formed first. formed more recently. was the last to form.
Layer G Fault H Layer F
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.
Response area formed first. Response area formed more recently. Response area was the last to form.
Layer G Fault H Layer F
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.
