Answer
$\color{blue}Requires$ : Comparison between height of the atmosphere and thickness of the geosphere.
Work Step by Step
The $\underline{atmosphere}$ is a very thin layer compared to the geosphere.
The thickness of the geosphere from the surface to Earth’s core is about $\color{Orange}6400 km (4000 mi)$
whereas the thickness of atmosphere is roughly $\color{orange}160 km (100 mi)$.
The $\boxed{Geosphere}$ is the largest of Earth’s four spheres.
