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.
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.
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.

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 law states If there is a fracture or intrusive feature seen in rock strata it is younger than the rock strata?
The law that states that if there is a fracture or intrusive feature seen in rock strata, it is younger than the surrounding rock strata is known as the Law of Cross-Cutting Relationships. This principle is a fundamental concept in geology and stratigraphy, indicating that geological features like faults or igneous intrusions that cut through other rocks must be younger than the rocks they disrupt. This helps geologists determine the relative ages of rock formations and their geological history.
