Each year, new seafloor is added at the Mid-Atlantic Ridge. The Atlantic Ocean widens, causing North and South America to move farther away from Europe and Africa. Close to the ridge, rocks are younger. As you move away from the ridge, the rocks become older.
The rate of seafloor spreading has not been the same over time. In this activity, you will calculate the average rate of seafloor spreading and then determine when the seafloor started to spread.
1. Where would you find the oldest sections of seafloor, near the continents or near the Mid-Atlantic Ridge?
Working with Map Scales
Below is a map of a section of the North Atlantic. You can see the coastlines of North America and Africa. On both sides of the Mid-Atlantic Ridge, strips of seafloor are labeled with their ages in millions of years. Note the map scale.
2. What is the scale of the map? For this activity, you will use centimeters.
cm = km
3. Choose one strip of seafloor rock. What is the age of the rock?
4. Use your ruler to measure the distance of the strip from the Mid-Atlantic Ridge.
cm
5. Using the calculator, multiply the answer to #4 by 405 to figure out its distance in kilometers. Round to the nearest whole number.
km
Determining Rate of Spreading
Use the age of the rock you have chosen and its distance from the Mid-Atlantic Ridge to calculate seafloor spreading.
6. First you will find out how fast the seafloor is moving away from the ridge on one side. Use a calculator to divide the answer to #5 by the answer to #3. Round to the nearest whole number.
#5 km ÷ #3 million years = km/million years
7. Now find out how fast the seafloor widens every 1 million years. Multiply the answer you got in #6 by 2.
The seafloor spreads at a rate of km every 1 million years.
When Did the Seafloor Start Spreading?
The distance between Point A and Point B, or the coasts of Africa and North America, is 4,550 km. Using your answer to #7, find out when the Atlantic Ocean began to open. Divide 4,550 km by your answer in #7 to find out.
8. 4,550 km ÷ #7 = million years ago.
9. Look at the Geologic Timeline. During what geologic period did the Atlantic start to open?
See if you can figure out the rate of floor spreading (in cm/year) between North America and Africa.
10. #7 x 1000 m x 100 cm ÷ 1,000,000 years = cm/year
11. How far, in centimeters, has the distance between North America and Africa increased since you were born? Multiply the rate by your age.
cm
12. How much has the distance increased during the average lifetime of 82 years?
cm
13. How much closer were the continents when Columbus crossed the Atlantic in 1492?

There are four type of economic activities:
Primary activities: its involves the extracting, mining, farming, fishing etc activities. Secondary activities: Its involves manufacturing and production of goods such as making cars, steel etc Tertiary activities: Its involves providing a service such as teaching, medicine, nursing etcQuaternary activities: Its involves research and development industries which aims at improving the other three activities.Therefore, countries with these effective economic activities will have a developing economic system which will be influential in world.

Explanation:
Minerals used as ferroalloys such as chromium are essential to the production of specialty steels. Jet engines used in military aircraft are made of specialty steel. Political considerations can influence the import of resources from other countries. During the Cold War, communist countries such as the Soviet Union and China were not used as major suppliers of chromium because of military implications. Reset the map. Select Chromium Production by Country. Which of the following countries would be the best source of chromium for specialty steel production within the United States?
You did not open hints for this part.
a. South Africa
b. Brazil
c. Zimbabwe
d. India
e. Russia
Answer:
South Africa
Explanation:
During the Cold War South Africa was a major source of chromium for the United States. South Africa was considered the alternative to imports from the Soviet Union and the People’s Republic of China. Even though there was a world-wide embargo on South African commodities because of its policy of apartheid, the United States imported chromium from the world’s second largest producer. Even though Brazil is located closer to the United States, its chromium production is considerably less than that of South Africa.
The country that would be the best source of chromium for specialty steel production within the United States is South Africa.
This is because South Africa is known to have the highest deposits of chromium, with about 17,000,000 out of the 40,000,000 worldwide.
Also, South Africa was known to have supported the likes of the United States during the Cold War.
Options B and C are wrong because Brazil and Zimbabwe have no chromium deposits.
Option D is wrong because India stylishly supported the Soviet Union during the cold war; hence, they wouldn't have supplied the United States with the Chromium needed.
Also, option E is wrong because Russia forms the larger part of the Soviet Union, and till today they are still not on the same side in most political issues.
Hence, in this case, it is concluded that the correct answer is option A." South Africa."

1. Were you able to extract the chocolate chip without breaking the cookie? Why or why not?
2. How would you describe the process of mining based on this activity?
please answer correctly
Answer:
Explanation:
Many of the products we use everyday – from plastic water bottles to wrist watches and crayons to headphone wires – are produced from rocks and minerals mined from the earth. These rocks and minerals are considered a non-renewable resource because there is only a set amount of each and once it is used up, it will be gone forever. Some of these resources are very common and others are scarce. As the human population has grown, the demand for these resources has grown as well.
Extracting rocks and minerals from the earth is typically done by mining. Large scale mining operations are used all over the world and can often damage the
land on which they take place. Unfortunately, the
end result of mining (the profits made by selling the ore) can at times overshadow the damage done by the process (destroyed animal habitat, clear cutting of trees, pollution of local
streams, etc.).

What are the greenhouse effects on polar temperature records? Give examples
Answer:
Carbon dioxide raises global temperature by trapping heat that would otherwise escape directly into space. Also, warming temperatures in the Arctic may release even more carbon dioxide and other greenhouse gases such as methane, by melting frozen soil called permafrost. For example, melting glaciers and icebergs in the poles claim increasing heat.
