The Earth’s crust has formed over millions of years and is still present today, and the time that it takes to form is dependent on the type of rock formation that is being studied. For example, if you want to know when the crust formed, then you will have to figure out what rocks were formed first.

Once you have figured out what rocks were formed first, then you can then look at the different types of rocks that are formed, and how they formed. Then, it is quite easy to figure out how long the rocks have been around.

Geologic time scales were first put together to help scientists understand where rock formations and sedimentary layers are located in the Earth’s surface. This helps scientists determine how old a rock formation is. Many rocks will have the same composition, or they will have varying compositions depending on where they are located.

In addition to helping scientists understand how long a rock formation has been around, a geologic time scale worksheet can also tell us how many rocks have been formed in a given area at one time. This information helps scientists figure out the history of a given area, as well as how it has changed over the years.

The same is true for different types of sedimentary rock being formed. It can be helpful to know how long a sedimentary rock formation was formed, because when you are trying to figure out how old a sedimentary rock formation is, this will help you figure out how long ago the sedimentary rock formation began to form.
