Gaaffii 1

According to the Big Bang theory presented in the textbook, about how many billion years ago was the Earth formed from a mixture of gas and dust particles?

A.4.5 billion years ago
B.10.0 billion years ago
C.15.5 billion years ago
D.20.0 billion years ago

Deebii fi sababa agarsiisi

Deebii: A 4.5 billion years ago

Sababa

The textbook states that Earth was created from the mixture of gas and dust particles moving in space around the Sun about 4.5 billion years ago.

Gaaffii 2

Which relative dating principle states that in an undisturbed sequence of sedimentary rock layers, the overlying bed is younger than the underlying rock?

A.Principle of original horizontality
B.Principle of superposition
C.Principle of cross-cutting relationships
D.Principle of radioactive decay

Deebii fi sababa agarsiisi

Deebii: B Principle of superposition

Sababa

The principle of superposition asserts that in an undisturbed sequence of sedimentary layers or lava flows, each overlying bed is younger than the rock layer beneath it.

Gaaffii 3

What is the deepest point in the world, located in the Pacific Ocean?

A.Challenger Deep
B.Puerto Rico Trench
C.Java Trench
D.South Sandwich Trench

Deebii fi sababa agarsiisi

Deebii: A Challenger Deep

Sababa

The deepest point in the world is the Challenger Deep within the Mariana Trench in the Pacific Ocean, reaching a depth of about 10,924 meters.

Gaaffii 4

In the ancient Greek climate classification, which zone represents the warm tropical area south of the Mediterranean Sea?

A.Frigid Zone
B.Torrid Zone
C.Temperate Zone
D.Polar Zone

Deebii fi sababa agarsiisi

Deebii: B Torrid Zone

Sababa

The ancient Greeks used the Torrid Zone to represent the tropics, which were the warm areas south of the Mediterranean Sea.

Gaaffii 5

What is the name of the early supercontinent that gathered together at about 750 Ma before the formation of Pangaea?

A.Laurasia
B.Gondwanaland
C.Rodinia
D.Baltica

Deebii fi sababa agarsiisi

Deebii: C Rodinia

Sababa

According to the textbook, the initial landmasses gathered to form the early Neoproterozoic supercontinent called Rodinia at about 750 Ma.

Gaaffii 6

During radioactive decay, what stable daughter isotope does Potassium-40 (⁴⁰K) convert into?

A.Argon-40 (40Ar)
B.Nitrogen-14 (14N)
C.Lead-206 (206Pb)
D.Strontium-87 (87Sr)

Deebii fi sababa agarsiisi

Deebii: A Argon-40 (40Ar)

Sababa

The decay table shows that the parent isotope Potassium-40 (⁴⁰K) decays into the daughter isotope Argon-40 (⁴⁰Ar) with a half-life of 1.25 billion years.

Gaaffii 7

What is the approximate ratio of land to ocean in the Southern Hemisphere?

A.1:1.5
B.1:4
C.4:1
D.1:1

Deebii fi sababa agarsiisi

Deebii: B 1:4

Sababa

The ratio of land to ocean is about 1:1.5 in the Northern Hemisphere, but it is 1:4 in the Southern Hemisphere.

Gaaffii 8

According to the Köppen climate classification, which temperature condition defines a Tropical climate (Type A)?

A.All months have an average temperature above 18 degrees Celsius
B.The warmest month has an average temperature below 10 degrees Celsius
C.The coldest month average drops below -30 degrees Celsius
D.Average temperature remains below freezing throughout the entire year

Deebii fi sababa agarsiisi

Deebii: A All months have an average temperature above 18 degrees Celsius

Sababa

In Köppen's system, a Tropical climate (A) is defined by all twelve months having an average temperature above 18 degrees Celsius (64 degrees Fahrenheit), meaning there is no real winter.

Gaaffii 9

A student in Addis Ababa analyzes a rock sample in a laboratory. The test shows that 25% of the original parent isotope remains and 75% has converted into daughter isotopes. How many half-lives have passed?

A.1 half-life
B.2 half-lives
C.3 half-lives
D.4 half-lives

Deebii fi sababa agarsiisi

Deebii: B 2 half-lives

Sababa

After 1 half-life, 50% of the parent isotope remains. After 2 half-lives, the parent isotope is halved again to 25%, while the daughter isotope reaches 75%.

Gaaffii 10

During which geological era did Pangaea split into Laurasia and Gondwanaland, accompanied by the dominance of dinosaurs?

A.Precambrian era
B.Paleozoic era
C.Mesozoic era
D.Cenozoic era

Deebii fi sababa agarsiisi

Deebii: C Mesozoic era

Sababa

The Mesozoic era (250 to 70 Ma) is known as the age of dinosaurs and was the time when Pangaea split into Laurasia and Gondwanaland.
