How old is earth and how did scientists find this out?
4.543 billion years. The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years
How could you use index fossils to help you tell the ancient history of the canyon?
Index fossils are useful for dating and correlating the age of rock layers in the canyon due to their widespread presence and rapid evolution. By identifying specific index fossils within the rock strata, geologists can determine the relative age of the layers and establish a timeline for the canyon's formation. This information allows them to reconstruct past environments and geological events, providing insights into the ancient history of the canyon. Additionally, comparing the index fossils found in the canyon with those from other locations can help trace the geological history across different regions.
How much geologic time do layers of rock exposed at the Grand Canyon represent?
The age of the rock layers exposed in the Grand Canyon range from 240 million years to 1,800 million years in age. The surface feature known as the Grand Canyon is thought to be less than 17 million years old.
If in the Grand Canyon walls if a fossil imprint of a leaf is lower than a shell fossil does that mean that the leaf fossil is older than the shell fossil?
Not necessarily. The relative position of fossils in the rock layers can provide clues about their age, but it is not a definitive indicator. To determine the actual age of the fossils, scientists often use radiometric dating techniques and other methods to establish a more accurate timeline.
Topic of debate or conflict in geology?
One ongoing debate in geology is about the mechanisms driving plate tectonics, specifically the role of mantle convection and slab pull in the movement of tectonic plates. Another contentious topic is the timeline and causes of mass extinction events throughout Earth's history. Additionally, there are ongoing discussions about the conditions required for the formation of certain types of mineral deposits.

What is the age and value of a Winchester 94 serial2334381 lever action?
Winchester Model 94 serial number 2334381 is a very early 1959 vintage Carbine. The value can only be deteremined by a visual inspection & evaluation. Bert H.
Why is the Grand Canyon so wide?
The Grand Canyon in Arizona has been carved by the Colorado River for millions of years. It is due to its age that its expanse is so wide.
Is A scientist who researches the age of rock layers in the Grand Canyon studies earth science?
Earth

How many games are featured on the website Cheatcc?
Currently Cheatcc has 5 games featured in the top banner on their website. They are Diablo III, Age of Wushu, Watch Dogs, Defiance, and Splinter Cell.
Would life be different if you never had ice age?
Yes because the great tourist sights and attractions like the grand canyon would be gone
What is the age of the Grand Canyon's rocks?
The oldest rocks at the bottom are nearly 2 billion years old. The youngest at the top are around 250 million years old.
How much will insurance for a Lamborghini Diablo cost in Texas?
this is impossible to answer without knowing your driving history your age the area you live in the value of the car and your coverages. but I would guess as a ball park figure 4 or 5,000.00 a half.
