### Measuring Earth:

Measuring Earth Notes: Pages 3 - 9 ©Mark Place, 2009-2010 www.LearnEarthScience.com

### Earth’s Spheres:

Earth’s Spheres Information regarding Earth’s atmosphere can be found on page of the ESRTs

### Earth’s Spheres:

Earth’s Spheres Information regarding Earth’s interior can be found on page of the ESRTs

### Earth’s Spheres:

Earth’s Spheres Information regarding Earth’s hydrosphere can be found on page of the ESRTs

### PowerPoint Presentation:

Answers: 1. 4600°C, 1.2 million atmospheres (+/- 0.2) 2. oxygen 3. -90°C 4. 0°C 5. 12 km

### PowerPoint Presentation:

What is the purpose?

### PowerPoint Presentation:

Who uses topographic maps? the military miners police farmers

### PowerPoint Presentation:

When might someone use a topographic map? plan a hiking trip landscaping building homes road building

### PowerPoint Presentation:

Contour Interval? 25

### PowerPoint Presentation:

Contour Interval? Elevation of "A"? Elevation of "B"? 20 540 580

### PowerPoint Presentation:

Highest possible elevation? 619

### PowerPoint Presentation:

What do hachured lines show? areas of depression

### PowerPoint Presentation:

What are the rules concerning hachured lines? first hachured line has same elevation as previous contour line

### PowerPoint Presentation:

If north is at the top of the page, what direction is this river flowing? south

### PowerPoint Presentation:

Can a river flow north? yes!

### PowerPoint Presentation:

Name two ways that you can determine which way a river flows on a topographic map. contour lines point upstream rivers flow downhill

### PowerPoint Presentation:

What are the steps to draw a topographic profile place a piece of paper between the points mark where every contour line touches the edge of the paper determine the elevation of each mark place the paper on the graph and mark the elevation of each contour line

### PowerPoint Presentation:

Using the map and chart below, construct a topographic map profile.

### PowerPoint Presentation:

Please match the contour map on the left with the profile on the right.

### PowerPoint Presentation:

Topographic Maps---Distance Between Points What is the distance, in kilometers, from Kingston to Oswego? What is the distance, in miles, from Plattsburgh to Jamestown? 266 km 342 miles

### PowerPoint Presentation:

The elevation of Albany is 282 feet. The elevation at Binghamton is 1634 feet. Calculate the gradient to the nearest tenth of a ft/mi. Show all work. gradient = change in elevation distance = 1634-282 115 miles = 1352 ft 115 miles = 11.8 ft/mile

### PowerPoint Presentation:

The elevation of Watertown is 99m. The elevation at Oswego is 144m. Calculate the gradient to the nearest tenth of a m/km. Show all work. gradient = change in elevation distance = 144 - 99 75 km = 45 m 75 km = 0.6 m/km

### PowerPoint Presentation:

If the distance between the two circled cities is 425 km, calculate the temperature gradient to the nearest hundredth? Show all work. gradient = change in temperature distance = 82-48 425 = 34 425 = 0.08 °F/km
