Line graph population growth,1750 to 2150

The line graph shows population growth in richer or more developed and poorer or less developed countries between 1750to2150. It is based on United Nations World population prospects, the 1998 revised and estimated by the Population Reference Bureau.

 In 1750 the world population was below 1 billion but in 1800 there was a slight increased in both developed and undeveloped countries. The growth in 2000was increased up to 6.1 billion but the increase was more dramatic in less developed countries than more developed countries. The population in more developed countries stayed the same from 2000 to 2010. Also they expect it to be the same from 2011 to 2150.less developed countries saw a bigger increase from 2000 to 2010. The population growth is estimated to reach 11 billion in 2150. From 1950 to 2000 world population increased three times. The more developed countries had slight growth but were still below 1 billion.

All in all, I think less developed countries expect to be more than 10 billion population.

Line Graph three African cities

The line graph gives information about the average monthly temperatures in three African cities - Mombasa, Cairo, and Cape Town. Each city has its own different climate, with very different characteristics.

The hottest place shown on the graph is Cairo. In July and August, average temperatures rise to over 80º Fahrenheit. However, Cairo also has the biggest variation in climate. Temperatures drop to as low as 55 degrees in Cairo’s winter, during January and February. This is equal to Cape Town’s lowest temperature in July. In fact Cairo and Cape Town are almost opposites in temperature. Cairo is hottest when Cape Town is coldest.

Cape Town does not have the range that Cairo has. Its maximum temperature is 70º F from November to February, after which it drops gradually to about 55 degrees in its winter. In contrast to Cairo or Cape Town .

Mombasa is warm all year round. Its temperature fluctuates very little, ranging from a low of 75 to a maximum of 83 in March.

In conclusion, location is very important in deciding climate. When it is winter in Cairo, it is summer in Cape Town, but Mombasa, being tropical, is warm all year round.

Reflection 3

We use 4 paragraph formats for the problem solution essays.

1 introduction: write your plan about the body and explain the solutions and problems

2 problems: write 4 causes of the problem about the subject that given to you

3 solutions: write the solutions that you wrote the problem about 

4 conclusion :  summarize the solutions and say which is most viable.

Then we moved to the graph; first we did the pie chart and compared between them and their percentage. After that, we practiced the bar chart, mostly between the countries. And last but not least we focused on the table chart and it was easy to understand.

Hurricanes and Tornadoes

This table shows the differences between two very strong winds: hurricanes and tornadoes.

A hurricane can be predicted 2-3 days in advance for a wide area and 6-10 hours beforehand, but a tornado can be predicted 20 minutes or less. The minimum wind speed for tornadoes is 40 miles per hour, whereas for hurricanes it is 74 miles per hour. A hurricane has 300 miles of average width of storm and a tornado is 100-600 meters sometimes up to 1.5 km wide. Hurricanes start over warm oceans whereas tornadoes start usually over land. The hurricane is classified on the Saffir-Simpson C1-c5, but the tornado is classified on the Fujita F0-F5. Finally, the average number per year for hurricanes is 100 worldwide.

As you have seen, the tornadoes cause much damage in a few minutes with maximum wind speed 300 miles per hour, but a hurricane's duration will be one week on average.
