Geology Chapter I Questions and Answers

1.

What is the study of Earth's physical structures, composition, and history called?
- A.
  
  Meteorology
- B.
  
  Geology
- C.
  
  Astronomy
- D.
  
  Biology
Correct Answer
B. Geology

Explanation
Geology is the study of Earth's physical structures, composition, and history. It explores processes that shaped the Earth, like plate tectonics, volcanism, and erosion.

Rate this question:
2.

Which type of rock is formed from the solidification of molten material?
- A.
  
  Sedimentary
- B.
  
  Metamorphic
- C.
  
  Igneous
- D.
  
  Organic
Correct Answer
C. Igneous

Explanation
Igneous rocks are formed from the solidification of molten material (magma or lava). Examples of igneous rocks include basalt, granite, and obsidian.

Rate this question:
3.

What is the process responsible for the continuous movement and recycling of Earth's lithosphere?
- A.
  
  Photosynthesis
- B.
  
  Evaporation
- C.
  
  Weathering
- D.
  
  Plate tectonics
Correct Answer
D. Plate tectonics

Explanation
Plate tectonics is the process responsible for the continuous movement and recycling of Earth's lithosphere. It involves the movement of Earth's tectonic plates due to convection currents in the mantle.

Rate this question:
4.

Which of the following is NOT an extrusive igneous rock?
- A.
  
  Pumice
- B.
  
  Obsidian
- C.
  
  Granite
- D.
  
  Basalt
Correct Answer
C. Granite

Explanation
Granite is not an extrusive igneous rock. It is primarily composed of large mineral grains and forms beneath the Earth's surface through the slow cooling of magma.

Rate this question:
5.

Which type of rock is formed through the alteration of existing rock by heat, pressure, or chemical reactions?
- A.
  
  Igneous
- B.
  
  Sedimentary
- C.
  
  Metamorphic
- D.
  
  Volcanic
Correct Answer
C. MetamorpHic

Explanation
Metamorphic rocks are formed through the alteration of existing rocks by heat, pressure, or chemical reactions. Examples include marble, slate, and gneiss.

Rate this question:
6.

Which principle states that in a sequence of undisturbed rocks, the oldest rocks are at the bottom and the youngest rocks are at the top?
- A.
  
  Superposition
- B.
  
  Uniformitarianism
- C.
  
  Cross-cutting
- D.
  
  Fossilization
Correct Answer
A. Superposition

Explanation
The principle of superposition states that in a sequence of undisturbed rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. It helps geologists determine relative ages of rocks.

Rate this question:
7.

What is the term for the color of a mineral when it is powdered?
- A.
  
  Streak
- B.
  
  Luster
- C.
  
  Cleavage
- D.
  
  Hardness
Correct Answer
A. Streak

Explanation
The term for the color of a mineral when it is powdered is called streak. It is determined by rubbing the mineral on a porcelain plate and observing the color left behind.

Rate this question:
8.

Which scale is commonly used to measure the magnitude of earthquakes?
- A.
  
  Kelvin scale
- B.
  
  Richter scale
- C.
  
  Mohs scale
- D.
  
  PH scale
Correct Answer
B. Richter scale

Explanation
The Richter scale is commonly used to measure the magnitude of earthquakes. It quantifies the energy released by an earthquake based on the amplitude of seismic waves.

Rate this question:
9.

What is the process of converting loose sediment into sedimentary rock called?
- A.
  
  Erosion
- B.
  
  Weathering
- C.
  
  Fossilization
- D.
  
  Lithification
Correct Answer
D. Lithification

Explanation
Lithification is the process of converting loose sediment into sedimentary rock. It involves compaction, cementation, and hardening of sediment under pressure.

Rate this question:
10.

Which type of rock is primarily composed of organic remains?
- A.
  
  Igneous
- B.
  
  Metamorphic
- C.
  
  Sedimentary
- D.
  
  Sandstone
Correct Answer
C. Sedimentary

Explanation
Sedimentary rocks are primarily composed of organic remains. Fossils and organic matter, such as shells and plant material, accumulate and undergo compaction to form sedimentary rocks.
