1. Petrology is the study of__?
[A] Soils
[B] Rocks
[C] Oceans
[D] Mountains
Show Answer

2. What does an “Epicenter” of an earthquake means ?
[A] point of initial rupture
[B] point at ground level directly above the point of initial rupture
[C] Circle of earthquake disturbances
[D] geographical area affected by earthquake
Show Answer
Correct Answer: B [point at ground level directly above the point of initial rupture]
Notes:
The point at ground level directly above the point of initial rupture in an earthquake is known as the epicenter. This is the point on the surface of the Earth that is closest to the location of the earthquake’s initial rupture, or focus. The epicenter is typically determined by seismologists using data from seismographs, which measure the intensity and duration of the earthquake at various locations. The epicenter is an important point of reference for understanding the characteristics of an earthquake, including its magnitude and the distribution of its effects.
3. Which of the following African Country was formerly known as Nyasaland?
[A] Tanzania
[B] Malawi.
[C] Mozambique
[D] Botswana
Show Answer
Correct Answer: B [Malawi.]
Notes:
Malawi is formerly known as Nyasaland. Malawi is a landlocked country in southeastern Africa. It has a topography of highlands split by the Great Rift Valley and enormous Lake Malawi.
4. Which of the following is correct definition of the Lacustrine deposits?
[A] sedimentary rock formations in the bottom of ancient lakes
[B] metamorphic landscape formed on the deep ocean floor
[C] ring shaped coral reef that encircles a lagoon partially or completely
[D] natural areas in which the ground is covered with salt and other minerals
Show Answer
Correct Answer: A [sedimentary rock formations in the bottom of ancient lakes]
Notes:
Lacustrine deposits are sedimentary rock formations which formed in the bottom of ancient lakes. A common characteristic of lacustrine deposits is that a river or stream channel has carried sediment into the basin.
5. Consider the diagrams below:
The above diagrams show the position of the Earth, the Moon and the Sun where
[A] Only situation A explains the spring tides.
[B] Only situation B explains the spring tides.
[C] Both situations A and B explain the spring tides.
[D] None of the above
Show Answer
Correct Answer: C [Both situations A and B explain the spring tides.]
Notes:
Spring tide is a tide in which the difference between high and low tide is the greatest. Spring tides occur when the Moon is either new or full, and the Sun, the Moon, and the Earth are aligned. When this is the case, their collective gravitational pull on the Earth’s water is strengthened. Compare neap tide.
6. Which of the following parent rocks is not responsible for Karst topography?
[A] Granite
[B] Calcium carbonate
[C] Gypsum
[D] Dolomite
Show Answer
Correct Answer: A [Granite]
Notes:
Karst topography is a result of presence of soluble rock materials beneath the surface layer which results in the wash away of the soluble material by moving water beneath the surface such that the top surface layer becomes weak.
7. Baffin Island is located in which country?
[A] Bahamas
[B] United States of America
[C] Japan
[D] Canada
Show Answer
Correct Answer: D [Canada]

8. Which Era continues even today?
[A] Cenozoic
[B] Mesozoic
[C] Paleozoic
[D] Neoproterozoic
Show Answer
Correct Answer: A [Cenozoic]
Notes:
The Cenozoic Era began 65 million years ago and continues even today.
9. What is a major factor in determining the properties of the rocks?
[A] Carbon
[B] Hydrogen
[C] Oxygen
[D] Silica
Show Answer
Correct Answer: D [Silica]
Notes:
The proportion of silica in rocks and minerals is a major factor in the determination of the rocks and their properties.
