Absolute dating involves determining the exact age of a fossil or rock using radiometric methods while relative dating involves comparing which rock/fossil is younger or older than the other without necessarily determining the exact age. Relative dating is significant in determining geological events order.

<h3><u>Answer:</u></h3>

'Relative Dating' and 'Absolute Dating' in the discipline of Petrology (study of rocks) can be compared on three different parameters, viz. method, procedure and merits and demerits.

<h3><u>Explanation:</u> </h3>

<u>Method:</u>

In relative dating, the age of a rock is calculated by comparing it to the age of other reference rock.

Whereas, in absolute dating, the age of the rock is individually calculated through various scientific processes.

<u>Procedure:</u>

The procedure of relative dating majorly consists of a comparison between the fossil's layer of origin and the orientation of the reference fossil or rock.

The procedure of absolute dating is based on determining the quantity of radioactive and non-radioactive isotopes present in the rock.

<u>Merits and demerits: </u>

Relative dating is comparatively less expensive, but it usually fails to deliver the exact static data related to the age of the rock.

Whereas, the method of absolute dating does give out the exact age of the rock, but it proves to be an expensive method overall.

Answer:

Territorial Data.

Explanation:

Territorial data can be defined as a data related to geophysical characteristics. These data is used to know the physical process occurring in the Earth. The territorial data offers a vast amount of data analysis related to geophysical characteristics.

Therefore, the data related to geophysical characteristics is known as territorial data.

Answer:

Earthquakes -the physical phenomena of ground shaking, surface fault rupture, and ground failure and, in some coastal areas, tsunamis. Smaller earthquakes, aftershocks, may follow the main shock, sometimes several hours, months, or even several years later.

Volcanoes-serious damage is restricted to small areas compared with the extent of damage from large floods or great earthquakes. Yet volcanic eruptions can take a high toll in human life and property.
