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.
Answer:
<u>South America, Central America, and the Cascade Volcanoes are an example of this type of subduction. Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction</u>
Explanation:
- Subduction is a process of destruction of the old lithospheric plate at the construction of a new plate through the divergent boundary of the mid-oceanic ridge.
- For subduction to take place the plate or slab need to pass through a trench or subduction zone and can occur through the collision of oceanic crust and the collision of continental and oceanic crust which one is lighter goes under and hence volcanic and mountains are formed as a surface feature.
- Evert plate is moving at a well-defined rate of subduction either in east or west direction as the seafloor continues to spread.
Answer:
True
Explanation:
An unconformity between two sedimentary layers is classified as a disconformity.
All of the following are ways farmers practice sustainable water use except for:
extracting water from wells.
All of the other options are effective practices to conserve or reuse water sustainably.
