Step 1:I'll solve this problem by carefully matching each geological term with its most appropriate definition.
Step 2:: Understand the Geological Terms
Let's first review the key characteristics of each term: • Plutons • Sills • Injection • Dikes
Step 3:: Define Plutons
Plutons are large, intrusive igneous rock bodies that form when magma cools slowly beneath the Earth's surface. They typically: - Crystallize deep underground - Are usually massive in size - Form large, coarse-grained rock formations
Step 4:: Define Sills
Sills are: - Horizontal or near-horizontal intrusive igneous rock layers - Formed when magma intrudes between existing rock layers - Parallel to the surrounding rock's bedding planes
Step 5:: Define Injection
Injection in geological terms refers to: - The process of magma or molten rock being forced into existing rock formations - A mechanism of intrusion where molten material fills spaces or cracks
Step 6:: Define Dikes
Dikes are: - Vertical or steeply inclined sheet-like igneous intrusions - Cut across existing rock layers at an angle - Often form when magma fills fractures in pre-existing rock
Final Answer
• Plutons: Large, deep underground igneous rock formations • Sills: Horizontal intrusive igneous rock layers between existing rock strata • Injection: Process of magma being forced into rock formations • Dikes: Vertical/angled sheet-like igneous intrusions cutting across rock layers
