Week of November 6, 2016
I have been researching why this map has so many lines running up and down and across, and Meri finally explained it to me. Here is the lowdown on these lines. The lines that run up and down the map (north and south) are called longitude lines. These lines are used to measure degrees east or west from the prime meridian. The prime meridian is located at 0 degrees longitude. This imaginary line runs up and down through France, Spain, Antaractica, western Africa, and the United Kingdom. The prime meridian divides the world into the eastern hemisphere and western hemisphere. (Hemisphere means half of a sphere). The lines that run across (east and west) a map are called latitude lines. Lines of latitude measure degrees via north or south. The equator is at 0 degrees latitude. This imaginary line marks halfway between the North Pole and the South Pole. The equator runs though parts of Asia, South America, and Africa. This imaginary line also divides the world into the southern hemisphere and northern hemisphere. Longitude and latitude are both used to measure distance in "degrees". I am still trying to think of way to tell the two kinds apart. Wow, Meri just taught me an easy way to remember the directions of the lines. Think of latitude as a "ladder" (kind of sounds similar). The steps of a ladder go up and down just like the lines of latitude go around the map. I put some pictures in my blog to better explain this confusing geography stuff. Both lines (latitude and longitude) start at 0. These lines are drawn only on maps and globes. So, don't expect to see an "equator line" on the streets and beaches of Brazil! I wonder how longitude and latitude help us -- or why they are even used? Meri explained that the purpose of longitude and latitude is to help identify your specific location on the earth's surface. Uncle GT also emailed me this neat picture of a globe/map (it really helped me to understand what all of those lines represent). See my pictures, below.

Uncle GT called today and told us to "hang tight" in Brazil. He hadn't heard any updates about Dewey, the truth-sniffing dog. We are to keep our cell phone with us at all times and take some time to explore this huge country. Geo and I are taking a helicopter to the Amazon Rainforest in about an hour. I can't wait to go explore the rainforest. Our trip includes a canopy tour. Do you know what that is? A canopy tour takes you through the rainforest via steel cables and platforms. We are going to be kind of like Tarzan gliding through the rainforest. The steel cables and platforms are installed on trees between 10-20 meters from the ground (that would equal 30-60 feet). Holy Idaho! I can't wait to get gliding. Geo is excited too. We will be gone all day - so we will write more tomorrow. We just received a text message from our little sister, Pandora.
Text from Pandora: WAYN? RUOK?
Text to Pandora: ABT2 go on canopy tour in Amazon. In btfl C-T in Brazil
The Amazon canopy tour was the most thrilling experience of my entire life. Meri was a bit nervous to get started, but once she got going - she loved it too! I pasted some pictures of the Amazon rainforest below. I also pasted a picture of another tourist on a canopy tour (this is the person who went after Meri).
Tonight we received an odd text message from an unknown caller:
Text Message from unknown number: J2LYK - We R NW of Brasilia. We R in a country located in the N and S hemispheres. Capital c-t begins with a B. Dewey is here - where could we be?
In the words of Meri, "Holy Idaho". Take a look at the map and see if you can figure out where we should go next? The country is in the northern hemisphere and southern hemisphere, so that must mean that the equator runs through the country. The capital city begins with a B? And they are northwest of Brasilia. Should we travel to the capital of Chile, Colombia, or Ecuador? Take a look at the map and help us out!
