The 5 Themes of Geography
Theme What it tells us about Geography
Location Where are we?
Place What’s it like there?
Interaction How do HUMANS and the ENVIRONMENT affect each other?
Movement How do HUMANS and other HUMANS interact together?
Region What links where we are to the places around us?
Location – Where are we?
Place – What’s it like there?

Region – What links where we are to the places around

We are part of the same “regionregion” even though ” even though we are called by two different names. We have similar we are called by two different names. We have similar climatesclimates (weather) and similar types of (weather) and similar types of landland. We even . We even share some important landforms like the Appalachian share some important landforms like the Appalachian Mountains.Mountains.
Maps and Globes
A globe is a scale model of Earth. It shows the
actual shapes, sizes, and locations of all
Earth’s landmasses and bodies of water.
Understanding Globes
Lines of Latitude – Imaginary horizontal lines around the globe.
*Also called Parallels
Lines of Longitude – Imaginary vertical lines around the globe.
*Also called Meridians
Together, these lines form the global grid. Every place on the earth has its own set of coordinates on the global grid.
• To help us find our location on the earth easier, we break our earth down into parts, or hemispheres. We divide our planet into North and South halves, OR into East and West halves.
• Which 2 hemisphere’s do we live in?
Earth’s Hemisphere’s
Map Projections
Types of Maps:Types of Maps:
• Same-Shape Maps Same-Shape Maps (Mercator Projection): (Mercator Projection): Accurately show the Accurately show the shapes shapes of landmasses, of landmasses, but distort the but distort the size size of of landmasses and landmasses and distances distances between them.between them.
• Equal Area Maps: Equal Area Maps: Show Show the correct the correct size size of of landmasses, but distort landmasses, but distort their their shapesshapes, especially , especially at the at the edges edges of the map.of the map.
• Robinson Maps: Robinson Maps: Gives a Gives a full overall picture of the full overall picture of the world. Keeps the world. Keeps the size size and and shape shape correct for correct for most continents and most continents and oceans, but distorts the oceans, but distorts the size of the size of the polar polar regions.regions.
Maps are drawings that show regions on flat surfaces.
Maps are easier to use and carry than globes, but they cannot show the correct size and shape of every feature on Earth’s curved surface. They must shrink some places and stretch others.
To make up for this distortion, map makers use different map projections. No one projection can accurately show the correct area, shape, distance, and direction for all of Earth’s surface.

By looking at the country of Greenland on each map, we can see how different objects appear in different ways on each map.
How to use a map

• Scale Bar: Scale Bar: Helps you Helps you find the actual find the actual distances distances between between points shown on the points shown on the mapmap..
Mapmakers provide several clues to help you understand the information on a map.
Maps provide different clues, depending on their purpose or scale.
Most maps have several clues in common.
Political and Physical Maps
