Compositional layers are determined by their components, while mechanical layers are determined by their physical properties.

“The Earth’s lithosphere is thinner than its asthenosphere”, the statement correctly compares the thicknesses of Earth’s layers

Option D


The outermost parts of the Earth composed of crust and a part of the upper mantle is termed as lithosphere. And asthenosphere is positioned below lithosphere. The bottom layer of lithosphere has the parts of the upper crust.

So the highly viscous and ductile region in the remaining part of the upper crust forms the asthenosphere below the lithosphere. The upper crust in the lithosphere region contain elastic properties while the upper crust in the asthenosphere is ductile in nature. Thus the statement that lithosphere is thinner than asthenosphere is true as it is located at the surface.

The top layer is exosphere. The fourth is the Thermosphere. The middle layer is the mesophere. The second layer is the Stratospere. the lowest layer is the troposphere


The ozone layer


The ozone layer is a gaseous cover found in the stratosphere. It is extremely important for life on Earth because it absorbs ultraviolet gases emitted by the sun. In the 1980s, scientists were able to prove that the continuous emission of gases by industry destroyed the stratosphere's ozone molecules. In order to prevent the collapse of the ozone layer, the international community signed in 1987 the Montreal Protocol, a document aimed at reducing the emission of gases that caused its destruction.

The correct answer is A


The correct answer is A. 110GPa


Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.

In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.



earth's lithosphere is thinner than is asthenosphere

All the answers are.

Explanation: 1 clouds and possible precipitation

2 each grid point on a three-dimensional get

3 it produces uneven heating of earths surface by the sun

4 C a warm surface current flows along the east coast of the United States and a cold water surface current flows along the West Coast of the United States

5 plate tectonics

6 wet soil absorbs heat more slowly, due to waters high heat capacity

7 top layer: exosphere, fourth layer:thermosphere, middle layer:mesosphere, second layer: stratosphere, lowest layer: troposphere

8 physics that describes how air moves and heat and moisture are exchanged.

I just took the test and these are the correct answers, I hope this helped you.

The three layers of Earth contribute to the uniqueness of this planet. The crust, mantle, and

core are all distinctive, varying in composition, temperature, pressure, and state of matter.

From a solid metal center, surrounded by a liquid core, to a sea of soft putty-like rock mantle,

topped with a solid, rock crust, there is no planet like Earth in the entire solar system.

hope this helps
