A simple information ; s sub level is in any energy level,

p sub level is in any energy level beginning from the 2nd energy level,

d sub level appears ≥ 3rd energy level

f sub level appears in 4th energy level and over.

Hope it helps!

Lab: Plate Boundaries and Movement Lab Report.
Nastasia [14]

A Plate Boundaries and Movement Lab Report is a report that shows the records of all the data relating to the movement of Plate Boundaries and their movements.

<h3>What are Plates in this context?</h3>

A tectonic plate is also described or referred to as a Lithosperic Plate. In Geography, it is described as a slab of rock that is not shaped regularly.

In most cases, it comprises continental and oceanic lithosphere.

<h3>Why is it crucial to record the movement of plates and their boundaries?</h3>

Plate Boundaries and their movement are largely linked to volcanic activities and earthquakes. This means that they can be used to predict when any of the above-mentioned events may happen.
