Toughness is not an ideal descriptive term when it comes to rocks, but there is a correlation between age and the degree of breakability, crumbliness, or friability. The longer a rock has been exposed to erosive elements like acidic rainwater, freezing, heat from the sun, etc., the more it has been subjected to a weakening of the bonds created by mineral structures. It all goes back to the rock cycle, the continual transformation of one material into another.
What else can I help you with?
What is the The age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes?
It is younger.
What is the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passed?
It is younger.
What is difference between relative and absolute age?
In terms of geology, Relative Age is the age of an object in relation to the ages of other objects. Layers of rock, called strata, show the order of events that took place in the past and Absolute Age is the numerical age of an object or event.
The agee of a rock in years is the rocks numerical age or?
The age of a rock in years is its numerical age or absolute age. This measurement provides a specific time frame for when the rock was formed, typically determined through radiometric dating techniques. In contrast, relative age indicates the rock's age in relation to other geological events or formations.
What is the age of an igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.
What is the difference between the relative age and absolute age of rocks?
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
The age of a rock compared with the age of other rocks?
The age of a rock can be determined through radiometric dating techniques, comparing the ratios of certain elements in the rock to known decay rates. By analyzing the age of the rock in relation to the ages of other rocks in the surrounding area or in similar geological contexts, scientists can establish the relative age of the rock within the geological timescale.
Do isotopes determine the size or age of a rock?
Isotopes can be used to determine the age of a rock through radiometric dating, but they do not determine the size of the rock. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate its age based on the rate of radioactive decay.
What are some characteristics of relative age?
Relative age indicates the position of something in relation to other things. It does not provide an actual age or date, but rather a comparison of how old something is in relation to something else. Relative age is often used in geology to determine the age of rock layers or fossils.
What does relative dating provide for the age of a rock layer or fossil?
Relative dating provides an estimated age of a rock layer or fossil based on its position in relation to other rock layers or fossils. It helps determine the sequence of events in Earth's history, but does not provide an exact numerical age.
What is the difference between relative and absolute age?
Relative age does not assign a number to an age, but is only used to say, for example, whether rock A is older than rock B. Absolute age actually assigns a number, for example "this shale is about 300 million years old."
What is the difference between relative ages of and relative position of rocks?
Age is how old the rock is relative to other rocks, position is where the rock is in relation to other rocks. Tectonic motion and other forces can easily turn a portion of the Earths crust upside down resulting in older rock lying above younger layers.
