Answer:
The earth is made out of layers that separate according to their d<u>ensities.</u>
The density of each layer is affected by the <u>composition</u> of the material and the amount of <u>pressure </u>
it is under.
The thinnest and least dense layer is known as the <u>Crust.</u>
The layer under the most pressure is known as the <u>core.</u>
Such high amounts of pressure cause this layer to remain in a <u>Solid State of matter</u> even though the nickel and iron are at such a high temperature.
On the other hand, the outer core remains in a molten state of matter even though it is made out of the same materials as the inner core since there is not enough <u>pressure </u>to change it to a solid.
Explanation:
The above question now updated with the missing words provide information about how the compositional layers of the earth's crust are formed.
The three major determinants as already explained about how the layers have come to be are:
- Composition of Material
- Pressure on the material
- and their density
The Crust (which is the outmorst layer) comprises of more silica.
The Mantle is a combination of silica, magnesium, and iron.
The core is a combination of oxygen, nickel iron and sulphur.

''A remnant or a trace of an organism, such as a skeleton or a leaf imprint embedded and preserved in the Earth's crust, are examples of fossil evidence.''
Fossils are left overs from the living organism, both parts of them and traces by them. Fossils are used by scientists to recreate the past of the Earth, the life on it, how did they lived, how did they look, the environment, whole ecosystems...
Answer:
Impacts of transportation and communication strategy and sotance decays shows the impacts of time and distance on the spatial interaction.
Explanation:
- The time series interaction was given by David Harvey in postmodernity were he shows the phenomenon that alters the quality of relationships and was published in 1989.
- Distance decay shows the impacts of distance and states that the interaction between the two local declines as the distance between them increases. Such as seen in communication technology and the growth of urban centres in the central business district. Density, price of land, and other factors are seen.
