The type of sedimentary rock in which the older rocks, unless disrupted, are on the bottom is called a fossil-rich limestone. This rock contains fossil remains of prehistoric organisms.

What is a sedimentary rock in which the older rocks unless disrupted are on the bottom?
Nonfoliated rock is the answer thank you but this may not be Right QUESTION MADE NO SENSE
What rock is made of older rocks from a period of time?
sedimentary
What are sedimentary rock composed of older rocks called?
Clastic
How is sedimentary rocks like the rings in a tree?
Just as the rings in a tree get older as you count towards the centre of the trunk, so layers of sedimentary rock are older the further down a sequence you look.
What is sedimentary rock called composed of older fragments of rock?
Clastic
Which is older igneous or sedimentary?
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.
If a sedimentary rock contains inclusions of metamorphic rock which rock is older?
The metamorphic rock would be older, because in the sedimentary rock's formation that is caused by collected sediment taking years to harden and turning into a rock, the metamorphic rock would have already been considered metamorphic when traces of it came into the sedimentary.
Are the rock formations in the grand canyon older at the top or bottom of the canyon?
The rock formations at the bottom are older.
Is the sedimentary rock strong?
That depends on the rock. Some sedimentary rocks are used as construction material, or as raw material for different kinds of industries. Older sedimentary rocks have a scientific value as well, as ages of fossils can be determined by studying them.
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...
Why is the sedimentary rock layer at the bottom of a canyon older then a sedimentary rock layer at the top of a canyon?
As a rule, the oldest rocks of layered rock strata are always at the bottom, the youngest at the top. The rock at the bottom was the first to form. Layers of weathered and eroded particles (sediments) or igneous material in the form of lava, add additional weight over time, which causes the mass to sink and compress, forming new rock layers. When running water erodes a canyon, the geologic history of the land is revealed in the rock layers.
Younger layers of undisturbed sedimentary rock are above older layers according to?
the principal of sedimentarianism
