Luisa has two older brothers and a younger sister. She had been learning about how to describe the ages of rocks. After thinking about it, she realized she could compare people's positions in her family in the same way that scientists compare rocks. Which geology term would describe the way Luisa compares the positions of people in her family? a. absolute age
b. rock layers
c. relative age
d. superposition

c. relative age

Explanation:

Relative age is a method of describing the age of rocks based on their order of appearance in the geologic column.

Events are denoted by their position in the column.

The premise of most of the assumptions used relative age determination is based on stratigraphic laws. Absolute age gives numeric ages to rocks.

Since Luisa is comparing the age of people based on their position in her family, she is using the concept of relative dating.

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

The answer is the first option just took the test
