their relative densities
Explanation:
The relative densities of the earth's materials can be inferred by the arrangement of the earth layers.
Compositionally, the earth is made up of three distinct layers; core, mantle and the crust.
- The crust is the thin outermost layer of the earth.
- The mantle straddles the zone between the core and crust.
- The core is the innermost layer of the earth.
During the formation of the earth, materials differentiated into different layers based on density.
The densest materials settled in the core and they are made up of iron and nickel metals.
The lightest materials of silicate affinity partitioned to the crust.
The mantle contained materials whose density straddles between the crust and core.

<span>A greater demand for labour in developed markets caused large amounts of migration from the Caribbean Islands. A chance to have constant steady income elsewhere created a desire to leave in order to support family when jobs were scarce in their own Islands.</span>
1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.
Answer:
Their months are based on observations of the lunar cycle, with intercalation being used to bring them into general agreement with the solar year. ... Synodic months are 29 or 30 days in length, making a lunar year of 12 months about 11 days shorter than a solar year.
