What feature is formed when lava cuts across rock layers and hardens?
A dike is formed when lava cuts across rock layers and hardens. This igneous intrusion results in a narrow, tabular rock formation that can be exposed on the Earth's surface due to erosion or uplift.
When magma cuts across another rock and hardens the resulting formation is called an?
When magma cuts across another rock and hardens, the resulting formation is called an "intrusion" or "igneous intrusion." This occurs when molten rock, or magma, forces its way into pre-existing rock layers and solidifies, typically forming structures such as dikes or sills. Intrusions are important in understanding geological processes and the history of the Earth’s crust.
What does rubbing a rock against porcelain do?
Rubbing a rock against porcelain can test the hardness of the rock. If the rock leaves a scratch on the porcelain, it indicates that the rock has a higher hardness level than the porcelain. This can help in identifying the relative hardness of the rock based on the Mohs scale.
What kind of rock cuts all other rocks?
Diamond is the hardest natural material and can cut through other rocks. Its exceptional hardness is due to its unique crystal structure.
Which pluton cuts across the existing rock layers?
A pluton that cuts across existing rock layers is known as a cross-cutting pluton. This occurs when magma intrudes into pre-existing rock formations and solidifies, creating an igneous body that disrupts the original stratigraphy. The principle of cross-cutting relationships in geology states that the features that cut across others are younger than the rocks they intersect. Examples of such plutons include dikes and stocks.
What is the feature that is formed when lava cuts across rock layers and hardens?
Lava that cuts across rock layers hardens to form a feature called a Dike.
What is cross-cutting relationship?
A crosscutting feature occurs when a rock or body of sediment cuts across, through fractures, faults, or magma. Any feature that cuts across must be younger than the rock or sediment that it cuts across.
What is the narrow tube-like body of intrusive igneous rock that cuts across existing rock called?
What is the narrow tube-like body of intrusive igneous rock that cuts across existing rock calle
What is a volcano dike?
an intrusive body of magma that cuts across layers of rock
What feature is formed when lava cuts across rock layers and hardens?
A dike is formed when lava cuts across rock layers and hardens. This igneous intrusion results in a narrow, tabular rock formation that can be exposed on the Earth's surface due to erosion or uplift.
What principal involves an intrusive rock body younger than the rock into which it intrudes?
The principle you are referring to is the principle of cross-cutting relationships. It states that any feature that cuts across a rock must be younger than the rock it cuts across. This applies to intrusive rock bodies, which are younger than the rocks they intrude into.
Which is older a dike or the rock layers the dike cuts across?
Dikes are always younger than the surrounding rock layers. The same holds true for any kind of intrusion. It will always be younger than anything that it is intruding into. To put it simply, you can't force an object into a bed of rock unless the bed of rock is already there.
What is the relative age of a fault that cuts across three horizontal sedimentary rock layers?
The relative age of the fault is younger than the sedimentary rock layers it cuts across. The fault must have formed after the deposition of the sedimentary rock layers, as it disrupts them.
What is the classification of a rock that cannot ba scratched with a fingernail but can be scratched with a coin?
The rock would likely be classified as having a hardness of around 3.5 on the Mohs scale of mineral hardness. This would indicate that the rock is softer than minerals like quartz but harder than minerals like calcite. Examples of rocks with this hardness include gypsum and calcite.
How is it that crosscutting feature is always younger than the rock layers in cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
How is it that crosscuting feature is always younger than the rock layer it cuts across?
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
A sheet-like body that cuts across rock layers and is produced when magma is injected into a fracture is called a .?
dike.
