Answer:
The Hadean eon represents the time interval between 4.6 billion to 4 billion years back. It is marked by the initial formation of the earth , right from the time of gathering and accumulation of interstellar dust particles and gases, and there was frequent collision between the planetesimals of relatively larger in size. The core and the crust formed and started to become stable and also gradually led to the formation and expansion of the ocean and the earth's atmosphere.
This is how the earth gradually started to form and develop and took the shape during the time interval between 4.6 billion to 4.2 billion years old, and where the oldest rocks found on earth is dated from about 4.2 billion years in the past.
In 1914, Archduke Franz Ferdinand of Austria and his wife Sophie are shot to death by a Bosnian Serb nationalist during an official visit to the Bosnian capital of Sarajevo. The killings sparked a chain of events that led to the outbreak of World War I by early August.

The correct answer would be B. Nigeria
Answer:
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
Explanation:
This problem can be solved as a simple rule of three, with the mathematical conversion from feet to m.
Each ft has 0.3048m. So how many m are there in 7.6ft?
1 ft - 0.3048m
7.6ft - x m
So
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
