What else can I help you with?
Organism that formed index fossils when?
Short spans of geologic time
What is formed when rocks bend under stress but do not break?
Folds are geologic structures that are formed when rocks bend but do not break.
Is caldera considered a rock?
No. A caldera is a type of geologic structure formed by the collapse of a volcano.
What geologic processes formed most of california's nonmetallic mineral resources?
Mountain building
What era does sedimentary rock come from?
Sedimentary rock was, and is, being formed in all geologic eras.
How can you date a walrus tusk?
Dating a walrus tusk usually involves using radiocarbon dating techniques, which can determine the approximate age of the tusk by analyzing the decay of radioactive carbon isotopes present in the tusk. This method can provide an estimation of when the walrus lived and subsequently when the tusk was formed.
What is the dating system that describes only the order in which rocks where formed?
Relative dating. (do your own study island)
Which type of geologic event has to occur to create an angular unconformity?
An angular unconformity is formed when older tilted or folded rock layers are eroded, creating a flat surface, and then new horizontal layers are deposited on top. This type of geologic event typically involves periods of uplift, tilting, and erosion followed by subsidence and deposition.
How was the Llano Uplift rock formed?
The Llano Uplift is a roughly circular geologic dome of Precambrian rock, primarily Both may have been formed around the time of the Ouachita orogeny.
Can metamorphic rocks be formed from other metamorphic rocks?
Yes, in a sense. Rocks can be metamorphosed multiple times, by different geologic events.
When two geologic plates are moving away from each other what happens?
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
What happens to the existing geologic balance when rocks are formed?
When rocks are formed, they can disrupt the existing geologic balance by altering the distribution of minerals and materials within the Earth's crust. The processes of sedimentation, metamorphism, and volcanism contribute to the creation of new rock formations, which can change landforms, influence erosion patterns, and impact the hydrology of an area. Additionally, the formation of new rocks can lead to the recycling of older materials, creating a dynamic interplay that continuously reshapes the geologic landscape.
