Gaining estimates of ages of rocks is crucial for establishing not only the history of geological events but also for determining the rates of geological processes. It is possible to establish the relative order of events in some rocks.

What is the importance of studying the age of rocks?

Geologists study rocks because they contain clues about what the Earth was like in the past. We can assemble a historical record of a planet and trace events that occurred long before humans roamed our planet.

Why is the dating of rocks and fossils an important task?

Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earths surface to determine the relative ages of geological events preserved in the rock record.

What is the importance of rocks?

Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily.

What can rocks tell us?

Rocks tell us a great deal about the Earths history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.

What makes rocks special?

Different rocks have different characteristics because of their minerals, the ways in which the rocks were formed, and the processes that acted on the rocks since they were formed. They will then use their observations of the rocks to identify a particular rock from a collection.

What is the important of rock?

Rocks have a broad range of uses that makes them significantly important to human life. For instance, rocks are used in construction, for manufacturing substances and making medicine and for the production of gas. Rocks are also extremely vital to scientists as they provide clues about the Earths history.

What story do rocks tell?

Each rock layer tells a story of how it was formed in its environment such as a desert, river or seabed. If there were animals or plants around, then often these have become fossilised within the rock layers.
