Lesson 1 - Some Early American Cultures
5,000 to 10,000 feet
About 1400 miles or 2,250 kilometers
0 to 500 feet
2,800 miles or 4,500 kilometers
Mexico City is at a higher elevation. Temperature drops as elevation increases.
5,000 to 10,000 feet
Probably the Aztec culture
Similar terrain and climatic conditions
Lesson 2 - Paving the Way for Columbus
The long distance the goods had to travel to reach Western Europe
About 8,500 miles or 13,650 kilometers
Possible routes would be north through the Arctic Ocean then south through the Bering Strait; or south around Africa then east across the Indian Ocean; or south around the southern tip of South America and then west across the Pacific
South around the southern tip of Africa and then east across the Indian Ocean to the Molaccas. Europeans of the time already knew about problems with ice in northern Europe
No one in Europe knew where the southern end of Africa was, or even if it had an end, and if so, if such a voyage was possible.
Lesson 3 - Voyage to the New World
25,000
360
69 miles
Yes - but only at the equator, because lines of longitude get closer together as they near the poles
20,160 miles
Spain
Canary Islands
The West Indies
Cuba and Hispaniola
Caribbean Sea
To take advantage of the prevailing current and winds - the winds drive the currents
North Equatorial Current
A warm current
About 3,500 miles or 5,600 kilometers
Yes
106 miles per day
Columbus wanted to take advantage of the easterly moving currents and winds so his route was northeast from Hispaniola to the easterly flowing current and winds at about 30N, then more easterly to the southern most island in the Azores then to Lisbon, Portugal and from there back to his starting point.
Lesson 4 - The Colonial Period
About 1,500 miles or 2,400 kilometers
The Appalachian Mountains
Green
That the elevation is between 0 and 500 feet above sea level
Variations of any of the following should be considered correct: 1. the low lying lands was well watered and fairly level, thus more suitable for agriculture; 2. the lack of good roads in the new colonies required that people live near the navigable parts of rivers for travel and the transportation of goods; 3. colonists had not been in the New World long enough to push the frontier very far west; 4. most of the manufactured goods needed in the colonies were still imported from Europe, and the settlers wanted to be near the seaports where goods were more easily available
Lesson 5 - Growth of the New Nation
Because the United States ended at the Mississippi River at that time, and this area would have been in the northwest corner of the United States
Ohio, Michigan, Illinois, Wisconsin, Indiana, and a part of Minnesota
Chicago and Detroit
500 to 1000 feet and 1000 to 2000 feet
Farming
Lesson 6 - The Louisiana Purchase
Arkansas, Oklahoma, Missouri, Iowa, Kansas, and Nebraska, South Dakota, North Dakota, Louisiana, Texas, New Mexico, Colorado, Wyoming, Montana, and Minnesota
Between 0 and 500 feet
5,000 to 10,000 feet
Because the boats would be traveling upstream against the current
About 800 miles
Slightly over 6 miles per day
The Great Plains
In western Montana
Dangerous rapids, water falls, and very swift moving water
Lesson 7 - The Transcontinental Railroad
About 1500 miles or 2400 kilometers
More
Because the physical features of the land would not have allowed the tracks to follow a straight line
About 444 miles
Slightly less than two and one half hours
On the west side of the Sierra Mountains where the elevation changed abruptly from 0 to 500 feet to over 5000 feet in elevation
Heavy snows
Lesson 8 - Dust Bowl Travelers
From 0 to 500 feet
A valley
Oklahoma, Texas, New Mexico, and Arizona.
About 1100 miles or 1,770 kilometers
Lesson 9 - The Cold War
Because the shortest distance between most of the Soviets' missile sites and the United States is by way of a north polar route.
5,700 miles or 9,170 kilometers
About 23 minutes
Lesson 10 - Apollo 11
The moon
Lesson 11 - The Vietnam War
Hanoi
Laos and Cambodia
The South China Sea
7,800 miles or 12,550 kilometers
