Earth is estimated to be around 4.5 billion years old, based on radiometric dating of meteorites and rocks from Earth's surface. Geologists have used various dating methods to determine the age of Earth, including studying the decay of radioactive isotopes in rocks and minerals.
What else can I help you with?
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
Geologists used it to discover the age of fossil?
Geologists use a method called radiometric dating to determine the age of fossils. This technique measures the decay of radioactive isotopes in the fossil to calculate its age. By analyzing the ratio of parent isotopes to daughter isotopes present, geologists can estimate the age of the fossil.
What can geologists measure the number of to calculate the age of the specimen?
Geologists can measure the abundance of certain radioactive isotopes, such as carbon-14 or uranium-lead, in a specimen to calculate its age. By comparing the ratio of parent isotopes to daughter isotopes in a sample, geologists can determine the age of rocks, fossils, or other geological specimens. This process is known as radiometric dating.
How does a geologist determine absolute age?
Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
What do geoligists use to map the earths interior?
Geologists use seismic waves to map the Earth's interior. By studying how these waves travel through the Earth, geologists can infer information about the composition and structure of different layers beneath the surface. This helps them understand the different layers of the Earth, such as the crust, mantle, and core.

Do geologists learn about earths interior by drilling holes?
No
Who studies rocks minerals and earths forms?
geologists
How do geologists gather evidence about what its like in the earths interior of the earth?
laws of natural
What type of scientist study the earth's forces?
Geologists study the Earths surface
What prevents geologists from studying earths interior?
Depth, temperature and pressure barrier.
How does this principle makes it easier for geologists to understand earths?
I don' t know
What scientist Studies earths land forms and earths rocks?
don't no geologists If focusing on the minerals of a rock then it would be classified as a mineralogist.
In the 1700 what did geologists include about earths land forms?
* landforms are natral features of the earth
What geologists use direct evidence to learn about earths interior?
Geologists use evidence from seismic waves to learn about earth's interior. Geologists record the seismic waves and study how they travel through earth. By Brianna.
Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
What are good science project topics?
Finding out about the earths crust, and what geologists do Finding out about electric cars
