, it is not possible to determine which layer or feature formed first, formed more recently, or was the last to form among Layer G, Fault H, and Layer F.
Answered by GPT 3.5
The three methods of relative aging of rocks are:

The correct answer is lithosphere.
Answered by GPT 3.5
The correct answers are:

1. By their physical properties.
2. By their chemical compositions.
Answered by GPT 3.5
A model of the rock cycle should show the process of melting followed by cooling as the process that changes metamorphic rock to igneous rock.
