How can grains of sand become part of sedimentary rock?
the compaction and heat under the layers of the Earth causes this process to occur
How do we know if rock layers are undisturbed?
The rock layers will be easily visible.
What the different forces that the rock layers are subjected to?
The rock layers are subjected to many different types of forces. Some of them are:1. Weathering2. Climate change-torrential rainfall,scorching heat and freezing of water between the cracks formed in the rocks,etc.3.vibrations caused by the hoofs of different types of creatures
What kind of rock is made up of layers?
Sedimentary Rock is made up of layers of different rocks.
How can ingneous rock disturb sedimentary rock layers?
Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.
What are gaps in rock layers called?
Gaps in rock layers are called unconformities.
What are missing rock layers known as?
Unconformities. =)
Gaps in rock layers that develop when agents of erosion remove existing rock layers?
Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
Erosion is one of the major causes of missing rock layers known as?
Unconformities. =)
What characteristic most directly distinguishes an angular unconformity from a nonconformity?
Angular unconformities separate rock layers along nonparallel surfaces
Which is the correct answer for this questionThe law of ______states that new rock layers are always deposited on top of existing rock layers.?
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
If the tops of the rock layers in the figure below were eroded and then deposition started happening again what kind of unconformity would have formed?
We can not see you diagram so can not answer your question. However unconformities come in these typesDisconformitiesNonconformitiesAngular unconformitiesParaconformitiesButtress unconformitiesBlended unconformities
How do you suppose geologists in the field find clues about the distribution of rock types?
Discontinuity surfaces (bedding planes and various types of unconformities), significant changes in mineralogy or grain size or changes in the types of fossils present in the rock may all help identify differing rock layers.
What can cause an unconformity?
Unconformities occur when erosion wears away rock, or when rock deposits are never formed.
What are the different types of unconformities?
An unconformity is defined as a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. The different types of unconformities include disconformity, nonconformity, angular unconformity, paraconformity, buttress unconformity, blended unconformity, and biconformity.
How do uncomformitys form?
Unconformities occur when either erosion wears away rocks, or rock deposits never formRead more: Unconformity - Angular Unconformities, Disconformity, Nonconformities, An Ongoing Process http://science.jrank.org/pages/7092/Unconformity.html#ixzz0gMoz1vmU
If the same types of fossils are found in two separate rock layer its likely that the two rock layers?
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers ____.
