A radiometric age for a mineral crystal inside an igneous rock measures the amount of time that has passed since the atoms within the crystal were part of a body of molten magma.
<h3>What is igneous rock? </h3>
Igneous rocks create when lava colds and crystallizes, either on the boundary of the Earth or heavy inside the crust.
Because of the high heat present underneath, all magma forms in the lower crust or upper mantle.
A mineral crystal's radiometric age in an igneous rock indicates how long it has been since the atoms within the crystal were part of a molten magma body.

Answer:
Scalar quantity
Explanation:
Scalar quantities give a magnitude, while vector quantities give a magnitude and a direction. The answer will be a measurement that does not change, regardless of the direction of action. Displacement is a measure of length in a given direction; distance is the scalar version of displacement. hence length is scalar quantity
Answer:
The Milankovitch cycles describe the change in eccentricity because of changes in the orientation of Earth relative to the Sun.
