North America has four major deserts: Great Basin, Mohave, Chihuahuan and Sonoran. All but the Sonoran Desert have cold winters. Freezing temperatures are even more limiting to plant life than is aridity, so colder deserts are poorer in both species and life forms, especially succulents.
The four North American deserts
The Great Basin Desert (plate 10) is both the highest-elevation and northernmost of the four and has very cold winters. The seasonal distribution of precipitation varies with latitude, but temperatures limit the growing season to the summer. Vegetation is dominated by a few species of low, small-leafed shrubs; there are almost no trees or succulents and not many annuals. The indicator plant (the most common or conspicuous one used to identify an area) is big sagebrush (Artemisia tridentata), which often grows in nearly pure stands over huge vistas. (Such cold shrub/deserts in the "Old World" are called steppes.)
The Mohave Desert (plate 11) is characterized largely by its winter rainy season. Hard freezes are common but not as severe as in the Great Basin Desert. The perennial vegetation is composed mostly of low shrubs; annuals carpet the ground in wet years. There are many species of these two life forms, but few succulents and trees grow there. The only common tree species is the characteristic joshua tree (Yucca brevifolia), an arborescent (treelike) yucca that forms extensive woodlands above 3000 feet (900 m) elevation.
Though the Chihuahuan Desert (plate 12) is the southernmost, it lies at a fairly high elevation and is not protected by any barrier from arctic air masses, so hard winter freezes are common. Its vegetation consists of many species of low shrubs, leaf succulents, and small cacti. Trees are rare. Rainfall is predominantly in the summer, but in the northern end there is occasionally enough winter rain to support massive blooms of spring annuals. The Chihuahuan Desert is unexpectedly rich in species despite the winter cold.
Answer:
I believe the answer is D
Explanation:
Slave codes were basically laws restricting slaves from having rights to go anywhere without their slave owners, or rights to own firearms. They were scared that the slaves would revolt because there began to be so many slaves being transported.
Answer:
foreign powers were prepared to protect Shanghai itself from the rebels, the understandable suspicion by the Imperial court of European intentions meant that for the time being further support would not be available from foreign governments.
Explanation:
Answer:
A. Six Day War and Yom Kippur War
- After enormous tensions between Israel and its neighbors, the war began in early June 1967 in which Israel occupied the Gaza Strip and the Sinai Peninsula of Egypt, the West Bank and East Jerusalem of Jordan, and the Golan Plateau of Syria in just six days.
- This conflict is known as the Six-Day or the June War and was fought from June 5 to June 10, 1967, between Israel on one side and Egypt, Jordan and Syria on the other.
- The Yom Kippur War, also known as the Ramadan War or the October War was fought between Israel and a coalition of Arab countries led by Egypt and Syria between October 6 and 26, 1973. They invaded the Sinai and the Golan Heights, occupied by Israel in 1967.
B. According to the Camp David Accords, the Israeli Prime Minister has pledged to withdraw from the entire Sinai Peninsula and to recognize the "Land for Peace" principle. The treaty provided for temporary, limited autonomy for the Palestinians as a transitional solution on the way to their own state. But for the sake of general rejection, this did not happen. Only 14 years later, in Oslo, the Palestinians were ready for a similar deal with Israel.
- Politicians from around the world attended the signing of a peace treaty at the White House.
- There was a lack of representatives of the Arab world: above all a representative of the Palestinians.
- The Palestinians opposed the treaty, condemning it as a separate peace and boycotting Egyptian President Sadat. But he did not allow it to be shaken.
E. He was killed.
- Two years after the signing of the Camp David Accords, Egyptian President Anwar Es-Sadat was killed by Islamist opponents of peace in Cairo.
- Still, Camp David is a historic event, and peace between Israel and Egypt continues to this day.
- No love was born of it, but there was a twisted relationship between the two countries.
