Bell Ringer: Respond in your blog • Go to this link and read the article: • http: //www. telegraph. co. uk/earthnews /3884623/Scientists-discover-new-forest-withundiscovered-species-on-Google-Earth. html • Do you think there is anything left on Earth we have not yet discovered? • Why is location important?

Where Am I? • The answer is your location. • Absolute location: exact location

Where Am I? • The answer is your location. • Absolute location: exact location using coordinates of latitude and longitude • Relative location: your location relative to objects around you or other locations. • Think! What is your location relative location right now?

Themes • Place: describes characteristics of a location. • Physical Characteristics: geographic features (i.

Themes • Place: describes characteristics of a location. • Physical Characteristics: geographic features (i. e. peninsula, river delta, plains, mountains) and terrain). • Think! What are some other geographic features you know? List them in your blog. • Human Characteristics: things people bring to a place; including cultural diversity, architecture, pollution, agriculture.

Where Am I? • Region: We break down the globe into smaller geographic areas

Where Am I? • Region: We break down the globe into smaller geographic areas with to make studying them easier. • A region can range in size. • Locations within a region share common characteristics (i. e. physical features, climate, cultural diversity, economic class).

Themes • Movement: the shifting of goods, people, and ideas from one place to

Themes • Movement: the shifting of goods, people, and ideas from one place to another. • Think! How has the Internet affected the movement of goods, people, and ideas? • Man vs. Environment: As long as humans have been around, we have been interacting with the world around us. • Think! How have humans interacted with the environment in your city? Record one positive effect and one negative in your blog.

Types of Maps: • Physical: show geographical features such as mountains, rivers, oceans, etc.

Types of Maps • Political: show artificial boundaries of states & countries; also mark important places like major cities.

Types of Maps: • Historical: illustrate something that has changed over time (i. e.

Types of Maps: • Historical: illustrate something that has changed over time (i. e. human population or political boundaries).

Types of Maps continued… • Maps are a cartographer’s representation of a place; thus, they are drawn in different ways called projections. • The most commonly used is the Robinson projection:

Types of Maps continued… • Another commonly used projection is the Mercator projection: •

Types of Maps continued… • Another commonly used projection is the Mercator projection: • Think! What are some differences in how distances and continents appear?

Latitude and Longitude • Latitude and longitude are imaginary lines that form a grid

Latitude and Longitude • Latitude and longitude are imaginary lines that form a grid pattern on a globe or map projection. • We use this grid to specify our absolute location using coordinates of latitude and longitude.

Latitude • Latitude lines run horizontally around the globe, like a belt. • We

Latitude • Latitude lines run horizontally around the globe, like a belt. • We call these lines parallels • Ex: 30˚N

Latitude • The North and South Poles are located at 90˚N and 90˚S, respectively.

Latitude • The North and South Poles are located at 90˚N and 90˚S, respectively. • The Equator is located at 0˚ latitude. • The Tropics are warm year round.

Spatial Relationships • www. youtube. com/watch? v=Dui. Qv. PLWzi. Q • Think! Given the spatial relationship of Earth with the Sun, why is this true?

Longitude • Longitude lines are imaginary lines that are drawn vertically from N to

Longitude • Longitude lines are imaginary lines that are drawn vertically from N to S poles. • Called meridians. • The Prime Meridian runs through Greenwich, England is located at 0˚ longitude. • All other meridians are measured E or W of the Prime Meridian, Ex: 30˚E

Hemispheres • Term that describes half the globe • Can be divided into N

Hemispheres • Term that describes half the globe • Can be divided into N or S hemispheres or E and W hemispheres.

Location & Technology • GPS (global positioning system)- a digital satellitebased device that shows your absolute location almost anywhere on Earth. • Google Earth- a 3 -D satellite mapping system of almost every locale on Earth. • Think! What are some uses for these innovative devices?

Core Connection: • Science: What do you know about the Earth and its relationship

Core Connection: • Science: What do you know about the Earth and its relationship with other celestial objects in space? How do these relationships affect life on our planet in terms of days, months, years, and seasons? • Math: If the Earth is a sphere, how many degrees East or West can we travel before finding the same ring of longitude? How many degrees North or South can we go before reaching a Pole?
