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.

Answer: Maybe the second one
Explanation:
Approximately 69% of earth's water is in the form of glacial ice.
Answer:
Auxiliary data from existing landcover charts, aerial photos, photography, or AVHRR can also be used in conjunction with field visits to improve map precision predictions. This improvement in precision is achieved by the use of an improved prognosis widely used in polling surveys.
Explanation:
With no additional problems in the research methodology without any unnecessary field visits, basically major increases in performance can be achieved. The first and only additional cost of obtaining the auxiliary data is incurred. The time of loss could be used with the random sample or systematic selection when the intermediate process is available throughout the region defined by the map of the land use/cover.
