The biggest tree

General Sherman

Read and talk with Tatiana

In terms of sheer volume, the giant sequoia (Sequoiadendron giganteum) known as General Sherman is a monster of a tree -- at 52,508 cubic feet, it's the world's largest tree, and perhaps the world's largest living thing. General Sherman is located in California's Sequoia National Park and is one of the park's premier attractions. The closest rival is a coast redwood (Sequoia sempervirens), nicknamed Lost Monarch, located somewhere in Jedediah Smith Redwoods State Park in northern California. Lost Monarch measures about 42,500 cubic feet.  Use the link

Atmospheric Circulation

Atmospheric Circulation One way to  transfer of heat from the equator to the poles would be to have a single circulation cell that was upward in the tropics, poleward aloft, downward at the poles, and equatorward at the surface. This is the single-cell circulation model first proposed by Hadley in the 1700’s.

Since the earth rotates, the axis is tilted, and there is more land mass in the northern hemisphere than in the southern hemisphere, the actual global pattern is much more complicated. Instead of a single-cell circulation the global circulation model consists of three cells for both N and S hemispheres. These three cells are the tropical cell (also called a Hadley cell), the midlatitude cell and the polar cell.
Surface Features of the Global Atmospheric Circulation System

Main wind belts:
Because the Coriolis force act to the right of the flow (in the Northern Hemisphere), the flow around the 3-cells is deflected. This gives rise to the three main wind belts in each hemisphere at the surface:
· The easterly trade winds in the tropics
· The prevailing westerlies
· The polar easterlies

Doldrums, ITCZ: The doldrums are the region near the equator where the trade winds from each hemisphere meet. This is also where you find the intertropical convergence zone (ITCZ). It is characterized by hot, humid weather with light winds, major tropical rain forests found in this zone. Migrates north in January and south in July.

Horse latitudes:The horse latitudes are the region between the trade winds and the prevailing westerlies. In this region the winds are often light or calm, and were so-named because ships would often half to throw their horses overboard due to lack of feed and water.

Polar font:The polar front lies between the polar easterlies and the prevailing westerlies.

Pressure belts:
The three-cell circulation model would have associated with it the following pressure belts:
· Equatorial low – A belt of low pressure associated with the rising air in the ITCZ. (The rising of warm air heated at the Equator causes an area of low pressure called Equatorial Low. As the air rises, creates clouds and precipitation.)
· Subtropical high – A belt of high pressure associated with the sinking air of the horse latitudes. (At the subtropics the air cools and descends creating areas of high pressure with clear skies and little precipitation, called the Subtropical High. The descending air is warm and dry, and produces deserts in these regions.)
· Subpolar low – A belt of low pressure associated with the polar front.
· Polar high – A high pressure associated with the cold, dense air of the polar regions.To learn more.

What is Drought? What do you think when you hear the word drought? Do you think “dry,” “hot,” “dusty,” or “cracked earth,” or even “no water”? If so, you’re on the right track! When a place is in a drought, it is dry and hot, often dusty; cracks may appear in the soil, and rivers, lakes, streams, and other sources of water can go dry. A drought means that a place has less precipitation (rain or snow) than normal over a few months or even longer. What causes this? How does drought really affect us? How can we be prepared for drought? These are all important questions that we will answer as we explore drought. What causes a drought?  How Does Drought Affect Our Lives?

Yoruba

The Yoruba people live in Southwest Nigeria and Benin. They have developed a variety of different artistic forms including pottery, weaving, beadwork, metalwork, and mask making. Most artwork is made to honor the gods and ancestors and since there are more then 401 known gods to the Yoruba there is much sculpture and artwork made. Because of the vastness in the number of gods, the Yoruba have been compared to the ancient Greeks in the amount of gods and in the similarities between the structures of the gods.

The Yoruba have started to become quite popular among Africans all over the world who claim the Yoruba as their family roots and follow the religion and culture of the Yoruba. Many claim that they are part of the Diaspora of the Yoruba as slaves.

The Yoruba originated from a people known as the Oyo who arose and became quite popular by their trading with the Portugues which gave them a large supply of guns. However, they were unable to push back the Fulani who invaded them and pushed much of the Yoruba to the south. In the late 1800's the Yoruba formed a treaty with the Fulani and in 1901 they were colonized by the British. Because of their enmity with the Fulani who are the great Islam evangelists most of the Yoruba do not hold to Islam but instead worship many of the gods and spirits that the Yoruba hold to. Economically the Yoruba primarily engage in agriculture, with about 15% of the people employed as merchants or artists and craftsman.

Historically, the Yoruba were primarily farmers, growing cocoa and yams as cash crops. These are planted in a three-year rotational system, alternating with cassava and a year of diverse crops including maize, peanuts, cotton, and beans. At the end of this three-year cycle the land is left fallow, sometimes for seven years. It is estimated that at one time nearly 70 percent of people participated in agriculture and ten percent each working as crafts people and traders within the towns. Yorubaland is characterized by numerous densely populated urban centers with surrounding fields for farming. The centralization of wealth within cities allowed for the development of a complex market economy which encouraged extensive patronage of the arts.

One of the features that make the Yoruba unique is their tendency to form into large city groups instead of small village groups. Most of the large cities of Nigeria and Benin are inhabited almost solely by Yoruba.

Investigating

1. What kind of climate and landscape do the Yoruba live in?
2. How did the Yorubas adapt to their environment in the past? Think about these aspects: activities, transport, houses, food, and clothes.
3. How has their traditional way of life changed ?
4. Do you think that the family important is to the Yorubas?
5. What does diaspora mean ?
   
6. Who are theYoruba’ gods? What do they represent?
7. How do you think about the Yoruba art ?
8. How do the Yorubas live today?
