Question

identify the intrusions in the rock layers.

Explanation:

Step1: Recall intrusion definition

Intrusions are igneous rock bodies that form when magma cools and solidifies beneath the Earth's surface, cutting through existing rock layers.

Step2: Analyze each labeled area

• Layered rocks (D, E, F, etc.): These are sedimentary or stratified rocks, formed by deposition, not intrusion.
• J, H, K: These have non - layered, intrusive - like patterns (e.g., J has a distinct, non - stratified shape cutting through layers; H is a dike - like structure cutting through layers; K is a pluton - like body cutting through layers).
• A, G, L: A and G seem to be surface - related (like water or soil), L is a fault (a break, not an intrusion).

So the intrusions are J, H, K (or identifying the ones with intrusive features: J (pluton), H (dike), K (pluton/intrusion), etc. depending on the exact diagram interpretation, but typically J, H, K are intrusions as they cut across the layered rock structures).

Answer:

The intrusions in the rock layers are the rock bodies labeled J, H, and K (these are igneous intrusions as they cut through the pre - existing sedimentary/layered rock layers).
