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.
When According to the principle of cross cutting relation ships an intrusive rock body is?
When an intrusive rock body cuts across pre-existing rock layers, the Principle of Cross-Cutting Relationships states that the intrusion is younger than the rocks it cuts through. This helps geologists determine the relative ages of rock formations in the Earth's crust.
Why is an igneous intrusion younger than the rocks in which it is found?
An igneous intrusion is younger because it forms after the surrounding rocks have already solidified. Magma forces its way into the existing rock layers, and once it cools and solidifies, it is considered younger than the surrounding rocks. This relationship helps geologists determine the sequence of geological events.
What principal involves an intrusive rock body younger then the rock into which it intrudes?
The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.
Extrusive rocks which cool more rapidly than intrusive rocks generally have?
Extrusive rocks that cool more rapidly than intrusive rocks generally have a fine-grained texture with small mineral crystals. This rapid cooling prevents larger crystals from forming due to lack of time for crystal growth. Examples of such rocks include basalt and rhyolite.

According to the principle of cross-cutting relationships an intrusive rock body is?
According to the principle of cross-cutting relationships, an intrusive rock body is younger than the rocks it intrudes into. This is because the intrusion must be younger in order to squeeze into the pre-existing rocks.
Does intrusive rocks have smaller minerals than extrusive rocks?
No. Intrusive rocks have larger crystals because the magma would have taken longer to cool and solidify than extrusive magma.
Why is intrusive rock harder than a extrusive igneous rock?
The rocks are underground so intrusive rocks are under pressure so its harder.

When an intrusive rock body cuts across pre-existing rock layers, the Principle of Cross-Cutting Relationships states that the intrusion is younger than the rocks it cuts through. This helps geologists determine the relative ages of rock formations in the Earth's crust.
Do extrusive rocks have larger grains than intrusive rocks?
No, extrusive rocks typically have smaller grains than intrusive rocks. Extrusive rocks form from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. In contrast, intrusive rocks form from magma that cools slowly beneath the surface, allowing larger crystals to develop. Thus, intrusive rocks generally have larger grains compared to extrusive rocks.

An igneous intrusion is younger because it forms after the surrounding rocks have already solidified.

The principal of cross-cutting relationships involves intrusive rock body younger then the rock into which it intrudes.
Is this true or false Intrusive rocks have smaller crystals than extrusive rocks?
Generally, false. Intrusive rocks cool far more slowly than extrusive ones, so the crystals have time to grow larger.
What are extrusive rocks and intrusive rocks?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
Extrusive rocks which cool more rapidly than intrusive rocks generally have?
Extrusive rocks that cool more rapidly than intrusive rocks generally have a fine-grained texture with small mineral crystals. This rapid cooling prevents larger crystals from forming due to lack of time for crystal growth. Examples of such rocks include basalt and rhyolite.
What is the relative age relationship of faults to the rocks they cut?
Faults are younger than the rocks they cut through, as they are formed after the rock units. The offset layers or rocks along a fault help geologists determine the relative age relationship between the fault and the surrounding rocks.
