Map: a flat representation of earth’s surface What is a map? Maps include 4 main features: Title: tells us what the map shows Scale: shows us what the distance is in real life Legend: identifies symbols on a map Compass rose: shows directions on a map What is a map? Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

topography – the shape of the land that includes the area’s elevation, relief, and landforms elevation – the height above sea level of a point on Earth’s surface relief – the difference in elevation between the highest and lowest parts of an area landform – a feature of topography, such as a hill or valley, formed by the processes that shape Earth’s surface.

Maps and globes are drawn to scale and use symbols to represent topography and other features on Earth’s surface. scale – relates distance on a map to a distance on Earth’s surface symbols – used by mapmakers and can be shapes or pictures to stand for features on Earth’s surface; can stand for a physical feature or a man-made feature

What are the cardinal directions? Cardinal directions: North, South, East, West What are the cardinal directions? N W E Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes S

What are the intermediate directions? Cardinal directions: Northeast, Southeast, Northwest, Southwest What are the intermediate directions? NW NE Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes SW SE

equator – an imaginary line between the North and South Poles dividing the Earth into Northern and Southern hemispheres prime meridian – imaginary line connecting North and South poles dividing Earth into Western and Eastern hemispheres

Lines of latitude and longitude are used to find location on Earth latitude – distance in degrees north or south of the equator longitude – distance in degrees east and west of prime meridian

What is a topographic map? Topographic map: a two-dimensional way of showing a three-dimensional image of Earth’s elevations Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Before eruption

After eruption

contour lines – represent elevation, relief and slope and connect points of equal elevation contour intervals – change in elevation from one contour line to another

Widely separated contour lines indicate a gentle slope Contour lines close together indicate a steep slope.

What are the features of topographic maps? Relief: the difference in elevation between 2 points Higher elevation – lower elevation = relief Teacher Actions: Direct students to record information on the RH side of their notebook Student Actions: Students record notes

Final Exam The diagram below represents a portion of a contour map. Which of the following best describes the physical feature represented by this contour map? a flood plain with creeks and streams a valley with two gently sloping sides a hill with slopes that vary in steepness a series of rivers flowing in concentric circles Teacher Actions: Use quick quiz strategy. Assessment (i.e. SAT or ACT practice, Writing: RACE+C) NY Regents 3. Energy is produced within the Sun’s core by the process of insolation nuclear fusion conduction radioactive decay
