How Well Do You Know The 6th Grade Geology

1.

Which of these is not a basic type of rock?

A.

Igneous rock
B.

Sedimentary rock
C.

Volcanic rock
D.

Metamorphic rock

Correct Answer
C. Volcanic rock

Explanation
Volcanic rock is not a basic type of rock because it is a type of igneous rock that forms from lava or magma that has erupted onto the Earth's surface. Igneous rock, sedimentary rock, and metamorphic rock are the three basic types of rocks. Igneous rock forms from the cooling and solidification of magma or lava, sedimentary rock forms from the accumulation and lithification of sediment, and metamorphic rock forms from the transformation of pre-existing rocks due to high pressure and temperature.

The odd term among the following is _______

A.

Diagenesis
B.

Weathering
C.

Erosion
D.

Transport

Correct Answer
B. Weathering

Explanation
Weathering is the odd term among the given options because it refers to the process of breaking down rocks and minerals on the Earth's surface into smaller fragments. Diagenesis, erosion, and transport, on the other hand, are all processes that involve the movement or transformation of these fragmented materials. Weathering is unique in that it specifically focuses on the physical and chemical breakdown of rocks and minerals, while the other options involve the transportation or relocation of these materials.

The following are observed during geological tests except

A.

Color
B.

Taste
C.

Magnetism
D.

Origin

Correct Answer
D. Origin

Explanation
During geological tests, various properties and characteristics of rocks and minerals are examined. Color, taste, and magnetism are physical properties that can be observed and measured during these tests. However, the origin of a rock or mineral is not something that can be directly observed or measured through geological tests. The origin refers to the geological processes and events that led to the formation of the rock or mineral, which is typically determined through other means such as studying the surrounding geological features or analyzing the composition and structure of the rock or mineral.

The unlithified materials often studied by geologist are termed " ________"

A.

Drift
B.

Drift mass
C.

Superficial deposits
D.

Drift deposits

Correct Answer
A. Drift

Explanation
The correct answer is "Drift". This term refers to the unlithified materials that geologists often study. These materials, such as sand, clay, and gravel, are typically deposited by glaciers, rivers, or wind. They are important in understanding the geological history and processes of an area. The other options, "Drift mass", "Superficial deposits", and "Drift deposits", are not commonly used terms in geology to describe these materials.

Which of these methods is not employed in absolute dating?

A.

Uranium-lead dating
B.

Uranium-chlorine dating
C.

Potassium-argon dating
D.

Argon-argon dating

Correct Answer
B. Uranium-chlorine dating

Explanation
Uranium-chlorine dating is not employed in absolute dating. This method does not exist in the field of dating techniques. Uranium-lead dating, potassium-argon dating, and argon-argon dating are all commonly used methods in absolute dating to determine the age of rocks and minerals.

Which of these options is not studied by geologists?

A.

Rivers
B.

Landscapes
C.

Air
D.

Glaciers

Correct Answer
C. Air

Explanation
Geologists study the Earth's solid materials, such as rocks, minerals, and landforms. They also study processes like erosion, plate tectonics, and the formation of landscapes. However, they do not typically study the composition or properties of the Earth's atmosphere, which is the domain of meteorologists and atmospheric scientists. Therefore, the option "Air" is not studied by geologists.

The geologist who postulated the law of superposition is ________

A.

Erik Dawn
B.

John Freud
C.

Nicolas Steno
D.

Ulisse Sina

Correct Answer
C. Nicolas Steno

Explanation
Nicolas Steno is the correct answer because he was a geologist who formulated the law of superposition. The law states that in a sequence of undisturbed sedimentary rock layers, the oldest rocks are found at the bottom while the youngest rocks are found at the top. Steno's contributions to geology also include the principle of original horizontality and the principle of lateral continuity. His work laid the foundation for modern stratigraphy and the understanding of Earth's history.

Who pioneered the process of ordering rock strata?

A.

William Harvey
B.

Peter Davies
C.

William Smith
D.

Jane Thomas

Correct Answer
C. William Smith

Explanation
William Smith is credited with pioneering the process of ordering rock strata. He was a geologist and engineer who developed the concept of stratigraphy, which involves studying and classifying different layers of rock in order to understand the Earth's history and the formation of different geological structures. Smith's work laid the foundation for modern geological mapping and helped establish the principles of relative dating, which are still used by geologists today.

_______ is not a form of geological mapping.

A.

Structural mapping
B.

Surficial mapping
C.

Physical mapping
D.

Stratigraphic mapping

Correct Answer
C. pHysical mapping

Explanation
Physical mapping is not a form of geological mapping. Geological mapping typically involves the study and representation of the composition, structure, and distribution of rocks and geological features in a given area. It focuses on understanding the geological history and processes that have shaped the Earth's surface. Structural mapping involves the analysis of rock structures such as faults and folds. Surficial mapping focuses on the study of surface features like soils, sediments, and landforms. Stratigraphic mapping involves the identification and correlation of rock layers and their ages. However, physical mapping refers to the process of creating physical maps, which are visual representations of geographic features such as landforms, bodies of water, and human-made structures.

The feature of glaciers measurement called?

A.

Glaciology
B.

Geochronology
C.

Paleontology
D.

Glaciochemistry

Correct Answer
C. Paleontology

Explanation
The feature of glaciers measurement is not directly related to glaciology, geochronology, or glaciochemistry. Paleontology, on the other hand, is the study of fossils and can provide valuable information about past glaciers and their history. By studying the fossils found in glacial deposits, paleontologists can understand the age, composition, and changes in glaciers over time. Therefore, paleontology is the most relevant field when it comes to measuring glaciers.
