the crust because that is the layer we live on so scientists can study it more thourouly
The inner core.
Seismic Tomography is the most popular technique used to find the Earth's sub-surface characteristics.
Scientists believe that the Earth's inner core is most likely made of solid metals, primarily iron and nickel. This is supported by seismic wave data and studies on the Earth's magnetic field.
The 3 layers of the earth are the crus,mantle and the core. Crust-is the outer most layer of the earth Mantle-is the center layer of the earth Core-is the inner most layer of the earth
Most organisms never became fossils
Troposphere.Another AnswerThere is another layer that most atmospheric scientists and meteorologists may not agree with, but most biologists would, and that is the biosphere. It is the part of the atmosphere that participates in the respiration process of plants and animals, and it contributes to the earth's atmosphere in a subtle, yet dramatic, way.
The layer that affects the earth's surface is ozone. Ozone is a layer of importance.
the outer most layer of earth is CRUST
Virtually all of earths aluminum ore is in the top layer of the earth, the crust.
Most weather phenomena occur in the troposphere, which is the lowest layer of the Earth's atmosphere, extending up to about 10-15 kilometers from the Earth's surface. This layer is where clouds, precipitation, and most of the Earth's weather systems are located.
The layer of the Earth that weighs the most is the mantle. The mantle is a thick layer of solid rock located between the Earth's crust and core. It makes up about 84% of the Earth's total volume and contains a large portion of the Earth's mass.
