Question

The Table shows different geologic time periods: Period Number of Years Ago Jurassic 2.08 ⋅ 108 Silurian 4.38 ⋅ 108 Tertiary 6.64 ⋅ 107 Triassic 2.45 ⋅ 108 Order the time periods from oldest to youngest

Answer 1

Answer: Required order would be

Tertiary  > Silurian  >   Triassic  >  Jurassic

Step-by-step explanation:

Since we have given that

Period                          Number of years ago

Jurassic                        $2.08\times 10^8$

Silurian                          $4.38\times 10^8$

Tertiary                          $6.64\times 10^8$

Triassic                          $2.75\times 10^8$

We need to write in the order from oldest to youngest.

Since according to age, we get that Tertiary is the oldest and Jurassic is the  youngest among them.

So, Required order would be

Tertiary  > Silurian  >   Triassic  >  Jurassic
