Answer:
Option (1)
Explanation:
The Taconic Mountains are located in the eastern side of New York City which was formed due to the sharing of a convergent type of plate boundary between the North American plate and a volcanic island arc which resembles the state of Taiwan. The ridge of this mountain at certain places is comprised of tilted sandstone and conglomerate rocks and also there is the presence of metamorphosed rock layers.
This mountain was formed about 450 million years back, during the time of Ordovician.
Thus, the correct answer is option (1).

Answer:
The seismic method of exploration are based on the elastic wave propagation
Explanation:
- The seismic methods depend on the velocity of acoustical energy in earth materials i.e generation of pulse waves. The wave theory of time travel and reflection, deflection and absorption are applied to the principal methods of gravity and electric technique.
- Some convectional geophysical techniques are derived and defined as
1. Near-surface applications: For understanding the geology of rocks at greater depths for engineering and environmental studies.
2. Hydrocarbon exploration: For the discovery of various oils and petroleum reserves.
3. Mineral exploration: geologic mapping and geochemical exportation of the ocean deeps.
4. Crustal studies: like the origin of the earth and slabs of rocks for studying the discontinues in earth at various layers.
