  4. D.Kenya
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C Somalia

ምክንያቱ

Ethiopia shares a boundary length of 1,600 km with Somalia, making it the longest shared border among all neighboring countries.

ጥያቄ 3

In which geological era were the ancient crystalline basement complex rocks of Ethiopia formed?

  1. A.The Precambrian Era
  2. B.The Paleozoic Era
  3. C.The Mesozoic Era
  4. D.The Cenozoic Era
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ A The Precambrian Era

ምክንያቱ

The basement complex rocks are the oldest rocks in Ethiopia and were formed during the Precambrian Era, which lasted from 4.5 billion to 600 million years ago.

ጥያቄ 4

What is the highest mountain peak in Ethiopia?

  1. A.Mount Tulu Dimtu
  2. B.Mount Ras Dashen
  3. C.Mount Gughe
  4. D.Mount Chillallo
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B Mount Ras Dashen

ምክንያቱ

Mount Ras Dashen in the Semein mountain system is the highest peak in Ethiopia, standing at an elevation of 4,620 meters above sea level.

ጥያቄ 5

Which specialized sub-branch of physical geography studies the patterns of vegetation growth in relation to climate, soil, and human activities?

  1. A.Zoogeography
  2. B.Geomorphology
  3. C.Phytogeography
  4. D.Climatology
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C Phytogeography

ምክንያቱ

Phytogeography is the branch of biogeography that focuses on the distribution and growth patterns of plants and vegetation.

ጥያቄ 6

During the Triassic Period of the Mesozoic Era, the transgression of the sea into Ethiopia resulted in the deposition of which sedimentary rock?

  1. A.Hintalo limestone
  2. B.Upper Sandstone
  3. C.Adigrat sandstone
  4. D.Trappean basalt
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C Adigrat sandstone

ምክንያቱ

The Adigrat sandstone was the earliest sedimentary rock formed during the Mesozoic Era when the sea began to transgress into southeastern Ethiopia during the Triassic Period.

ጥያቄ 7

Based on Ethiopia's total area (1,106,000 km2) and its boundary length (5,260 km), what is the calculated Area to Boundary (A/B) ratio?

  1. A.1.411
  2. B.210
  3. C.593.5
  4. D.3727
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B 210

ምክንያቱ

Dividing the total area (1,106,000 km2) by the borderline length (5,260 km) gives 210, meaning 1 km of border safeguards about 210 km2 of hinterland.

ጥያቄ 8

Which prominent peak is the highest point in the Southwestern Highlands of Ethiopia?

  1. A.Mount Gughe
  2. B.Mount Abbuye Meda

Mount Gughe, located in the Gamo plateau, rises to 4,200 meters above sea level and is the highest elevation in the Southwestern Highlands.

ጥያቄ 9

Why is the Paleozoic Era unique in the geological history of Ethiopia?

  1. A.It was the era when extensive basaltic lava created the high plateaus.
  2. B.It left a gap in rock formation because intense denudation and peneplanation prevailed.
  3. C.It was marked by rapid marine transgression from the Indian Ocean.
  4. D.It produced the major rift valley faults across the Horn of Africa.
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B It left a gap in rock formation because intense denudation and peneplanation prevailed.

ምክንያቱ

During the Paleozoic Era, the dominant processes in Ethiopia were denudation and peneplanation without any major structural formation, leaving a complete gap in rock formation.

ጥያቄ 10

What does Ethiopia's Boundary-Circumference (B/C) ratio value of 1.411 indicate about the country's shape?

  1. A.The country has a completely elongated and linear shape.
  2. B.The shape deviates by 41% from an assumed theoretical circular shape.
  3. C.The country has an area 1.411 times larger than the African average.
  4. D.The territory forms a perfectly compact circle.
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B The shape deviates by 41% from an assumed theoretical circular shape.

ምክንያቱ

A B/C ratio of 1.411 represents a 0.411 (or 41%) deviation from the ideal value of 1.0, showing that Ethiopia is approximately compact with a 41% divergence from a perfect circle.
