Contour Maps! MCAS Bootcamp: Day 1

Random Fact of the Day 238,857 miles On average, what is the distance in miles between the Earth and the Moon? 238,857 miles

Contour Maps Use (contour) lines to tell elevation. Elevation: How high or low the ground is from the ocean.

Contour Lines They represent a change in height or elevation This Map: Every 20 Meters Everything touching the same line is at the same elevation

Contour Lines and Elevation Imagine if you drew lines around a mountain every 20 meters. Top pictures=Contour Map (From an Airplane) Bottom Pictures =Side View (Walking in real life)

Contour Lines and Elevation The closer the contour lines are to each other, the steeper the slope of the hill is!

Circles Form Around Hilltops/Ridges Gaps form Around Valleys/Ravines

Stream or River Contour Lines Contour lines that cross a stream or river make a V shape that points up stream to the water source that created the river.

Hachure Marks (Short inward pointing lines) Hachure Marks on a contour map show a depression or crater (sunken spot in the landscape).
