Are black diamonds more or less expensive than regular diamonds?
Black diamonds are more porous and from younger sedimentary rocks, so they are not as expensive as other diamonds.
What is a synonym for minor?
Younger, Smaller, Lesser. In English schools, if two brothers are present in the same school , they would be referred to as Smith (Major) The older Smith (Minor) the younger.
What is the focus of early communication for infants younger than 12 months?
emotion
Is Perdita Weeks and Honeysuckle Weeks related?
Yes. Perdita is Honeysuckle's younger sister.
Any method of determining whether an event or object is older or younger than other events or objects?
fossil
In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?
Younger than the layer below it.
What fundamental concept states that in a horizontal sequence of conformable sedimentary strata each higher bed is younger than the bed below it?
law of superposition
What. Type of unconformity consists of tilted sedimentary rocks that are overlain by younger more flat lying sedimentary rocks?
angular unconformity
What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?
The intrusion is younger than the overlying sedimentary rock.
How is the law of superposition is used to date fossils?
Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.
Where would you typically find younger rocks?
If you are talking about sedimentary rock, and the idea of relative dating, then the younger rock would be on top closer the the surface.
Younger layers of undisturbed sedimentary rock are above older layers according to?
the principal of sedimentarianism
What is the age of an igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.
What is the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passed?
It is younger.
What is the The age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes?
It is younger.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
Because of geologic events such as plate tectonics and volcanism, suitable material for radiometric dating, such as volcanic tuff, solidified lava, and igneous intrusions have been found as layers on, in, and cut through layers of sedimentary rock.Intrusions are always younger than the rock body they penetrate, meaning that the sedimentary rock in which intrusions are found will be older than a radiometrically dated sample of the intrusion. Lava flows and volcanic ash which form layers in rock will be younger than the rock below and older than the rock above. The solidified intrusions and lava flows can be dated with radiometric techniques.The radiometric dating of suitable rocks (i.e. igneous or metamorphic) in proximity to their sedimentary counterparts, therefore allows the sedimentary rock to be dated as well.
Is it true to say that radioactive istopes in clastic sedimentary rocks always predict an age that is younger than the sedimentary rock?
That would not be true due to the fact that sedimentary clastic rock is composed of particles of pre-existing rock.
