Types of Plate Boundaries

Three types of plate boundaries


Know: the different types of Boundaries and exhibited movement.

PLATE BOUNDARIES

  • Convergent Plate
  • Divergent
  • Transform Fault

Divergent Plate

plates move apart, creating a zone of tension

Convergent Plate

moving toward each other, plates collide. Philippine plate & Eurasian plate.

Transform Fault

plates slide or grind past each other without diverging or converging. San Andreas fault bounded by North American & Pacific plate.

TRIANGULATION METHOD IN LOCATING EARTHQUAKE'S EPICENTER


Collision of Plate Boundaries

Locating the Earthquake Epicenter

* * *

© DENNIS F. ERASMO

Center of an Earthquake

Triangulation Method


Objective: Find the Epicenter of an earthquake using Triangulation Method

Materials:

  • hypothetical records of earthquake waves
  • Philippine map
  • drawing compass and ruler

Triangulation Table

Data. Computation is required!

RECORDING STATION TIME DIFFERENCE DISTANCE COMPUTED
Batangas 44.8
Puerto Princesa 32
Davao 38.4

NOTE: Time difference - difference in the arrival time of P-wave and S-wave in seconds.

Things to do in Triangulation

FOLLOW the STEPS ACCORDINGLY


  • STUDY THE DATA

    Shown is the difference between the arrival time of P-waves and S-waves.

  • COMPUTE THE DISTANCE

    Distance from the epicenter from each station using formula d=(Td/8sec)x 100km.

  • CHOOSE ONE OF THE RECORDING STATION

    Measure the computed distance on the map scale. the scale of the map in Figure 3 is 1.5 cm: 200 km.Set your compass for that computed distance

  • AGAIN, ON THE OTHER RECORDING STATION

    Center your compass, then draw a circle.

  • REPEAT STEPS 3 & 4 FOR THE REST OF THE STATIONS.

    You should get three circles that intersect or nearly intersect at a point. This intersection is the epicenter.

GUIDE QUESTIONS

Q1. Where is the epicenter of this hypothetical earthquake?


Q2. What difficulty will you encounter if you only have data from two recording stations?

Difference P & S Waves

GUIDE QUESTIONS

Q3. The distance-time graph above shows that the S-P interval is aout 10 minutes. What is the distance of the epicenter from the seismic station?


Q4. What do you think is the importance of determining the epicenter of an earthquake?

Determining the location of earthquake epicenters plays a vital role in laying the foundations of plate tectonics.

DepEd LM for Grade 10 Science, 2014

That's how!

Now you know!

Thank you!

MS Word or Google Docs? (A Poem)

MS Word or Google Docs?
(A Poem - Dennis F. Erasmo - 8/12/14 12:00 PM)
Dennis F. Erasmo (Author)

Microsoft word is an standard
Google Suite comes in.
The two are both word processor
But Google docs is online.

You can save documents online
You can access Google Suite anywhere
You can use your mobile devices
Such as iOS devices or Android phone and tablets.

Google Suite is OS independent
With just a browser and internet
You can edit and print your documents
And submit these wherever you are on Earth.

ACTIVITY # 1 – APPLYING HTML TAGS
1.       Type the document below in Notepad.
Nature Reveals
Our Physical World, respect and explore. Where water meets land, a beautiful shore. Mountains we conquer, look down in awe. If you're an artist, make sure you draw. Nature exciting, adventurously new. Much more to see than a sky that is blue. If offers so much, open your eyes. Hope of today, with every sunrise. Nature shall feed, body and soul. Some call it home, others a hole. Memories are nurtured, when nature reveals. Sharing its pleasures, amazing it feels.
2.       Apply HTML Tags by inserting them into your document.
3.       For the document title, type:
<center><strong>Nature Reveals</strong></center>
4.       Enclose the paragraph with the opening <p> tag and the closing </p> tag.
5.       Add <em><b> and </b></em> to the words “respect and explore” like this:
<em><b> respect and explore </b></em>
Do this also in “body and soul” on the paragraph. The tags will make these words bold and slanted.
6.       Save the document as nature.html on your preferred folder.
7.       View the file on your web browser.

ACTIVITY 02 – CREATING AN HTML FILE IN NOTEPAD
1.       Launch Notepad.

Lesson 01 on HTML5 AND CSS3

WEBSITE LAYOUTING IN CSS3 WITH HTML5

Creating Divisions using HTML5 Semantics
a.  Create New Folder in Documents with your Name+Site+Project.
b.      Inside your Site Project folder, create two additional folder and name it img & css respectively.
c.       Collect at least 1 logo (science, etc), 1 photo and a background image, place it in img folder.
d.      Type the following code in Notepad and save it in your Site Project folder.
<!doctype html>
<head lang="en">
<meta charset="utf-8">
<title>Primer on Theory of Relativity</title>
   <link rel="stylesheet" href="css/style.css">
<head>

<body>
<div id="container">
    <header>
        header
    </header>

    <nav>
       nav
    </nav> 
     
    <section id="main" role="main">
        <article>
            <h1> Primer on Theory of Relativity </h1>
        </article>       
    </section>
     
    <aside>
       sidebar
    </aside>
     
    <footer>
        footer
    </footer>
</div> <!--! end of #container -->
</body>
</html>

e.      Save as index.html, do not close Notepad.
f.        Open new instance of Notepad, type the following rules:
/* =============================================================================
   Primary styles
   Author:
   ========================================================================== */

header {
  background-color:#DC6F65;
}

nav {
  background-color:#70996A;
}

section#main {
  background-color:#EBEBEB;
}

aside {
  background-color:#8CCAF0;
}

footer {
  background-color:#993398;
}

g.       Save it with a filename style.css in your css folder.

Throughout the rest of this tutorial you'll often be modifying existing rulesets in your css file, ie. style.css.
Let’s give some of these elements a starter heights so we can start to visualize the layout. Modify these sections of the CSS: and it's time to add a new line to it, and displayed with these mark! /*+*/ add these lines to your style.css rule.
header {
  background-color:#DC6F65;
  height:150px; /*+*/          
}

nav {
  background-color:#70996A;
  height:40px; /*+*/
}

footer {
  background-color:#993398;
  height:100px; /*+*/
}

Save your css rule!

1.      Now, go back to your index.html file, then add the following below the: <h1> Primer on Theory of Relativity </h1>

<p>
The theory of relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century is one of the most significant advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion.
<br> This does not have a major impact on a person's day-to-day life since we travel at a speeds much slower than light speed. For object travelling near light speed, however the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on earth.
</p>

2.      Type the following list inside your nav tag. It looks like this:

<nav>
    <ul>
        <li><a href="/">Home</a></li>
        <li><a href="/about">About Us</a>
          <li><a href="/products">Products</a>
<ul>
            <li><a href="/labsupplies">Lab Supplies</a></li>
            <li><a href="/books">Books</a></li>
     </ul>
<li><a href="/services">Services</a>
<li><a href="/contact">Contact</a>
    </ul>
</nav>

3.      Type the following list inside your aside tag. It looks like this:

<aside>
   <h2>Topics</h2>
   <ul>
       <li>Climate Change</li>
       <li>Sea Level</li>
       <li>Exploration</li>
       <li>Results</li>
       <li>Resources</li>
    </ul>
</aside>
4.  Type the following list inside your footer tag. And so it looks like this:

<footer>
    <p id="about">We're a full-observatory and action bureau with service-people globally.
    Call us, let us improve our living with deepest concern to environment!</p>
    
    <div id="footerlist">       
        <h3>Contact</h3>
          <ul>
              <li><a href="/email">Via Email</a></li>
              <li><a href="/contact_form">Web Form</a></li>
              <li><a href="/pigeon">Carrier Pigeon</a></li>
          </ul>
      </div>
      
      <p id="footercopy">All content © 2014, Yourname </p>

</footer>
This completes your document structure in HTML5, now you’re just going to style this HTML5 document by modifying the style.css rule sets. Go on, explore and discover the beauty of creating web page with style. Just a reminder, every time you create modification in your style.css file, refresh the index.html file in your browser to see the result. To start:

1.      Add this code in your style.css file to create padding, it looks like this:
section#main, aside, footer {
  padding:10px;
}

2.      Now, since we don't want our design stretching full-width across the browser, let's give the content area a width, and center it on the page. Add this below your custom styles:
div#container {
  width:960px;
  margin:auto;
  margin-top:20px;
  border:1px solid grey; /*+*/
  border:1px solid #4B4B4B;
  border-radius: 20px;
  border-top-left-radius: 20px 20px;
  overflow:hidden;
  box-shadow:0 0 15px #333;
 }

aside, footer {
  padding:10px;
}
3.      Then line up the section main and aside by assigning width and float rule by adding the rule set to your style.css.
section#main {
  background-color:#EBEBEB;
  width:710px;
  float:left;
  padding-left:25px;
  padding-right:25px;
  padding-bottom:20px;
}

aside {
  background-color:#8CCAF0;
  width:180px;
  float:right;
}

4.      The footer has been swallowed up by section-main and aside floats; to display footer, add this code to your style.css. below the line: “height:100px;”

clear:both; /*+*/

(This is your webpage's initial view)

Below is your webpage' expected output after completion of this activity.
