Links to the World- Internet Sites
You've been revving your engines, and itching to hit the
SuperHighway, right? Here, we will extend our use of
anchor tags to create links to resources out there on the
After this lesson you will be able to:
- Create an anchor to link to an Internet site.
- Quickly copy the URL for a site and use it in your HTML document.
Note: If you do not have the working document from the previous
lesson, download a copy now.
HTML for Anchors to the Internet
Linking to a site on the Internet combines what we have worked on
earlier in the lessons on Links to Local Files (Lesson 8a) by incorporating what we have
learned about URLs (Lesson 8b). The
full HTML format for an anchor link to an item on the
<a href="URL">Text to Activate Link</a>
where URL is the full Uniform Resource Locator, in quotes,
the address for the Internet site where you want to send the viewer.
The string Text to Activate Link is what will show up as hypertext
in your WWW browser (usually but not always) underlined and in blue.
When a viewer clicks on this hypertext, the WWW browser will link
them to the Internet site indicated by the URL. Remember that a URL
can be a link to another World Wide Web (WWW) server, Gopher
server, FTP site, or any text, graphic, sound, video file on these
Now, we will add a hypertext link to a NASA site that has information about
volcanoes on the planet Mars. Follow these directions to add anchor
links on your HTML document:
- Open your Volc.html file in the text editor.
- Below the heading, Volcanic Places on Mars, enter
the following text:
Mars</a> has its fair share of volcanic landforms,
including the largest volcano in the universe,
Note: We've made a link to two different types
of information. The first hyperlink connects to a WWW page
that describes information about the planet Mars. The second is a link to
a small GIF image of a Martian volcano.
- Save and Reload in your WWW browser
A Quick 'n Easy Way to Enter URLs in Anchor Tags
As you navigate among documents in the WWW, the URL of the currently
visible page can be displayed at the top of the WWW browser window
(You may have to look for a menu option to Display URLs). For
example, in this document, the URL looks something like:
You can use your mouse to select and copy a URL from the
WWW browser display and then paste it in the anchor tag of your
HTML document. This is much more efficient than writing URLs down
on paper (some are quire long!). You can also use the bookmark or hotlist features of your
web browser. Or, you can keep a text document available where you can
cut and paste new URLs.
Now we will add some links to other sites that we will list under the
References section of our Volcano lesson. One such site that might
offer relevant information is the US Geological Survey.
Follow these steps:
- Connect to the
US Geological Survey Education Index.
- From the WWW page, use the mouse to Select the URL as displayed
in the URL display field.
- From the Edit menu, Copy the URL.
- Open your HTML document in the text editor
- Under the heading "References", enter:
<li> <a href="">Educational Resources from the
- Click the mouse once between the two quote marks and Paste
the text you copied in step (3) The final anchor tag should
Educational Resources from the USGS</a>
Note: You have just set up the HTML structure for an
Unordered List, with each list item a hypertext link to a site that offers
information about volcanoes. For a review of Lists, see lesson 6
NOTE: Users of NetScape can get URLs in another way. For Macintosh versions, just hold the mouse down on any
hypertext on a web page and when the popup menu appears, select
Copy This Link Location. In the Windows version, hold down the right
mouse button to get this same menu. Now you can just paste the URL in your
For additional practice, explore some of the following Internet
sites with resources Geology and/or Volcanoes. Add at least two
more items to your Reference section:
- Sites with Information on Volcanoes:
Alaska Volcano Observatory
Cascades Volcano Observatory
Michigan Tech Volcanoes Page
NASA Earth Observing System (EOS) IDS Volcanology Team
NASA Facts: Volcanoes and Global Climate Change
NGDC Natural Hazards Data
Smithsonian Global Volcanism Program
Volcano Watch Newsletter
JASON Project VI: Island Earth
- Sites with Information on Natural Hazards:
Disaster Information *
Preparedness Information eXchnage (EPIX) *
NGDC Natural Hazards Data
- Sites with General Information in Geology:
Observation Systems (EROS) Data Center *
Internet Catalog *
Internet Connections *
Information Server *
Planet Earth Home
United States Geological Survey *
Internet Catalog *
Check Your Work
Compare your WWW document with a sample
of how this document should appear. If your
web page was different than the sample or the links do not
properly connect to a remote site, review the text you entered in the
text editor. Note that your list of references may be different from
- What is the address for an item on the Internet?
- What steps did you take for creating an anchor link to the NASA
- What shortcut was identified for putting an URL into an anchor
- Tell a neighbor about any other Internet anchor links that you
put in your document.
Create anchor links from your own WWW document that connect to
some of the URLs addresses you have discovered.
In the next lesson you will create links that connect to different
sections of an HTML document.
