Question

during partial melting, minerals that have lower melting points melt first. * 2 points
true
false
which of the following are not intrusive igneous rock formations? * 2 points
stocks
batholiths
volcanic neck
sills

Explanation:

For the first question: During partial melting, minerals with lower melting points do melt first. This is a fundamental concept in geology related to the behavior of rocks and minerals under heat.
For the second question: Intrusive igneous rock formations are formed when magma cools and solidifies below the Earth's surface. Stocks, batholiths, and sills are all intrusive. A volcanic neck is a remnant of a volcanic pipe (where magma rose to the surface in a volcano). After the softer surrounding rock erodes away, the harder volcanic neck (solidified magma in the pipe) remains. So it is not an intrusive formation in the traditional sense as it was connected to surface - level volcanic activity.

Answer:

First question: True
Second question: volcanic neck
