Annotation can be:
The table below demonstrates this process using a geography textbook excerpt (Press 2004):

|"The shape of metamorphic P-T paths provides insight into the manner in which these rocks are metamorphosed. In convergent margin settings, P-T paths indicate rapid subduction of rocks and sediments to sites with high pressures and relatively low temperatures. In settings where subduction leads to continental collision, rocks are pushed down to depths where pressure and temperature are both high. In both settings, the P-T paths form loops. These loops show that after the rocks experienced the maximum pressures and temperatures, they were pushed back up to shallow depths."||
Shape of P-T paths tells us about the conditions of metamorphosis:Convergent margin settings: rocks are subducted to depths with high temperature and low pressure- Continental collision settings: rocks are subducte to depths with high temperature and high pressure.
- Continental collision settings: rocks are subducted to depths with high temperature and high pressure
In both cases, the P-T paths form loops, showing that the rocks were pushed back up.
P-T paths show conditions
P-T paths loop
Shape of P-T paths reveals subduction site depths, temps, pressure
P-T paths loop in both settings
Yes, it can, but that time isn’t lost—it’s invested.
Spending the time to annotate on the front end does two important things:
One last tip: Try separating the reading and annotating processes! Quickly read through a section of the text first, then go back and annotate.
