Why are fossils most likely to be found in sedimentary rock samples?
Most fossils are found in sedimentary rock, because igneous and metamorphic rock undergo great heat and pressure when forming, where as sedimentary rocks undergo much less pressure and heat to form, better preserving the fossil
Would you be less likely to find fossils in metamorphic rock than a sedimentary rock?
Metamorphic rock can contain fossils, but since these rocks form under intense heat and pressure where stone flows something like taffy, the fossils will be highly degraded and distorted.Sedimentary rock forms when layers of silt are Why_are_you_less_likely_to_find_fossils_in_metamorphic_rock_than_sedimentary_rockon the bottom of a body of water. When conditions are right, layers form quickly and are not disturbed and little oxygen is present, dead creatures that fall on that bottom can become entombed in preserved at the layers are increasingly compressed, eventually cementing into rock.
How do paleontologists know how old fossils are?
The dating of fossils was originally done by their placement in a geologic column of rock strata. Because of the Law of Superposition, the deeper the stratum, the older it is (in an undisturbed body of rock or sediment). Fossils which were evident in a particular stratum, but missing from other strata were noted as "index" fossils. The presence of these fossils indicated the age of the stratum relative to other layers. The layers of stratum were placed in a geologic column, subdivided, and assigned names based on the presence of different types of fossil organisms.This is the basis of "relative dating" of rock layers and fossils, a dating technique that was in effect until the advent of radiometric techniques in the twentieth century.
When gaseous molecules are compressed they tend to?
They tend to change density, temperature or energy.
Why do students find science subjects difficult?
Because they tend to byheart it.If they learn science by reasoning and thinking it will be the most interesting subject that they would ever find.
When the points on a graph tend to scatter randomly you say they indicate?
No Correlation
What does it mean if two variables have a positive correlation?
If the correlation is positive, as one increases so does the other.
When the points on a graph tend to scatter randomly we say that they indicate .?
That there is no correlation of the collected data.
Fossils in newer layers of the earth tend to resemble current?
organisms
When the points on a graph tend to go upward from left to right you say they indicate?
a positive correlation
When the points on a graph tend to go upward from left to right thay indicate?
a positive correlation
What type of correlation would be expected between shoe size and grade point average?
I would expect a mild negative correlation. Girls tend to have smaller feet and so smaller shoe sizes and they tend t o score better at school.
Is there a correlation between?
Alcoholics tend to consume more alcohol than do others, although that does not define Alcoholism.
Archaeologists tend to find fossils most often embedded in which type of rock?
Archaeologists tend to find fossils most often embedded in sedimentary rock. This type of rock forms from layers of sediment that accumulate over time, preserving the remains of plants and animals. Sedimentary rock is often found in areas where ancient seas, lakes, or rivers once existed.
Fossils in newers layers of earth tend to resemble current?
The principle of fossil succession states that fossils found in younger layers of rock tend to be more similar to current species, while fossils in older layers differ more. This is because newer fossils represent species that have evolved and survived to the present day, while older fossils may belong to species that have become extinct. This pattern helps scientists understand the evolution and biodiversity of life on Earth.
When the data points on a graph tend to go up as they go to the right there is between the two variables?
Positive correlation
Is there a correlation between alcoholism?
Alcoholics tend to consume more alcohol than do others, although that does not define alcoholism.
