You think probable to the Earth crust.
The Earth crust has a thickness of 5-70 km.
Crust
The thinnest layer of the Earth's shell is the crust, which is divided into the oceanic crust and the continental crust. The oceanic crust is thinner, ranging from 5-10 kilometers thick, while the continental crust is thicker, averaging around 30-50 kilometers thick.
The Earth's first layer, known as the crust, varies in thickness depending on whether it's continental or oceanic. Continental crust averages about 30-50 kilometers (19-31 miles) thick, while oceanic crust is generally around 5-10 kilometers (3-6 miles) thick. This layer is the outermost part of the Earth, sitting above the mantle.
The continental crust is about 25 to 70 kilometers thick. The average is about 50 kilometers.
Earth's thinnest layer is the crust, which is found on the outermost part of the planet. It is divided into tectonic plates that float on the semi-fluid mantle below. The crust is thinnest under the ocean, averaging around 5-10 kilometers thick, while being thicker under continents, averaging around 30-50 kilometers thick.
I think the answer is thin; the crust is between 3 and 30 miles thick; less than 1% of the diameter of the Earth.
There's no specific answer because it discontinued
The mesosphere is the layer of Earth's atmosphere located between the stratosphere and the thermosphere. It extends from about 31 to 53 miles (50 to 85 kilometers) above the Earth's surface.
The thinnest Earth sphere is the Earth's crust, which is the outermost solid layer of Earth. The crust is thinnest beneath the oceans, where it can be less than 5 kilometers (3 miles) thick, compared to the continental crust, which averages around 30 kilometers (18 miles) in thickness.
The Earth's crust varies in thickness, averaging around 20-30 kilometers (12-18 miles) under continents and about 5-10 kilometers (3-6 miles) under oceans. However, there are regions where the crust can be much thicker or thinner due to geological activity.
The ozone layer is located approximately 9 to 18 miles (15 to 30 kilometers) above the Earth's surface in the stratosphere.
The ozone layer is the thinnest layer of the Earth's atmosphere, located within the stratosphere at an altitude of about 10 to 50 kilometers above the Earth's surface. Its thickness can vary, but on average, it is only a few millimeters thick.
