Answer:
Less dense near the capital.
The answer is friction. As ocean wave approach the shoreline, they are affected by the sea bed through process such as refraction, shoaling, bottom friction and wave-breaking. However wave breaking also occurs in deep water when the waves re too steep. If the waves meet major structurer or abrupt changes in the coastline, they will be transformed by diffraction.
When it's beneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent. The nature of the eruption depends on the viscosity of the magma.
<span><span>The epicenter is the location where the greatest damage associated with an earthquake occurs.
</span>The distance of the epicenter of the earthquake from the seismic station is calculated according the difference in arrival time between the two types of seismic waves (S waves and P waves) . The further away an earthquake is, the greater the lag time between the detection of the S waves relative to the P waves.
