Alright, good morning everybody. My name is Sergio and today I'm going to rediscuss our second lesson and the final coverage for our first longest tomorrow, the tech talk of the day. So I already skipped the preliminaries part of the Scott of the Chase so that we're going to focus on the lesson, right?
So let's recall first the seven continents according to their landmass from the largest down to the smallest. Let's start with the orange continent, so we call that Asia. Then the second greatest continent is the one in yellow, which is Africa. The third largest continent is light green, that is North America.
The fourth largest continent is dark green, just below North America, so that's South America. Then the fifth largest continent, believe it or not, that's the one at the bottom in color blue, that's Antarctica. The sixth largest continent is the one in color red, just beside Asia and above Africa, we call that Europe.
And finally, the smallest continent out of all of them is also considered a country, which is Australia. You may remember that last week, Friday, we had our very first performance task because as you can see here from the map, this one exceeds the number of continents and even the oceans. What I'm trying to say is, there are parts here where it's not exclusively continent, nor is it exclusively ocean. Instead, these are fragments of continents and oceans, and we call this as tectonic plates. Okay, so during your very first performance task, I asked you to mark the active volcanoes with red triangles, earthquake epicenters with black dots, and major mountain belts with gray triangles based from the maps that I gave you.
Because these three geological features and natural disasters, these were the basis of scientists in dividing the crust into several tectonics. As you may recall, red triangles constitute the active volcanoes. The purple dots here and several other colors as well at the center, they comprise of the earthquake epicenters. And the brown streaks here, they are the major mountain belts.
There are a total of 15 tectonic plates but we're going to only discuss the seven. So I want you to identify the major lithospheric plates from largest to smallest. The largest happens to be Pacific and Pacific happens to be the yellow plate, the one on the left. North American plate is the one that's color brown. Eurasian plate.
Eurasian plate is a combination of Europe and Asia, that's right, it's Eurasia and that's color green. By the way, the green plate, the one at the left beside North American and above in the Australian, that's also part of the Eurasian tectonic plate. Okay, next, Africa is color orange just below the Eurasian plate. Next is Antarctic and that's here, combination of blue and gray colors. And then number six is Indo-Australian beside the Pacific plate.
Indo-Australian is because it is a combination of the country Indonesia and the continent Australia. So it's Indo-Australian. And finally, number seven is South America.
It's just below North America. So that's why South America is color purple. Okay, so those are the major.
They display plates from largest to smallest. One, Pacific Yellow. Two, North American Brown. Three, Eurasian, combination of Europe and Asia, color green.
Four, African, color orange. Five, Antarctic, the one at the very bottom, combination of blue and gray. For six, Indo-Australian, combination of Indonesia and Australian, just beside the Pacific plate. And number seven is South American Color Purple just below the North American.
Okay, so let's discuss where are the active volcanoes, earthquake epicenters, and major mountain belts mostly located. So when you combine at least the two maps for the locations of active volcanoes and earthquake epicenters, this is where you will get. And as you notice, most of them are found at the edges of the tectonic plates.
So the first major location where there are mosica and sotricota plate boundaries, otherwise known as tectonic plate edges. Now the second major location where the two natural disasters are mostly located is here, the one that I already marked with a red boundary and we call that the Pacific Ring of Fire, formerly known as the Serpong Pacific Belt. This is the region where most active earthquakes and volcanoes are found.
Okay, so to recap the two major locations where earthquake epicenters and active volcanoes are mostly located are first the plate boundaries of the tectonic plate edges and the other one is here. B, pacific ring of fire, the region of most active earthquakes and volcanoes. Now let's extract the significance of mapping the locations of active volcanoes, earthquake epicenters, and major mountain belts.
So I only thought of three importance or significance. There may be more but let's condense only into three. So the first picture on the top, so you see an adult woman preparing something that's because mapping the locations of such geological features in natural disasters is very important for disaster preparedness and public safety.
Of course, if you know where you're going, or location of where I live. It's a site of a earthquake epicenter near a volcano. Therefore, when time arises for those disasters to become active, then you have time to prepare. Now, I know that most of them, most of natural disasters are very depicted as negative, but we can also extract something positive from them. So the second one is environmental conservation and resource management.
So this is specific for active volcanoes and major mountain belts because both of them are landforms and we can get minerals, which are natural resources as well, and especially rocks, which we can use when it comes to stone masonry architecture. And speaking of architecture, the last major significance of being aware of such geological features and natural disasters is for urban planning and infrastructure development. Alright, and basically that's it for our second lesson.
It's very quick compared to the first one. So that means we will have our first... very long test tomorrow that will cover the Earth's lithosphere, the Earth's crust, and our current pleasant-nearly, the ectonics. Alright, so good luck, devote your time to study, and see you tomorrow. Goodbye!
