The Earth's layers are commonly divided into two main parts: the crust and the mantle. The crust is the outermost layer, while the mantle lies beneath it, extending to a depth of about 2,900 kilometers (1,800 miles). Together, these layers play a critical role in the structure and dynamics of our planet.

What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
What is the densest composional layer that makes up one-third of earths mass?
The densest compositional layer of the Earth that makes up about one-third of its mass is the core. The core is primarily composed of iron and nickel, and it consists of two parts: the solid inner core and the liquid outer core. This layer is responsible for generating the Earth's magnetic field through the movement of molten iron in the outer core.
Which two minor layers are parts of a main layer?
The Ionosphere and the Exosphere (minor layers) are parts of the Thermosphere (major layer).The ionosphere is part of the theremosphere.
Which layer of the Earth is composed of iron and nickel and has two main parts called the outer and the inner?
The layer of the Earth that is composed of iron and nickel is the core. It has two main parts: the outer core, which is liquid and responsible for generating the Earth's magnetic field, and the inner core, which is solid due to the immense pressure at that depth.
What is the meaning of mantle?
The mantle can refer to a few different things: In geology, the mantle is the layer of rock between the Earth's crust and core. In clothing, a mantle is a loose sleeveless cloak or shawl worn over other garments. In leadership, the mantle can symbolize the responsibility or authority passed from one individual to another.
Is the outermost layer?
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.

What layer of the atmosphere has two layer parts?
The stratosphere is the layer of the atmosphere that contains two distinct parts: the lower stratosphere and the upper stratosphere. The stratopause boundary separates these two regions, with the lower stratosphere characterized by a temperature inversion and the upper stratosphere containing the ozone layer.
What layer has two parts?
ionosphere
The atmosphere and lithosphere are parts of earths?
The atmosphere is the layer of gases surrounding the Earth, while the lithosphere is the solid outer layer of the Earth consisting of the crust and upper mantle. These two components interact and influence each other through processes like weathering and erosion.

What is the name of upper suface of the earth?
The lithosphere, it consists of two parts, a thin outside layer of solid rock called the crust and the rigid upper part of the mantle.
