What rock cycle means?
a reapedly of layers forming
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 is sedimentary rock like?
it is a rock that has been formed by weathered particles forming layers and coming together to make a rock
Layers of rock that bend can produce a downward fold known as?
An anticline. This is a geological feature where the layers of rock are bent upward in an arch shape, forming a convex structure.
What is a trough of rock layers called?
A trough of rock layers is called a "syncline." In geology, a syncline is a downward-curving fold where rock layers dip inward toward the center, forming a U-shaped structure. This contrasts with an "anticline," where rock layers arch upward. Synclines are important in understanding the geological history and structural features of an area.
What is the difference between strata and stratification?
Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.
What happens when the pressure snaps the rock?
A "fault plane is created, rock layers move relative to one another (rock can melt in the fault plane forming Pseudotachylyte or Mylonite) and energy is released as an earthquake.
When looking at a rock column where would you expect to find the oldest rock fossils?
In a rock column, the oldest rock fossils are typically found at the bottom layers. This is due to the principle of superposition, where sedimentary layers are deposited over time, with newer layers forming on top of older ones. Thus, as you move downward in the column, you encounter older geological formations and their associated fossils.
What does older layers mean?
Layers of rock that were laid down longer ago than other layers. The law of superposition states the the layers deeper down are the oldest.
What states that younger rock lie above older rock?
The principle that younger rock layers lie above older rock layers is known as the Law of Superposition. This geological principle is fundamental to understanding the relative ages of sedimentary rock layers and is used by geologists to interpret Earth's geological history. It assumes that sedimentary rocks are deposited in horizontal layers, with each new layer forming on top of the previous ones. This law is crucial for stratigraphy and helps in reconstructing the sequence of geological events.
What is cemetation mean?
Sedimentary Rock That Forms Where Of Organisms Are Deposited In Thick Layers.
How do permeable and impermeable rock layers contribute to the formation of a spring?
The water sinks through the ground through permeable rock and is concentrating when it arrives to impermeable rock. When due to erosion the impermeable rock carrying water is exposed, the water appears as a spring.
