The thickest part of the Earth is called the mantle.
Tectonic plates are not below earth's surface; they would be considered "earth's surface." They are known as "crust" and can be either oceanic or continental. These plates and the upper mantle (known as the lithosphere) float on top of the asthenosphere. They can vary from between40-200 km in thickness.
4,000m.thick
It's not four layers , Five layers.The layersof theatmosphere- the Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
Standing 850 feet, above the plains with a circumference of five miles, Stone Mountain is the largest exposed mound of granite in the world.
The oceanic crust.
It is many hundreds of miles from mount Everest to the sea but if there was a "sea level" under the mountain peak it would be about five miles below the highest point. (The Earth really is fairly smooth if you look at it from space- the thickness of the layer of clear varnish on the surface of a one foot diameter world globe is greater than the breathable atmosphere's thickness)
Layer Five was created in 1997.
Layer Five ended in 1999.
That depends on what you mean by the "first" layer. The lowest layer (the first off the ground) is the Troposphere. The highest layer (the first coming in from space) is the Exosphere.
There are five layers of atmosphere that protect the earth from the sun and other space debris. The thickest layers are located near the surface and thins out with height until it merges with the bare space. The five surface from the surface to earth; troposphere, stratosphere, mesosphere, thermosphere , and exosphere respectively. The Stratosphere is where the ozone layer is formed with just about 3 millimeters thick and 20 km above the earth surface.
No. The ozone layer sits in the Earth's stratosphere, 10 to 50 kilometers or 6 to 31 miles from the Earth's surface.

Earth contains a five layer atmosphere. It is due to gravity.
