Does metamorphic rocks have a higher porosity than sedimentary rocks?
Metamorphic rocks would have less porosity than sedimentary rocks.
Why do metamorphic rocks have a higher porosity than sedimentary rocks?
Actually, it's the other way around. Sedimentary rocks have a higher porosity because of the larger spaces between the rock particles which compose them.
How are sedimentary layers used to date fossils?
Stratigraphic layers can be used to determine the age of a fossil in a simple manner. The layers towards the top of an outcrop are younger (Law of Superposition and Law of Original Horizontality) and the layers near the bottom are older. If a fossil is found in a lower layer then that fossil is older than any fossils found in the higher up layers.
How can you distinguish between sedimentary and metamorphic coal?
Anthracite coal is a metamorphic coal that has a higher luster than any sedimentary coals. It also has the highest carbon content. Otherwise it is very similar to sedimentary coal. Diamond is commonly thought to be the metamorphism of coal but this is largely untrue as the immense majority (near 100%) of diamonds have nothing to do with coal.
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

A scentist finds a rock with fossils at two different levels what she might conclude that the fossils on the bottom are older than the fossils at the top?
The fossil on the bottom would be older because as time goes on rock builds up and buries fossils so the higher it is the more recent it is.
When comparing administrative distances the routing process will choose values over values?
lower then higher
What makes fossils formation most likely?
Fossils fuels form when the dead remains of plants and animals compress with high pressure and heat in the course of millions of years.
What is the greatest common factor that is higher than 10 and 15?
Factors cannot be higher than the numbers you are comparing. The GCF of 10 and 15 is 5.
What type of rock can only be formed from sedimentary rock or igneous rock?
Metamorphic rock can form from igneous and sedimentary rock. It can also form from previously metamorphosed rock into a higher grade metamorphic rock.
Adverbs ending with er?
Adverbs can end with -er when comparing two actions. One example is "higher."
Do scientists use numbers higher than Google plex?
Yes.
