9when the equator crosses africa in 2 places it results in
climatic and physical conditions
10what occur during landforms
material and energy flow
11the African alpine include
the atlas mountain
12the atlas mountain
extends from Morocco to Tunisia 2000km long
13The Africa massive includes
The Savannah the Sahara and the tropical Forrest and the sahel
14the sahara
92000 km, from the atlantic coast to the red sea

17reg
pavement of pebbles on top of a vast flat surface sheets of sand
18the sahel
means shore, semi arid of north africa located south of the sahara
19countries of the sahel
Mauritania Senegal mali Niger Nigeria burkina Faso Chad Sudan Eritrea
20the sahel lands are
grasslands and savanna lands
21the savanna
is a transitional season between the sahel land the rainforest. has a few trees and shrubs
22shedding
maragef. it also reduces water loss
232 types of savanna
woodland ( which are widly spaced bc of soil moisture) and grassland ( thorn tree tall grass)
24tropical rainforest
occur both in north and south of the equator. those which are found near the equator are called equatorial rainforests.
25what trees dominate the rainforest
broadleaf evergreen trees
26the congo basin consists
equatorial Guinea, Cameroon central African republic, republic of Congo, democratic republic of Congo, and gabon.
27others might include in the tropical rainforest
Madagascar, ivory coast, and Ghana
28the trees in the rainforest are
closely spaced, might be 25-35 meters
29what types of characteristic do the rainforest plants havewjay(the leaf type)
evergreen wit dark green, leathery large leaves. epiphytic and herbaceous plants and vines( lianes) and ferns
30the rainforest climate
2000 to 2250 mmr rainfall, temperature and humidity are relatively high.
31why is decomposition high in the rainforest
bc of high temperatures and moisture
32what happens bc of heavy rain fall and frequent in the rainforest
the soils are subjects of leaching and chemical weathering.
33landforms
physical features of the earth's surface that form terrain of an area.
343 major types of landforms
mountains, plateaus and planes
35minor landforms
hills, gorges valleys and basins.
36how are rift valleys formed
faulting
37graben
it is an elongated block of the earth's crust lying bn two faults and lies downward relative to the blocks on either side of it.
38the rift valley extends from
Ethiopia in the north to Malawi's in the south
39the rift valley begins
red sea to lake victoria where it subdivide into east and west segment and continues southward through lake Malawi to Mozambique. it is estimated to be 5600 km. the average width from 32 -80km
40the great rift valley splits the Ethiopian highlands into
northwestern and south eastern
41lake victoria
1134 meters above sea level, 68000 sq² largest lakes in africa. it occupies a depression between the eastern and western rifts formed by the uplifts to the lifts to wither side.
42the Ethiopian and eritrean highlands
it is set on high plateau with massive central highland complex mountains divided by the deep great rift valley.
43the wide diversity of terrain produces regional variation in
climate, natural vegetation, soil compost and settlements patters.
44southern africa platform
south of congo and Tanzania, it includes escarpments, mountains, grassland and desert landscape. the tropic of capricorn passes through the middle. the southern portion is in the temprates.
45ukhalamba/ drakensberg
most known escarpment, 3000 m above sea level
46kalahri
Botswana, arid mixture of grassland and sand. it is home to game reserves and national park.
47Namib desert
affected by the cold ocean current benguela, it was also formed by it
48highveld
inland plateau, slopes gently downwards and its surrounding ded by the great karoo in the south, kalahari desert in the west and the bushels in the north. it is home to commercial farming also for metropolitan cities
49the Greeks were the first to classify the hemisphere into 3 zones
torrid(tropical), temperate, frigid
50class names for classification systems based on weather patterns include
geographical names like polar, tropical, continental and marine.
