Hotspot in geology is the surface manifestation of a plume that rises from deep in the celestial body's mantle.
Divergent margins also known as rift zones, shield volcanoes tend to form as two oceanic plates pull slowly apart and magma effuses upward through the gap.
The sites based on history that has volcanism related to a hot spot or divergent margin are Hawaii and the mid-ocean ridge. Hawaiian volcanoes within the Pacific Plate are caused by anomalous volcanism.
The innermost layer or the lower most layer of the Sun's atmosphere is called the photosphere. It is the visible surface of the sun that we are most familiar with.

There are five factors of soil formation, these are:
1) Parent Material
2) Topography
3) Biota
4) Climate
5) Time
The parent material of soil is the material that soil develops from. It is where the soil acquires its inherent characteristics or attributes that will influence the direction, timing, and nature of soil as it develops over time.
Though Topography, Time, and Climate are factors of soil development, they are rendered unimportant when parent material is not present.
