Step 1:I'll solve this problem step by step, focusing on Earth's internal structure and temperature.
Step 2:: Identify Earth's Layers
Earth has several distinct layers, from the outermost to the innermost: - Crust - Mantle - Outer Core - Inner Core
Step 3:: Determine Layer Temperatures
Let's order the layers from coolest to hottest:
Step 4:
Crust: $$0 - 200 \mathrm{~{}^\circ C}
- Coolest layer - Solid rock - Thinnest layer
Step 5:
Mantle: $$200 - 1,600 \mathrm{~{}^\circ C}
- Mostly solid, but partially molten - Thick layer beneath the crust
Step 6:
Outer Core: $$4,400 - 5,700 \mathrm{~{}^\circ C}
- Liquid metal - Primarily iron and nickel
Step 7:
Inner Core: $$5,700 - 6,700 \mathrm{~{}^\circ C}
- Hottest layer - Solid due to extreme pressure - Primarily solid iron
Final Answer
1. Crust 2. Mantle 3. Outer Core 4. Inner Core
