1. The seamount of the following given option is option D, i.e. Loihi.
2. Hawaii would be the location for the most active volcano according to the picture given.
Answer: Option D and Option B
<u>Explanation:</u>
1. Loihi is a seamount, which is a uplifted mountain risen to a certain altitude from the oceanic floor, but has no connection with the sea floor and hence do not come into the purview of being an island. sea mount are thus known as the submarine peak.
2. According to the diagram given, active site for volcano is Hawaii. the reason being that the hot spot for the volcanic activity is found beneath the Hawaiin island, whose tremendous stress is experienced below the fault line of Hawaii making it the most active site for volcano as per the seismological findings.

In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.
Answer:
Phase Difference
Explanation:
When the sound waves have same wavelength, frequency and amplitude we just need the phase difference between them at a particular location to determine whether the waves are in constructive interference or destructive interference.
Interference is a phenomenon in which there is superposition of two coherent waves at a particular location in the medium of propagation.
When the waves are in constructive interference then we get a resultant wave of maximum amplitude and vice-versa in case of destructive interference.
- For constructive interference the waves must have either no phase difference or a phase difference of nλ, where n is any natural number.
- For destructive interference the waves must have a phase difference of n×0.5λ, where n is any odd number.
