What else can I help you with?
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.
How was the age of rocks in ocean basins determined?
The age of rocks in ocean basins was determined through radiometric dating of volcanic rocks, which provides the absolute age of the rocks. Analyzing the magnetic properties of the rocks and the orientation of magnetic minerals helped in dating the rocks based on changes in Earth's magnetic field over time. Additionally, studying the distribution of fossils in the rocks provided relative dating information based on the known ages of the fossils.
How do you determine the age of igneous rocks?
Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.
When is it earths birthday?
We will never know the exact birthdate but April 22 is Earth Day.
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 age of the earth's crust can best be determined from the studies of?
The age of the Earth's crust can be best determined using radiometric dating techniques on rock samples collected from the crust. By measuring the decay of radioactive isotopes in these rocks, scientists can calculate the age of the crust. Additionally, studying the magnetic properties of the rocks can provide further insights into the age of the Earth's crust.
A relative age of the rocks of the earths crust can be determined by using the laws of?
superposition a&c- Jackie
How old was osiris when he became king?
An exact age cannot be determined, as this is mythology and not literal history.
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.
What evidence supports the hypothesis that Earth is 4.6 billion years?
The age of Earth is determined through radiometric dating of rocks and meteorites, as well as studying the decay of radioactive elements, such as uranium and thorium, in Earth's crust. Additionally, analysis of lunar rocks from the Apollo missions provided further evidence supporting the estimated age of Earth at 4.6 billion years.
What us the possessive pronoun in the rocks'?
The possessive pronoun that takes the place of the plural, possessive noun rocks' is theirs.Example: These rocks' age was determined by measuring radioactive decay. The X marked on this timeline is theirs.Note: The possessive pronoun should not be confused with the possessive adjective 'their'.Example: These rocks' age was determined by measuring radioactive decay. Their age is marked on this timeline with an X.A possessive pronoun takes the place of a noun that belongs to someone or something.A possessive adjective is placed before a noun to indicate that the noun belongs to someone or something.
How old are igneous rocks?
Igneous rocks do not have a specific age. They are formed from lava or magma cooling and solidifying, which can happen at any point in time. The age of an igneous rock can be determined through radiometric dating techniques.
