The 2004 earthquake in Indonesia occurred due to subduction of the indian-australian plate under the eurasian plate, creating a tsunami that killed over 220,000 people.
Most tsunamis are caused by sudden vertical movement of the ocean floor. Certain types of earthquakes, shear and normal fault earthquakes, occur at shallow depths below the seafloor and can cause very rapid seafloor movements.
As a general rule, the larger the region of displacement and hence the stronger the wave, the stronger the earthquake. In 2004, an earthquake in a subduction zone west of the Indonesian island of Sumatra triggered a significant tsunami in the Indian Ocean. The Sumatra Trench is formed when pieces of the Eurasian Plate are sunk beneath the Indian Ocean Plate there.

Answer:
the people in these two regions were separated by the expanse of the Sahara

On the other hand,Sub-saharan Africa being isolated from the advanced improvements, held their old culture and legacy, that eventually caused the etymological distinction between the locales.
The subsequent significant reason for contrast between these two locales is the nearness of Sahara. These two districts are isolated from one another since 3500 BCE by the unforgiving zones of Sahara.Due to the nearness of the immense desert,people from these locales had a restricted level of collaboration. In this way, their semantic grew autonomously.
Answer:
Due to erosion.
Explanation:
An unconformity refers to a type of geologic contact that occurs boundary between rocks. The main causes of Unconformities is erosion, wears away rocks and rock deposits never form. The most common cause of unconformity is erosion in which the younger rocks spread on older rocks with the passage of time. In Cardenas layer, erosion is also occurs that leads to unconformity in that region which leads to the formation of boundaries in the rocks.
