How is it possible for two distinct rock layers to derive from the same period?

The rocks can be formed during the same period because a period is such a long period (apologies for the repetition of the word) of time. The obvious case is with igneous rocks: One eruption, lava cools and solidifies, next eruption, cools, solidifies. Two distinct layers of rock from perhaps within the same decade! Else, a rock may be formed at the beginning of a period...for example: agglomerate formed from an eruption is buried deep within the Earth, is compressed and lithifies. Then it is resurfaced due to extreme erosion, perhaps now towards the end of the period. Then an eruption causes lava to cover it, forming another layer of rock. There's two hypothetical situations, however, there may be more.

A common cause of gap in rock layers is what?
A gap in sedimentary layers is known as an unconformity, and occurs as a result of either erosion or a period of non-deposition.
An unconformity that results when new sediments are deposited on eroded horizontal layers is a?
A Disconformity, an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.Types of Disconformity:A Paraconformity is a type in which the separation is a simple bedding plane; i.e., there is no obvious buried erosional surface.A Blended unconformity is a type with no distinct separation plane or contact, sometimes consisting of soils, paleosols, or beds of pebbles derived from the underlying rock.
What are two ways that a rock layer can cause a gap in geologic record?
When rock layers are eroded or when a sediment is not deposited for a long period of time.
Layers formed as sediment builds up over a very long time?
Sedimentary rocks are formed by layers of sediments that build up over along period of time. The rocks are being mixed and compressed together for extended periods of time.
How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
How layers were discovered?
Layers were discovered through observations of rock formations that showed distinct horizontal bands or strata. Geologists found that each layer represented a different period of time, with newer layers on top of older ones. This principle of superposition led to the development of the concept of stratigraphy in the early 19th century.
What are the layers of sedimentary rocks called?
Strata (singular: stratum)

Can a baby died at 6 month inside the mother and she is unaware of it?
yes it is possible. although, most get a distinct smell or odor.. some may even expereance blood loss.. most think its their period.
Why is there layers in the ground?
Because layers form during the period of bog dirt and its been forming from long long ago so layers keep going up ..
Is pregnancy possible a day after period ends?
It is even possible to get pregnant on your period.
Why is the period of a pendulum independent of its mass?
As we derive the expression for period using dimensional analysis, we get T = 1/2pi ./(l/g) In this no mass is present. Hence the conclusion
Is there a comma after a period?
No, a comma is not used after a period. Periods and commas are distinct punctuation marks used for different purposes in writing.
What was era?
An era is "A long and distinct period of history with a particular feature or characteristic."
Is it possible to get pregnant 18 days after period?
Yes it is possible to be pregnant after your period. In all honesty, as long as you have your period, it is possible for you to get pregnant as getting your period means that your female egg cells are circulating and are at work.
Is it possible to get pregnant while you have you period?
AnswerYes, it's all possible and depends on when you ovulate, so make sure you use protection unless you're trying to get pregnantAnswerIt's possible but highly unlikely since during your period you are shedding the layers of the uterine wall that weren't used by a fertilized egg therefore making it almost impossible for an egg to implant if fertilization does occur you have a better chance of getting pregnant about 1 -2 weeks after the first day of your period since that is when most women ovulate
Does ovulating means a woman is having her period?
No, the two are distinct (albeit related) concepts.
