The method that scientists use to determine the composition of Earth's layers is comparing the composition of the crust to other bodies in the solarsystem. The correct option is B.
Based on composition, there are three divisions: core, mantle, and crust. Oceanic and continentalcrust, which makes up less than 1% of the Earth's total mass, typically contains more felsicrock.
Approximately 68 percent of the mass of the Earth is in the heated mantle. The core's primary metal composition is iron.
The majority of the rocks that make up the Earth's mantle are silicates, a large class of substances with a common silicon and oxygen structure.
The core is almost entirely comprised of metal, notably iron and nickel, in contrast to the crust and mantle, which are rich in minerals.
Scientists compare the composition of the crust to that of other worlds in the solarsystem to ascertain the composition of the Earth's layers.
Thus, the correct option is B.

solar system
Explanation: I took the quiz
B) These advancements do not contribute to the greenhouse effect.
C) These advancements use cleaner fuels thereby reducing pollution.
D) These advancements are very expensive and not available to everyone.
Answer:
The correct option is D) These advancements are very expensive and not available to everyone.
Explanation:
Consider the statement A. It states that the new technological advances uses renewable sources of energy. This is a positive aspect as the energy can be renewed and replaced. The corn from which this energy is derived can be produced over and over again. Hence, this is a positive aspect, not a negative aspect.
Consider statement B. This statement tells us that the new technological advances will not result in warming the Earth's atmosphere by greenhouse effect. Hence, it is a positive aspect.
Consider statement C. It states that the new technological advances will lead to lesser pollution. Hence, it is a positive aspect.
Now, consider statement D. It is a drawback because technological advances are too expensive to be used by many people. Hence, it is a negative aspect.
Answer:
D) These advancements are very expensive and not available to everyone.
Explanation:
Answer:
If a volume of air contains its maximum amount of water vapor and the temperature is ... millennia is controlled by non-condensable gases, mainly carbon dioxide, CO2, with smaller contributions from methane, CH4, nitrous oxide, ... If the amount of solar warming decreases, then the temperature of the Earth would decrease.
Explanation:
B. Location near headwaters
C. Lack of meanders
D. A low stream gradient
i think i would say (D) A low stream gradient
Answer:
Habitat:
Habitat may be defined as the particular area occupied by the organism. Habitat involves the physical activity performed by the organism in its area. Habitat only reflects the living place of the organism. Habitat explains where the species live in the ecosystem.
Niche:
Niche may be defined as the role of the individual organism in its ecosystem. The function or the physiological activity of the organism in the area describes the niche. The association of the organism with the biotic and abiotic component to obtain food is included in niche. Niches explains the way by which organism live in an ecosystem.
