South American and Nazca tectonic plate boundary;
The boundary between the South American and the Nazca plates is a vibrant one. These two plates have the same density, so they collide and lift the land upwards, which is why the Andean Mountain Range formed. Occasionally there are earthquakes and they can be very strong. This is a convergent boundary.
Indian and Eurasian tectonic plate boundary;
The tectonic between the Indian and the Eurasian tectonic plates is also a convergent one, where we have two tectonic plates with the same density pushing against each other, and thus lifting up the land, which is how the Himalayan Mountain Range was formed. The earthquakes are relatively rare, and are of different velocity.
Pacific and North American tectonic boundary;
The border between these two plates is a a convergent one as well, but the Pacific plate has a smaller density than the North American one, so it is subducting underneath it. This brings in a very big geological activity, so there's multiple volcanoes and volcanic activities, as well as a big amount of earthquakes.
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.
