8. The Ring of Fire is
one of the most
geologically active
areas on Earth and
a site for frequent
earthquakes and
powerful volcanic
eruptions.
Editor's Notes
A volcano with accounts of eruption documented within 10,000 years (2 words)
Group of islands
Hot molten rocks formed during volcanic activity
A big body of land on the globe
A mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor and gas is being or have been erupted from the earth's crust
Layer of the Earth where magma is formed
Solid part of the Earth where volcanoes, mountain, including soils are found
Build up around the vent which comes out during volcanic eruption
The activity you had plays a vital role in laying the foundations of Plate tectonics. Land features made by these movements create fascinating scenery in the country such as Mayon Volcano in Legaspi, Albay.
There are about 300 volcanoes in the Philippines. Twenty-two (22) of which are active while the greater percentage are dormant.
Mayon Volcano…
Last eruption of Mayon Volcano – June 12, 2023
SAY: Our Earth has four layers consisting of different materials, namely, crust, mantle, inner, and outer core. ..
Q: WHAT DO YOU CALL THE PART/LAYER OF THE EARTH WHERE CRUST AND UPPER MANTLE IS LOCATED? LITHOSPHERE
SAY AFTER THE ACTIVITY..What did you observe in the previous activity? Did you find the earthquake epicenters, volcanoes, and mountain ranges close to each other if not situated in the same locations? Have you ever wondered how this could be possible?
Remember that plates are in constant motion. As they interact along their margins, important geologic processes take places, such as the formation of major
mountain ranges, active volcanoes, and earthquake epicenters. It means to say that, where there are earthquakes, crusts can either meet or move apart and form
mountains and volcanoes.
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. That’s why the name derived from itself and eventually known as PLATE TECTONICS…
The arrows show the direction of the plate movement and the other lines are the fault lines…
You will notice in the above figure that there are seven relatively large plates and several smaller ones, including the Philippine plate? Can you remember all their
names? Please do the activity below to see how these plates relate to earthquakes,volcanism, and mountain formation.
SAY : OBSERVE THE MAP OF THE WORLD…DO YOU WONDER HOW THOSE CONTINENTS MOVE AWAY FROM EACH OTHER…Plate movements may result in earthquakes. Earthquakes may happen anytime, either on land or underwater. Earthquakes on land can be caused either by tectonic plates movement or volcanic eruptions. Earthquakes under the sea can cause a tsunami. ..let us know more about one of the most devastating natural phenomena that affects almost everything …from properties to livelihood…
Our country, the Philippines, is situated in a place where Plate Tectonics is very evident the Ring of Fire. It is a long chain of volcanoes and other tectonically.. active structures that surround the Pacific Ocean. The Ring of Fire is one of the most geologically active areas on Earth and a site for frequent earthquakes and powerful volcanic eruptions.
