Answer
The crust is the Earth layer most similar in thickness to the atmosphere.
Solution
The Earth's atmosphere is relatively thin compared to its internal layers, with most of its mass contained within the first 100 kilometers above the surface. When comparing this to the Earth's internal layers:
- **Crust:** Ranges from about 5 to 70 kilometers in thickness, varying between continental and oceanic regions.
- **Mantle:** Extends to about 2,900 kilometers.
- **Outer Core:** Approximately 2,200 kilometers thick.
- **Inner Core:** About 1,200 kilometers in radius.
Among these layers, the **crust** is the closest in thickness to the Earth's atmosphere.
**Answer:** Crust

Simplify this solution The Deep Dive
The crust is the layer of Earth most similar in thickness to that of the atmosphere. While the atmosphere varies in thickness depending on altitude, the Earth's crust ranges from about 5 to 70 kilometers thick, which is quite comparable to the atmospheric layer that commonly reaches around 10 kilometers before gradually fading into space. When thinking of the atmosphere and crust together, imagine the crust as a thin skin on a giant fruit. Just like a grapefruit skin is relatively thin compared to the massive fruit inside, the crust is thin when compared to the depths of the mantle and core beneath it!
