Interesting fact about radiometric dating

Does radiometric dating prove the age of the Earth?

Contrary to the impression that we are given, radiometric dating does not prove that the Earth is millions of years old. The vast age has simply been assumed. 2 The calculated radiometric ‘ages’ depend on the assumptions that are made.

What was the problem with radiometric dating of Mt St Helens?

Return to text. This argument was used against creationist work that exposed problems with radiometric dating. Laboratory tests on rock formed from the 1980 eruption of Mt St Helens gave ‘ages’ of millions of years. Critics claimed that ‘old’ crystals contained in the rock contaminated the result.

Why is Townsvilles geology not suitable for radiometric dating?

Radiometric dates are only accepted if they agree with what geologists already believe the age should be. Townsville geology is dominated by a number of prominent granitic mountains and hills. However, these are isolated from each other, and the area lacks significant sedimentary strata.

Why do rocks in the same area have similar dates?

And the composition is a characteristic of the molten lava from which the rock solidified. Therefore, rocks in the same area which give similar ‘dates’ are likely to have formed from the same lava at about the same time during the Flood.

Does radiometric dating prove millions of years old?

Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations. The presupposition of long ages is an icon and foundational to the evolutionary model.

How is the age of the Earth determined?

The same techniques of radiometric dating have been used on those rocks. All the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample.

How old is the Earth according to radioactive dating?

Instead, radioactive dating indicates that Earth is about 4.5 billion years old—plenty of time for evolution and natural selection to take place. [i] But as we show here, geologists do not use radioactivity to establish the age of certain rocks.

How do Geologists use radioactivity to determine the age of rocks?

How are rocks the same and how are they different?

How are rocks the same and how are they different? It is important that your students begin to understand that rocks are made of minerals. 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.

Why is it important to understand the characteristics of rocks?

It is important that your students begin to understand that rocks are made of minerals. 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.

How does geology affect the shape of a landscape?

The geology of an area is one of the key factors influencing the shape of the landscape: Stronger, more resistant rocks tend to produce highland areas, whereas weaker rocks tend to form lowlands; Whether rock allows water to pass through tells you whether they are permeable or impermeable.

How can you tell if a rock is a sedimentary rock?

If you look at some of the hand specimens you can see the layers in them. The different sedimentary rocks are made up of very small grains of light coloured minerals, some of which (like ‘quartz’) are the same as in the volcanic rock you saw earlier.
