Let’s start by cruising over to the USGS’s front page at… http://www.usgs.gov/
Just look at it. Ah! It’s just grand isn’t it?
- Below,
please give me the titles of the featured topics and the day you saw this
page.
- Click
on the “Geomagnetism” link in the "Hazards" section. What the heck is this page
for?
Now let’s go to… http://egsc.usgs.gov/isb/pubs/booklets/symbols/
I know that’s a lot of typing.
- Click
on the “Elevation” link and find out what the symbol for a depression is
and draw in here…
- Click
on “Land Surface Features” in the left column and below show me the symbol
for a quarry or open pit mine.
Now let’s cruse over to… http://www.terraserver.com
- What
is this website for?
- Now
on the left in the location section, type in
“North Royalton, Ohio” in the box to the left and hit enter. What are the
latitude and longitude of the city?
- Look
at the map and move around it a bit. What landmarks can you find?
- What
is the exact latitude and longitude of Gibson Field (the football stadium
behind the high school)?
- See if
you can find the latitude and longitude of your house. Write it below if
you can.
Search the web for these answers.

country was the first to produce a complete set of topographic maps of its

- Now
Google search “topographic maps” and hit “images” (Note: You can’t do this
at school, because image searches are blocked). Which of the images on the
first page is your favorite? Give its address and say why you like it.
