Question
4 rock layers. Top: rocks composed of gray clay flakes with crystals of minerals. Middle: Rocks made of shale and skeletons of marine organisms. Bottom: Reddish brown rocks with sand-sized rock grains. Instrusive layer of magma within bottom layer.
Number the events (1-4) based on the order that they happened, with 1 being the first thing that happened and 4 being the last.
Magma cut into the red-brown rocks and solidified to form glasslike rocks.
Red-brown rocks with sand-sized rock grains were deposited horizontally.
Rocks composed of gray clay flakes with crystals of minerals were deposited horizontally.
Rocks made of shell and skeletons of marine organisms were deposited horizontally.

To determine the order of events based on the rock layers described, we must consider the principles of sedimentary rock formation and the formation of intrusive igneous rock. Here’s the correct sequence based on the information provided:
1. **Red-brown rocks with sand-sized rock grains were deposited horizontally.**
- This is likely the oldest event, as it describes the foundational layer of rock deposition.
2. **Rocks made of shell and skeletons of marine organisms were deposited horizontally.**
- This layer comes after the red-brown rocks, indicating that marine life developed and was preserved, forming the next sedimentary layer.
3. **Rocks composed of gray clay flakes with crystals of minerals were deposited horizontally.**
- This layer is above the previous layers, indicating further sedimentation after the deposition of the marine organism layer.
4. **Magma cut into the red-brown rocks and solidified to form glasslike rocks.**
- This is the final event, where magma intruded and solidified within the bottom layer of red-brown rocks, altering them.
So, the numbered order is as follows:
1. Red-brown rocks with sand-sized rock grains were deposited horizontally.
2. Rocks made of shell and skeletons of marine organisms were deposited horizontally.
3. Rocks composed of gray clay flakes with crystals of minerals were deposited horizontally.
4. Magma cut into the red-brown rocks and solidified to form glasslike rocks.
