Over the past week, Boston Public Schools has decided to forego the use of the Mercator projection in classrooms. What is going to replace the projection? The Gall-Peters. Why? Africa and South America appear small on the map.
This is the thing about the Gall-Peters projection. It is no less distorted than the Mercator projection. Both are distorted. The Mercator was distorted when it was presented by the person it was named for, Gerhardus Mercator. It wasn’t even meant for classrooms when it was made. It was for sailors. On the Mercator, Greenland appears as big as South America.
The Gall-Peters is no good for public schools either. Distortion takes place there as well. The areas around the poles look small because of the east/west stretching. The areas around the Equator look elongated.

In honor of World Meteorological Day, the 2017 theme is about clouds. This entry will discuss fog vs mist. Why?
Fog can be described as a cloud that touches the ground. It is not like what you would see in the sky. Fog is comprised of cloud water droplets. Those droplets are suspended very close to the earth’s surface.
What differentiates fog from a regular cloud is the fact that fog is very low lying. Regular clouds are further away from the earth’s surface.
Mist is also low lying, very close to the earth’s surface.
What is the difference between fog and mist?
VISIBILITY. Remember this. If visibility is less than 1 km, that is fog. In the UK, fog is defined by a visibility less than 100 metres.

23 March is World Meteorological Day. This is a day to reflect on weather and the physical processes involved. This entry’s theme is this: Meteorologists are geographers.
How are meteorologists geographers? Weather, climate, and geography are connected. Geography determines weather and climate. This is why we have phenomena like El Nino, orographic lift, chinook/foehn winds, and lake effect snow.
Meteorologists have to study geography in order to get a idea how weather and climate works in different places. Weather and climate takes place over a spatial scale. Meteorologists study the earth and its processes. Meteorology is a geoscience. Geography is involved. Meteorology is classified as a subfield of physical geography.
So much of how weather works is related to geography, as well as science. Physical features of the earth, how those features affect atmospheric conditions, atmospheric conditions themselves. This is part of what meteorologists study. The impact on humans is another part studied.
20 March marks International Day of the Francophonie. It is to promote and celebrate the Francophone world, of the French language. Over 270 million people speak French. 80 million speak French as a first language. This language is spoken in 29 nations throughout the world. It is not only France where it is spoken. One can find French speaking people in other parts of Europe, Africa, South America, North America, Asian, Oceania. From Montreal to Cayenne, from Beirut to Kinshasa, from Paris to Noumea, from Geneva to Port au Prince, one can here French spoken, whether it’s the primary language or the secondary language.
Joyeux Journée Internationale de la Francophonie!!
Biogeography is about the spatial distribution of species and ecosystems. In this case, the great blue heron and where you can find it.
Remember this. This is a large, wading bird. Wading as in wading in the water. Want to find this bird? Look for wetlands and rivers. This bird can be found through most of North America.

What is a tidal island? Well, it’s an island found in the tides. Simple, right? Well, there is a little more to it than that.
A tidal island is a landform connected to a larger piece of land by some kind of bridge, man-made or natural. When high tide takes place, that natural or man-made bridge disappears under the water. An island is formed as a result. An island is basically a piece of land surrounded by water on all sides. The tides basically form this island.
Tidal islands have been used by used by humans for religious retreats and fortifications. Mont Saint Michel in France is an example of both. To learn more, watch the video below.
