The Earth's crust is about 40 km thick on average. It is made up of solid rock and is divided into two types: the continental crust, which is thicker but less dense than the oceanic crust.
We live on the crust. It is the thinnest layer of rock.
The Earth's crust is the thinnest layer, ranging from about 5-70 km thick. The average density of the Earth's crust is around 2.7-3.0 g/cm³.
The mantle layer of the Earth is approximately 2,900 kilometers (1,800 miles) thick. It is located between the Earth's crust and core. The mantle is composed of solid rock that can flow slowly over long periods of time.
If continental crust were thinner than its average thickness of 40km, it would depress the mantle less than it does now. This is because less mass in the thinner crust would exert less pressure on the mantle, resulting in less depression.
The layer of the Earth that includes the surface is the crust. It is the outermost solid layer of the Earth, ranging from 5 to 70 km thick beneath the oceans and up to 100 km thick beneath the continents.

No, the oceans do not contain enough salt to cover all of the continents with a layer 50 feet thick. The average salt content in the oceans is about 3.5%, and there is not enough salt to form a layer that thick on the continents.

Ozone layer is the thick layer. It protects us from UV rays of the sun.
It is 40km because 4000m equals 4km

mantle is the thick layer before you reach the core of the earth
The thinnest layer of Earth's atmosphere is the exosphere, which extends from about 600 kilometers above sea level to about 10,000 kilometers. However, if you are referring to the layer that is approximately 12 kilometers thick, that would be the troposphere, which is the lowest layer of the atmosphere where weather occurs. The troposphere varies in thickness, being thicker at the equator and thinner at the poles, but on average, it is around 12 kilometers thick.
