To determine which statement describes one or both formations accurately, let's break down the terms used:
- **Extrusion**: This refers to igneous rock that forms from lava that has cooled and solidified on the Earth's surface.
- **Intrusion**: This refers to igneous rock that forms from magma that cools and solidifies inside the Earth's crust.
- **Faults**: These are fractures in the Earth's crust where blocks of rock have moved past each other.
- **Igneous rock**: This type of rock forms through the solidification of molten material, which can be either magma (intrusions) or lava (extrusions).
Given this information, here's how we can analyze the statements:
A. Formation 2 is an extrusion.
B. Formation 1 is an intrusion.
C. Formations 1 and 2 are faults.
D. Formations 1 and 2 are igneous rock.
Without seeing the actual diagram, we can't definitively determine the correct answer. If Formation 1 appears to be below the surface and represents solidified magma, it would be an intrusion (making B correct). If Formation 2 is above the surface and represents solidified lava, it would be an extrusion (making A correct). If the formations do not represent faults nor solely igneous rock, then C and D would be incorrect.
In most cases, igneous rock formations consist of intrusions and extrusions, so if both formations are igneous, D may also be a possibility.
Choose B if Formation 1 is under the surface (intrusion). Choose A if Formation 2 is above ground (extrusion). Without visualization, I'm unable to determine which statements are accurate; however, those are the ways you can analyze each statement according to the definitions.
