2. What is Plate Tectonics?
The plates move very slowly but constantly, and this movement is called
tectonics; thus the theory of moving lithospheric plates is called plate
tectonics.
4. What are the two layers of the
lithosphere?
Crust and Upper Mantle
5.
6. . Plate boundaries are divided into such manner in terms of
their boundaries
7. Questions
What do you call the rigid outer part of the earth? What
are its layers?
- Lithosphere, Upper Mantle)
Do you believe that these plates are moving?
Yes
8. Questions
Based on the video presented, what is tectonic?
-Tectonic refers to the movement of plates
How will you compare continental crust and oceanic crust?
Oceanic crust is generally composed of dark-colored rocks
called basalt and gabbro. It is thinner and denser than
continental crust, which is made of light-colored rocks called
andesite and granite. The low density of continental crust
causes it to “float” high atop the viscous mantle, forming dry
land.

11. What are the different major plates of our planet?
Pacific Plate, North American Plate, Eurasian Plate, African
Plate, Antarctic Plate, Antarctic Plate, Indo-Australia Plate
What do you call that rigid outer layer of the earth where the crust
and mantle is located?
Lithosphere

14. What do you call the waves released during earthquake?
What are its types?
How will you compare the movement of the waves that travels in the
interior layer of the earth?

Do you still remember your discussions during your Grades 8 and 9 about volcanoes and earthquakes? You need to recall important words related to volcanoes and earthquakes that will be used in this module. Below is a vocabulary word list with missing letters. Read the definition on the left side to complete each word on the right side. Write your answers on a separate sheet of paper.
Our Earth has four layers consisting of different materials, namely, crust, mantle, inner, and outer core. For this module, we will focus on the lithosphere which is composed of the crust and the upper mantle.
The lithosphere is said to be in constant but very slow motion. These motions are not the same everywhere. This movement of the lithosphere is called tectonics.
. According to the Plate Tectonics Theory, the entire lithosphere of the Earth is broken into numerous segments called plates (see Figure 1). The arrows show the direction of the plate movement and the other lines are the fault lines.
