### 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.

### Why do radiometric dating methods give inflated ages?

We now have a good idea why most radiometric dating methods give inflated ages: there was at least one episode of accelerated radioactive decay in earth’s history. This is the only reasonable way to make sense of the abundance of helium found trapped in various rocks. The abundance of helium indicates that much radioactive decay has happened.

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

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. They instead use selected radioactivity results to confirm what they need to see.

### Are radiometric ages absolute or relative ages?

Many textbook authors consider radiometric ages as absolute ages. However, as you will soon learn, these techniques stray far from absolute dates, though they may reveal relative ages of some rocks. Today’s evolutionists base their age of the Earth on their interpretation of radioactive elements.

### Does radiometric dating prove the age of the Earth?

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. T he 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 is radioactive dating used to date rocks?

When scientists date rocks from our planet this way, the oldest dates they find are 4.5 billion years. By dating the lava flows above and below a fossil find, scientists can put exact boundaries on the maximum and minimum age of that fossil. With radioactive dating, scientists can now get within a few percentage points of the actual date.

### How do we age date a planet?

Based on our study of meteorites and rocks from the Moon, as well as modeling the formation of planets, it is believed (pretty much well-established) that all of the objects in the Solar System formed very quickly about 4.56 billion years ago. When we age date a planet, we are actually just dating the age of the surface, not the whole planet.

### Using relative and radiometric dating methods, geologists are able to answer the question: how old is this fossil? This page has been archived and is no longer updated Dating Rocks and Fossils Using Geologic Methods

### Is radiometric age dating reliable?

Radiometric age dating should no longer be sold to the public as providing reliable, absolute ages. Excess argon invalidates the initial condition assumption for potassium dating, and excess helium invalidates the closed-system assumption for uranium dating. The ages shown on the uniformitarian geologic time scale should be removed.

### 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.

### What types of rocks can be used to determine radiometric ages?

Igneous (crystalline) rocks—those that have formed from molten magma or lava—are the primary rock types analyzed to determine radiometric ages. For example, let’s assume that when an igneous rock solidified, a certain mineral in it contained 1,000 atoms of radioactive potassium ( 40 K) and zero atoms of argon ( 40 Ar).

### How old is too old for the radioactive carbon method?

Such an age far exceeds the limit of the radioactive carbon ( 14 C) method, which in theory extends to artifacts less than 100,000 carbon years old.
