What are the comparative uses of relative versus absolute age in determination of rock units?
Relative Age- is basically the determination of the relative order of past events without knowing their absolute age. This is done through the observation of fossils, lithology's, and the Law of superposition. These observations can be used to correlate one stratigraphic column with another. For example if you find an Index Fossil (which is a fossil used to identify geologic periods) such as Bathyurus extans in a stratigraphic layer then you can conclude that the layer was deposited during the Ordovician period between 488 and 433 million years ago. Also through the Law of superposition you can conclude that any rock layer above will be younger than 433 million years and any rock layer below will be older than 488 million years.
Absolute age- is the determination of an approximate computed age using physical or chemical properties of a rock. Some examples are Radiocarbon dating and Potassium-Argon dating. These dating techniques give an actual computed value for the age of a rock. These values are usually associated with an error correction. For example on the Geologic Time Scale the Early Cambrian period is assigned a value of 542.0 +/- 1.0 in millions of years on the geologic time scale.
Relative Age is allot more commonly used than absolute dating because absolute dating is expensive and time consuming. The ages obtained from relative dating are more than sufficient to support the geologic analysis of an area.

What two star characteristics does Hertzsprung Russell diagram compare?
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
When was Joe Versus the Volcano made?
The movie Joe Versus the Volcano came out in 1990.
What variables are on the H-R diagram?
The Hertzsprung-Russell diagram is a scatter graph of known stars. It shows the absolute magnitudes (actual brightness at a set distance) versus the spectral type or classification (which is effectively what their temperature is). Stars, when plotted onto this graph, tend to fall into set patterns. The position of a star within a pattern (or sequence) can give further information, such as how old the star is.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
Why phenolpthalein use first before methyl orange?
Phenolphthalein is typically used first in acid-base titrations because it has a clear color change from colorless to pink around a pH of 8.2 to 10, making it ideal for detecting the endpoint of strong acid versus strong base titrations. Methyl orange, on the other hand, changes color from red to yellow between pH 3.1 and 4.4, which is better suited for strong acid versus weak base titrations. Using phenolphthalein first allows for a more precise determination of the endpoint in higher pH ranges before transitioning to methyl orange for lower pH applications.
What are two radioactive elements used to determine absolute age?
The half-life of Carbon 14 and radionuclides are used to estimate the absolute (versus relative) age of pre-history items.
What is the difference of relative density versus density?
Absolute versus relative densityDensity is mass per unit volume. To determine an object's density (absolute), simply divide its mass by its volume. For example, 1000 kilograms of water occupies one cubic meter. We can therefore say that water's density is 1000 kilograms per cubic meter (kg/m3), which equals one kilogram per liter (kg/L), which also equals one gram per milliliter (g/mL). Now, let's say you have some other substance that also occupies one cubic meter but weighs 2000 kilograms. It has a density of 2000 kg/m3. In other words, relative to water, the substance is twice as dense as water. Now you have an idea of what relative density is.If we use water as a reference, we can compare other substances' densities to the density of water. Simply divide the substance's absolute density by the absolute density of water to get the relative density of the substance (relative to water). Relative density is a unit-less quantity; it is just a number. If a substance is denser than water, its relative density will be greater than one. If it's less dense than water, it will have a relative density less than one.Relative density is also known as Specific Gravity.
Will wood float on water?
It depends on the relative density of the wood versus the water. In general, yes.
Even though this star has an absolute magnitude greater then that of sirius it looks dimmer from earth since it's 100 times farther away?
Yes, the star with the higher absolute magnitude will appear dimmer from Earth if it is located farther away. This is because brightness decreases with distance due to the inverse square law of light, meaning that a star will appear dimmer the farther it is from the observer.
Why can nature versus nurture also be known as?
Nature versus nurture can also be known as the debate between genetics and environment in shaping human behavior and traits. It refers to the ongoing discussion about the relative influences of inherited factors (nature) versus environmental factors (nurture) in determining individual characteristics.
How do you read a HR diagram?
scatter graph of stars showing the relationship between the stars' absolute magnitudes orluminosities versus their spectral types orclassifications and effective temperatures.
What do sociologist mean when they say deviance is relative?
When sociologists say deviance is relative, they mean that what is considered deviant behavior varies depending on the culture, time period, and social context. What is considered deviant in one society may not be in another. It emphasizes that norms and values are not fixed and can change based on different factors.
What is the theme of leningen versus the ants?
The theme of "Leiningen Versus the Ants" is the conflict between man and nature, particularly the power of nature to overcome human efforts and the importance of ingenuity and determination in facing seemingly insurmountable challenges. It explores themes of survival, perseverance, and the limits of human control over the environment.
