The document explains plate tectonics, detailing the lithosphere's composition and the differences between continental and oceanic crust. It describes the constant motion of tectonic plates, their varying movement rates, and the geological processes resulting from their interactions, such as earthquakes and volcanoes. Additionally, it mentions the triangulation method for locating earthquake epicenters and includes a materials list for a specific assignment.

2. What is Plate Tectonics?
Lithosphere- consist of crust and the upper
portion of mantle
2 Types of Crust:
1. Continental Crust
2. Oceanic Crust
-Continental crust is thicker but less dense
than the oceanic crust.
Continental crust floats higher than the
oceanic

4. Plate Tectonics- theory which
suggest that the lithosphere is said
to be in constant but slow motion.
Ex. Arctic Ridge-slowest rate(less
than 2.5 cm/yr)
East Pacific Rise-fastest rate( more
than 15 cm/yr)

5. Map of Plate boundaries

6. Triangulation Method-
locating the epicenter of an
earthquake with the use of
time intervals between the
arrivals of P and S waves
from three seismic stations.

7. Plates- are large pieces of
the upper few hundred
kilometers of Earth that
move as a single unit as it
floats above the mantle.

8. -these plates are in constant
motion.
-as they interact along their
margins, important geological
processes takes place such as the
formation of mountain belts,
earthquakes, and volcanoes.
