Answer:
The intrusion of I1 or I2 is the youngest event. Without more information, we cannot know which igneous rock is youngest.
Explanation:
The information contained in the question above is not sufficient to determine which of the two igneous rock intrusions is the youngest event, although we can say that it was one of the two.
Even in the absence of a complete answer, it is worth describing what an ignea rock is. Ignal rocks can also be called magmatic rocks and are characterized as a terrestrial rock that originated from the solidification of magma, without having previously undergone a process of sedimentation or metamorphism. As you may already know, magma can solidify and cool on the earth's surface, or inside the earth, giving rise to extrusive and intrusive igneous rocks.
Thew sun is very hot it sends more than amillion beams of heat toward land and by the time it hits us "the land" the ground gets hot which travles to the ground under waters now places like the ocean that have waters deeper than a thousand miles will not get as hot if any where near as hot as the water closer to land because the sun sadly does not travle that deep into the ground
