question 8 options:

form a new theory.

get the correct results.

obtain consistent data.

prove their hypothesis.

obtain consistent data.

Explanation:

obtain consistent data.

Explanation:

Data are documented observations or results of investigations and measurements. The availability of data offers opportunities for obtaining information. The data can be obtained by perception through the senses (for example observation) or by performing a measurement process.

Consistent are determinants in an investigation, because without them or with incorrect data, research and investigation are bound to fail, without the possibility of obtaining concrete and positive results. For this reason, it is important that investigators would repeat the same investigation several times, so they will be sure that they have collected consistent data.

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
