__________________ dating involves age-dating fossils with known time periods grouped into four eras that represent distinct age
RSB [31]

According to the research, the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

<h3>What is Relative dating?</h3>

It consists of ordering fossils or events in a proper formation sequence from the oldest to the most modern, it tends to be used as a method for making chronologies, the ordering of events, fossils or rocks.

Since it does not give an exact or approximate date, they can only give us a fairly long period of time, or in their case a temporal ordering of the fossils.

Therefore, we can conclude that according to the research,  the correct option is Relative dating. It involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of earth.

AURORKA [14]

Answer:

95 N right

Explanation:

Given that,

Both Elizabeth and Steven pushes the cabinet to the right. Elizabeth applies 5 a force of 40 N and Steven exerts a force of 55 N.

As both forces are acting in same direction, they will add up. Net force is given by :

F = 40 N + 55 N

F = 95 N in right direction

Hence, the correct option is (d) "95 N right".
