How is the relative age of fossils determined?
it can be determined by radiometric dating* It is done by Carbon dating. Carbon is the basic basic building block of life and has an amazing memory. Rays of the Sun which are radioactive enter our atmosphere and collide with Nitrogen atoms to create the radioactive isotope, Carbon-14. * We have both Carbon-12 and Carbon-14 in our bodies at all times and we continue to gain more every day that we live. Fossils are dated this way. * The Carbon-14 decays with its half-life of 5,700 years, while the amount of Carbon-12 remains constant in the fossil. By looking at the ratio of Carbon-12 to Carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely. * Once dates for geologic layers have been established, the age of fossils within that layer can be inferred. When the age of fossils has been established, they can be used to date other geologic layers. This is commonly done in the oil and gas industry.Edit: Carbon dating can only be used on materials that are less than about 50,000 years old, so it can't be used on fossils.The ages of fossils are generally constrained by radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their containing strata within the lithological sequence.
How many fossil kits with 12 samples each have the same number of fossils as 30 fossil kits with 8 samples each?
20
What is the maximum depth at which fossils are found in the earth's crust?
It depends on where the rock is situated, some fossils are found at the surface, some are found up mountainsides, others are found deep in coal mines. Most fossils are found near the surface as it is easier to find them there.
What is the ratio of 16 inches to 4 feet?
By unit of length and distance and conversion ,we can say that 1 feet =12 in 4 feet =48 in ratio : 16 :48 1:3
What is unique about ash-fall fossils?
I got this: "Unlike most fossil deposits, which consist of scattered bones accumulated over extended periods of time, the ash bed contains mostly articulated remains with bones still joined together in the proper order." From here: http://www-museum.unl.edu/research/vertpaleo/ashfall.html

What is the ratio of 0.12?
Means for every 100 units of one, you add 12 units of 2. Or a 20/3 ratio (expressed in percent).
What is 12 seconds to 1 minute as a ratio?
To express 12 seconds to 1 minute as a ratio, we need to convert both units to the same time measurement. Since there are 60 seconds in 1 minute, the ratio would be 12:60. To simplify this ratio, we can divide both numbers by their greatest common factor, which is 12. This simplifies the ratio to 1:5.
What is the ratio of feet to inches on a measuring tape?
There are 12 inches to 1 foot, so the ratio is 12 to 1.
What are egg fossils in Fossils Fighters?
wii channel or get all vivos to rank 12
What is the ratio 12 and 36?
The ratio of 12 to 36 can be expressed as 12:36. To simplify this ratio, divide both numbers by their greatest common divisor, which is 12. This results in a simplified ratio of 1:3.
How do you get the ratio of 3months to a year?
To find the ratio of 3 months to a year, first convert the time periods into the same unit. Since a year has 12 months, the ratio can be expressed as 3 months to 12 months. This simplifies to 3:12, which can be further reduced to 1:4. Thus, the ratio of 3 months to a year is 1:4.
What is the ratio 21 and 12?
The ratio of 21 to 12 can be expressed as 21:12. To simplify this ratio, you can divide both numbers by their greatest common divisor, which is 3. This simplifies the ratio to 7:4. Therefore, the simplified ratio of 21 to 12 is 7:4.
What Is The Ratio Of 12 to 24?
The ratio of 12 to 24 can be simplified by dividing both numbers by their greatest common divisor, which is 12. This results in a simplified ratio of 1 to 2. Thus, the ratio of 12 to 24 is 1:2.
What is the ratio of 3 weeks and 12 days?
To find the ratio of 3 weeks to 12 days, we need to convert both time periods to the same unit. Since 1 week is equal to 7 days, 3 weeks is equivalent to 3 * 7 = 21 days. Therefore, the ratio of 3 weeks to 12 days is 21:12, which simplifies to 7:4.
What is the ratio of 12 to 10?
12/10 = 6/5 The ratio is 6:5
What is the ratio of 12?
It is 12 to 1.
