How is the relative age of a rock layer or fossil different from the absolute age of a rock layer or fossil?

Answers

Answer 1
Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.
Answer 2
Explanation:
An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation). So in the end you can say this fossil is 50 thousand years old (always with an associated uncertainty). We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision.
Relative dating is like looking at a multi-layered cake. The base layer must come first, then the second and then the third. So I can say the second layer is younger than the first and older than the third but I have no idea whether the cake is 5 minutes or 5 million years old. Relative dating is used commonly when looking at the relative order of geological events.
What can complicate relative dating is when the strata is not the right way up! Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!

Contrast relative-age dating with absolute-age dating.

Answers

Answer:

Absolute dating is more precise than relative age dating

Explanation:

Relative age Dating

It is relative and hence is less precise

It is not scientific but more of observational nature where the age of the fossil is determined by looking at the position of the rock layers.  

Shows relative order in which the oldest layer is at the bottom and the youngest lies at the top

Absolute age Dating

It determines the numeric age of fossil in numbers and hence it is more precise

Scientific in nature as the age is determined by using radiometric dating

What is culture ?

Culture, which derives from the Latin colere, which means "to cultivate," refers to the patterns of human activity and the symbolic frameworks that give those patterns meaning and importance. "Systems of symbols and meanings that even their creators contest, lack fixed boundaries, are constantly in flux, and interact and compete with one another" is how cultures can be understood.

A population's collective ways of life, including its institutions, beliefs, and artistic expressions, are collectively referred to as its culture. A society's whole way of life has been referred to as its culture. As a result, it incorporates systems of belief as well as standards of behavior, such as law and morality, and rules of conduct, dress, language, religion, rituals, and culture.

Answers

Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches. ... The movement of the wind is a result of differences in air pressure over the land and the ocean. Warm air is less dense and rises, therefore cool air is more dense and sinks. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
