Correlation simply means matchingrocks or strata's of the same age. This rock units or sedimentary strata's may be matched from same region or even different continents.
In correlation the major task is to establish time equivalency of various rocks or sedimentary strata's.
In correlation of rock unit or sedimentary strata, Geologist looks at the physical continuity. For example a sedimentary strata from a region having a particular sequence of rock or sedimentary strata . That same pattern of sequence may be found in another region . With the similarity in the sequencestratigraphy ( sediment layering), Geologist can infer the similarity in age of both strata's.
Fossil contentspresent in different strata; if similar fossil contents found in different regions, geologist can determine the age similarities.
The first picture indicates strata correlation using fossil similarities while the second picture uses the physical continuity like lithology to correlates strata's
Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields
Balinese culture is a mix of Balinese Hindu-Buddhist religion and Balinese customs. It is perhaps most known for its dance, drama and sculpture. The island is also known for its Wayang kulit or Shadow play theatre.
Two statements support the claim that Jenner has been given credit for starting and spreading the practice of immunization:
Jenner became interested in the protective effects of cowpox during his apprenticeship. Here, we are told that Edward Jenner started working on ways to defend the body against diseases as early as during his apprenticeship when he was a teenager. He had been told that farm workers who had contracted cowpox were immune to the smallpox epidemic which was spreading across Europe at the time. He then started working on a vaccine containing cowpox.
Jenner made the first step to erase smallpox. This first step was to try his new smallpox vaccine on a child in 1796. The child did not catch smallpox. In order to get recognition and validation from the authorities, Jenner administered his vaccine to 22 more people, with success.
