Answer:
The correct answer about geologic time scale is that, it presents the correct sequence of events in the history of the earth.
Geologic Time scale is being recorded in the history of geologics. It is being broken into smaller and larger subdivisions and this helps us to know how events fit together.
In order to study the major events which are found in geologic history we should study the rock strata which is found around the world.

Answer:
The answer to your question is E = 419.435 J
Explanation:
Data
Mass = m = 2.004 g
Temperature 1 = T1 = 89°C
Temperature 2 = T2 = 139°C
Specific heat of water = Cp = 4.186 J/g°C
Energy = E = ?
Formula
E = mCp(T2 - T1)
Substitution
E = (2.004)(4.186)(139 - 89)
Simplification and result
E = 8.3887(50)
E = 419.435 J
