A. Drilling down and bringing up samples to study
B. Comparing the composition of the crust to other bodies in the
solar system
C. Using remote sensing techniques in the ocean
D. Shooting seismic waves into the planet and seeing how they travel
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.
