The western side of North America, Erem Alaska to Fanama, is occupied by young mountains which are part of the Circum-Pacific System, The Rocky Mountains of the United States, Canada, and Alaska are a major constituent, as are the Cascades, Sierra Nevada. Within this area of young fold mountains the a are high plateaux, auc
·as the High Plateau of Colorado, the Columbia Plateau and the plateau of Mexicos regione of.. block mountains, such as the Great Basin and a few plains, such as the Valley of California. In the northern part of the continent lies the Canadian Shield, which reaches into the United States of America. The Appalachians, which have an outlier west of the Mississippi River, are old, highly eroded mountains, Great interior plains reach from the Arctic Ocean in the north all the way into Texas. The Gulf Atlantic Coastal Plain is the most extensive coastal plair in the world.
B) (1) Describe how lcess is formed,
Ans. LOESS is wind borne deposit accumulated outside)
the desert areas, Wind carries fine dust particles beyond the desert margins and drop them on neighbouring land areas. In Europe, loess is known as limon and in the United Stater it is termed adobe.
Outline the influences of loses on human activities,
Loess is porous, Tabre and easily eroded by rivers. In northern part of China, the loess. deposits reach thickness of several hundred feet, obliterating the former topography and. forma a low plateau of buff-coloured,
unconsolidated and highly porous deposits, in which the streams and vivers cut deep gorges. The soils can support heavy crops if adequately supply with moisture, But the Loess Plateau of North China is an area of erratic and low. amount of rainfall. Irrigation is difficult because the river flows at a much lower level. than the neighbouring Land. Nevertheless many of the 3cess hills are terraced for: crope, Irrigation is difficult because the xivers flow at a much Lower level than the neighbouring lend. Roade are out deep. into the plateau surface and people live in house白 carved out of the Loese cliffe
(iii)On a world map, locate the areas where Loess
can be found.
.1
There are less deposits in Central Tope and parts of the Great Plain of North America) and the Pampas of South America. They are,,, however, not of great thickness. They are generally fertile and as they do not suffer from the lack of available water, can be used for commercial cereal farming or pastoral
activities.
