Question

Which statement accurately describes the rock layers? Layer 8 is older than layer 1. Layer 3 is younger than layer 6. Layer 7 and layer 4 are the same relative age. Layer 2 and layer 9 are the same relative age

Answer 1

Rock layers occur due to sedimentation.

Sedimentation is the process whereby rock particles are carried by erosion and deposited in lower areas.

As sedimentation takes place over the years rock layers are formed.

The oldest layers are the layers at the bottom.

This is because they are deposited the first.

For instance if we have layer 1 upto 8, with layer 8 being the bottom most layer, layer 8 will be older than layer 1.

From the given explanation, the correct answer is :

Layer 8 is older than layer 1

Answer 2

The Layer 8 is older than layer 1 statement accurately describes the rock layers.

Explanation:

• These layers are found in the sedimentary rocks and as per the layer one is younger than other layers and layers two and nine have the same relative ages of fossil deposits

• As each layer of rocks are older than one above the oldest layer is found at the bottom and this is a rule of superimpostion.

• Using isotropic dating technique the decay rate of the formation of organic matter a be traced and that helps to identify the layer of rocks. Other methods like carbon dating for C 14 and N 14 are used to estimate the ages.
