Topographic Maps Topography is the shape of the land A topographic map shows the shape of the Earth’s surface by using contour lines.

What is a Topographic Map? A map that shows the _____ of the Earth’s surface by using contour lines. Answer Bank Upstream Equal Side Shape Circles steep

Every Where on the contour line, The elevation is 400 meters Contour Lines Contour Lines are imaginary lines that join points of equal elevation above or below sea level.

Every Where on the contour line, The elevation is 400 meters What are Contour Lines? Imaginary lines that join points of _____elevation above or below sea level. Answer Bank Upstream Equal Side Shape Circles steep

Contour Interval The Contour Interval is the difference in elevation between one contour line and the next. Can you figure out the contour interval on the map to the right?

What are the elevations indicated by the letters on the map below? Contour interval –20 meters (m) Contour Interval = A = B = C = D = 740ft 700ft 820ft 770ft 20ft

What is the Contour Interval? The difference in ____ between one contour line and the next. 100 meters between 800 & contour lines 100/5= contour interval Contour interval = 20 meters Contour Interval = 20 meters Contour Lines Answer Bank Upstream elevation Side Shape Circles steep

PROFILE A profile shows a side view from a flat topographic map. BA

Step 1: Draw a transect line. Sometimes the line will be drawn for you Step 2: take a sheet of paper and make “tick” marks where each contour line intersects the map Step 3: record elevation at each tick mark How To Make a Profile Listen Carefully!!!!

Step 4: take your sheet of paper and plot your elevation points on a graph Step 5: Draw a line through your points How To Make a Profile Listen Carefully!!!!

Answer Bank Upstream Equal Side Shape Circles steep What is a PROFILE? A ____ view from a flat topographic map.

Contour Mapping Rules In order to make a contour map, there are rules we first must understand. These rules will help us determine the topography and shape of the land

Contour Mapping Rules 1. Hills and depressions are represented by circles. Hachure Lines are used to show depressions. HillDepression

Contour Mapping Rules 2. Contour lines never cross.

Contour Mapping Rules 3. When contour lines meet a river or a stream they form a “V” that points upstream.

“V’s” Point upstream

4. Contour Lines close together = steep slopes Contour Lines far apart = flat gentle slopes B A B A Contour Mapping Rules

Changing from top to side The closer the lines, the steeper the terrain The farther apart the lines, the flatter the terrain

What are contour map rules? Hills and depressions are represented by _____. Hachure Lines show depressions Contour lines never cross!!!! Contour lines that cross a river form a “V” that points_____ Contour Lines close together = ____ slopes Contour Lines far apart = flat areas Answer Bank Upstream Equal Side Shape Circles steep

Summarize: Answer Bank hill Write the sentences below. Use the map you drew for help: The map I drew has a Contour interval (CI) of ___ Location B has an elevation of ______ ft Location C has an elevation of ______ ft The circles on my map represent a ____ Please Draw B C

Topic: California Hazard Maps Objectives: Day 3 of 3 I will know the unique geologic provinces of California I will be able to analyze and interpret California hazard maps I will be able to identify which areas of California are prone to earthquakes, floods, tsunamis, and volcanic eruptions Unit: Maps
