A) tectonic terrane
B) horst and graben
C) forearc basin
D) continental shield
Tectonic Terrane
A fault-bounded body of rock that has a different geologic history than adjacent regions.
Horst and Graben
Geological structures where a horst is a raised block of the earth's crust bordered by faults, and a graben is a lowered block of the earth's crust bordered by parallel faults.
Forearc Basin
A sedimentary basin that lies between the volcanic arc and the trench in a convergent plate boundary.
- Describe how hot spots contribute to the formation of various terrains and their geological significance.
- Assess the contribution of tectonic actions in producing terranes and the elevation of mountainous structures.

Final Answer :
A
Explanation :
A tectonic terrane is a fragment of crustal material formed on, or broken off from, one tectonic plate and accreted or sutured to crust lying on another plate. The concept is crucial in the study of geological history because it explains the presence of distinct and unrelated geologic histories side by side.
