The age of disturbed rocks may have to be determined by?
The age of disturbed rocks can be determined by methods such as radiometric dating, which measures the decay of radioactive isotopes in the rocks, or by studying the index fossils found within the rocks to determine their relative age compared to other layers. Stratigraphic principles can also help in determining the sequence of rock layers and their ages.
The relative age of a rock is?
determined by where it falls in comparison to other rocks in a sequence, using principles such as superposition and cross-cutting relationships. It does not provide an exact numerical age but gives an idea of whether it is older or younger than surrounding rocks.
What is the best indication of a relative age of a rock layer?
The best indication of the relative age of a rock layer is its position in relation to other rock layers. The principle of superposition states that in a sequence of undisturbed rock layers, the oldest layer is at the bottom and the youngest is at the top. Cross-cutting relationships, fossil succession, and original horizontality can also provide clues for determining relative age.
How are Ocean floor rocks are different from continental rocks?
Oceanic crust is composed primarily of the dense volcanic rock basalt. Continental crust is composed primarily of the intrusive igneous rock granite, less dense than basalt.
What is relative and absolute age?
Absolute- Actual Age of a rock Relative- The age of something compared to other things Relative age does not tell how old something is but tells us in what order events have happened relative- the age of a rock or fossil compared to the surrounding rocks and fossil
What is relative aging of a rock?
It's age compared to the ages of other rocks.
Kind of age that compares a rock with other rocks?
relative age

The age of a rock compared to the age of other layer is called?
The age of a rock compared to the age of other layers is called relative dating. This method helps geologists determine the sequence of events that occurred over time by comparing the ages of different rock layers.
What is the definition of relative age?
The geologic age of fossil organisms, rock, or geologic features or events defined relative of each other.
What can you infer about the age of rocks as compared to humans?
relative age
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.
A rock's position within rock layers can tell its?
relative age compared to other rocks in the layers. Over time, sedimentary layers form on top of older layers, with the youngest layer at the top and the oldest at the bottom. By examining a rock's position within these layers, geologists can determine its relative age based on the principle of superposition.
What is a breakage rock?
A Rock Breakage is a rock that breaks when its age is old. They can be found at the Trench where rocks re formed and rocks that are old
What are 2 ways to determine relative age of rock?
Where it is in comparison to other rocks If it contains fragments of another rock, it is definitely younger than it
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.
