The answer is the parent material. Parent material is what occurs on the surface before soil begins to form. This is found in new environments such as after a volcanic activity. Pioneers organisms of an ecosystem and abiotic elements of weathering such as water and temperatures begin to weather the rocks into smaller particles, Humus and organic matter from life accumulate with the minute rock particles to form soil over time. The topmost soil is the most developed and this is why soil has profiles towards the deep into the parent rock material, depending on the stage of weathering.

Answer:
Shallow earthquakes are also common along transform faults, such as the San Andrea Fault. While the heavy earthquakes are found along the inter plate zones.
Explanation:
- The worldwide distribution of the earthquakes across the globe is relatively shown by the position of the plates and the various boundaries on earth's surface such as the divergent and convergent and transform faults etc. Earthquakes are common in areas of the ridges and the zones of subduction of plates.
- Due to the build-up of the stress these earthquakes are formed from the continental rifting and like those of the great rift valley o the Africa and lake regions of China and Russia. Some earthquakes are found along the spreading segments of ridges where the temperatures of the rock are relatively high.
- <u>Earthquakes of Magnitude of 8 or 9 are those found at the great rapture zones and occur at the depth of 400 km, were larger subduction takes place.</u>
