D: The D" layer of Earth is about 3% of Earth's mass, is 125 to 188 miles (200 to 300 kilometers) thick and covers about 4% of the mantle-crust mass. This layer, in terms of whether it is part of the lower mantle or an independent layer is still somewhat unclear.

Inside the Earth; Printout: Label the Inside of the Earth; The Earth is made of many different and distinct layers. The deeper layers ... The lithosphere is defined as the crust and the upper mantle, a rigid layer about 100-200 km thick. The Mohorovicic discontinuity is the separation between the crust and the upper mantle.

Exploring the Earth's Core ... This study of one layer maps out an ancient network of sandy stream channels, much like the modern channels of the Laramie River, right. Such buried channels can yield oil or gas easily if seismic reflection work can pinpoint their locations.

This layer around the earth is a colorless, odorless, tasteless 'sea' of gases, water and fine dust. The atmosphere is made up of different layers with different qualities. It consists of 78% nitrogen, 21% oxygen, 0,93% argon, 0,03% carbon dioxide and 0,04% of other gases.
