The rock cycle showing how rocks transform under heat, pressure, and weathering.

The image provided illustrates the rock cycle, which is a fundamental concept in geology. The rock cycle describes the continuous process by which rocks are transformed from one type to another through various geological processes. Below, I will explain the solution and fill in the missing labels in the diagram.

Key Components of the Rock Cycle

1. Igneous Rocks: Formed from the cooling and solidification of magma (below Earth's surface) or lava (on Earth's surface).
2. Sedimentary Rocks: Formed from the compaction and cementation of sediments (e.g., sand, mud, shells) that have been deposited by wind, water, or ice.
3. Metamorphic Rocks: Formed when existing rocks are subjected to high temperatures and pressures, causing them to change their mineral composition or texture without melting.

Diagram Analysis and Labeling

Let’s analyze the diagram step by step and determine the appropriate labels for the blue boxes and green circles.

#### 1. Magma from Molten Crust and Mantle
- Blue Box 1 (Left Side): This represents the igneous rock formed when magma cools and solidifies beneath the Earth's surface. This is called an intrusive igneous rock (e.g., granite).
- Green Circle 1 (Top Left): This represents the igneous rock formed when lava cools and solidifies on the Earth's surface. This is called an extrusive igneous rock (e.g., basalt).

#### 2. Weathering, Erosion, and Deposition
- Green Circles 2 and 3 (Right Side): These represent the sediments formed through the weathering and erosion of existing rocks. These sediments are transported by wind, water, or ice and eventually deposited in layers.

#### 3. Sedimentary Rock Formation
- Blue Box 2 (Bottom Right): This represents the sedimentary rock formed from the compaction and cementation of sediments. Examples include sandstone, limestone, and shale.

#### 4. Metamorphism
- Blue Box 3 (Center): This represents the metamorphic rock formed when existing rocks (igneous, sedimentary, or other metamorphic rocks) are subjected to high temperatures and pressures deep within the Earth. Examples include marble, slate, and gneiss.

#### 5. Melting and Recycle
- Green Circle 4 (Bottom Left): This represents the melted rock (magma) that forms when rocks are subjected to extreme heat, often due to tectonic activity or mantle convection. This magma can rise to the surface or cool beneath the crust, restarting the cycle.

Final Labels

Here are the labels for the blue boxes and green circles:

1. Blue Box 1 (Left Side): Intrusive Igneous Rock (e.g., Granite)
2. Green Circle 1 (Top Left): Extrusive Igneous Rock (e.g., Basalt)
3. Blue Box 2 (Bottom Right): Sedimentary Rock (e.g., Sandstone, Limestone)
4. Blue Box 3 (Center): Metamorphic Rock (e.g., Marble, Slate)
5. Green Circle 4 (Bottom Left): Melted Rock (Magma)

Explanation

The rock cycle is a continuous process where rocks are transformed from one type to another:
- Igneous rocks form from the cooling of magma/lava.
- Sedimentary rocks form from the deposition and compaction of sediments.
- Metamorphic rocks form from the transformation of existing rocks under high temperature and pressure.
- All types of rocks can be subjected to melting, starting the cycle anew.
