Answer:
The magma moves upward and erupts to form either an oceanic ridge or a hot spot volcano. At subduction zones, volatile compounds (especially water) escape from the subducting plate and lower the melting temperature of the overlying mantle rocks. This triggers melting and magma forms as a result.
Explanation:
It is false that scientists are able to determine the relative age of rocks in specific years. This is because relative age refers to how much <span>one layer is older or younger than another layer but does not indicate the rock's age in years, but perhaps in centuries at most. Scientists can, however, determine the absolute age of rocks using radiometric dating. </span>
