either crust or biosphere. your choice
biosphere
The percentage of Earth's crust is less than one percentage in terms of Earth's volume. The Earth's crust is actually a thin layer.
troposphere
Called the biosphere
The relatively thin layer of Earth and its atmosphere that supports life is called the biosphere. It includes all living organisms and their interactions with each other and with the abiotic environment.
Compared to the size of the entire Earth, the crust is very thin. It makes up only about 1% of Earth's volume and is relatively thin, ranging from 5 to 70 kilometers thick beneath the continents and around 5 to 10 kilometers thick beneath the ocean basins.
I believe you're referring to the biosphere
The thin layer all life on Earth depends upon is the atmosphere. It contains the oxygen, carbon dioxide, and other gases necessary for life, and helps regulate temperature and protect living organisms from harmful radiation from the sun.
The thin layer of gases surrounding the Earth is called the atmosphere. It plays a crucial role in maintaining the right conditions for life to exist on our planet.
The thin layer of air that surrounds Earth is called the atmosphere. It is composed of various gases, predominantly nitrogen and oxygen, and plays a crucial role in regulating Earth's climate and supporting life.
If you mean, thin layer of air, or thin gaseous layer surrounding the earth then the answer is; Atmosphere. But if not, then the other thin layer of earth is; The crust, but its a solid layer.
