Question 1

The branch of geology which deals with study of chronology of the earth's past events is called as
A)historical geology
B)structural geology
C)physical geology
D)none of the above

Accepted Answer

Historical geology focuses on understanding Earth's past through studying rock formations, fossils, and geologic events to reconstruct the planet's history.

Question 2

The branch of geology which deals with study of uppermost layers of earth's crust is known as
A)petrology
B)hydrogeology
C)pedology
D)geomorphology

Accepted Answer

Pedology is the study of soils in their natural environment. It is a branch of geology that deals with the study, description, and systematic classification of soil. This includes understanding the formation, distribution, and classification of soils, as well as their physical, chemical, biological, and fertility properties in relation to their management for agriculture, forestry, or land conservation.

Question 3

Rocks which are formed from weathering products of preexisting rocks deposited near earth's surface are called as
A)Igneous rocks
B)Sedimentary rocks
C)Metamorphic rocks
D)None of the above

Accepted Answer

Sedimentary rocks are formed from the accumulation and lithification of material that has been eroded, transported, and deposited by water, wind, or ice from preexisting rocks. This process includes weathering, erosion, transportation, deposition, and lithification.

Question 4

In relative proportion of rocks by weight percentage which type of rocks are having maximum percentage ?
A)Igneous rocks
B)Sedimentary rocks
C)Metamorphic rocks
D)None of the above

Accepted Answer

Igneous rocks form the majority of the Earth's crust, making up about 95% of the total volume of the Earth's crust. This is because they originate from the solidification of magma or lava, which constitutes the bulk of the planet's mantle and crust.

Question 5

In relative proportion of rocks by volume percentage which type of rocks are having maximum percentage ?
A)Igneous rocks
B)Sedimentary rocks
C)Metamorphic rocks
D)None of the above

Accepted Answer

Sedimentary rocks are the most abundant type of rock on Earth, accounting for about 75% of the Earth's crust.

Question 6

Rocks which are made up of one mineral are called as
A)monomineralic
B)polymineralic
C)both
D)none of these

Accepted Answer

Monomineralic rocks are composed of a single type of mineral, distinguishing them from polymineralic rocks, which are made up of multiple types of minerals.

Question 7

Large magnitude or sudden events that modify the pre-existing landscapes is known as
A)catastrophism
B)metamorphism
C)physimorphism
D)none of these

Accepted Answer

Catastrophism is the theory that Earth's landscapes have been shaped primarily by great catastrophes, such as earthquakes, floods, and volcanic eruptions, rather than by gradual processes.

Question 8

Approximately % of sun's heat is absorbed by land, sea or the atmosphere ?
A)40
B)20
C)10
D)60

Accepted Answer

Approximately 60% of the sun's heat is absorbed by the land, sea, or the atmosphere, with the remainder being reflected back into space. This absorption is crucial for maintaining the Earth's climate and supporting life.

Question 9

Element which constitute earth crust with maximum volume per cent is
A)oxygen
B)potassium
C)sodium
D)silicon

Accepted Answer

Oxygen is the most abundant element in the Earth's crust by volume, making up about 46.6% of the crust.

Question 10

About % of earth's surface is occupied by the oceanic basins.
A)60
B)40
C)10
D)none of the above

Accepted Answer

Approximately 71% of the Earth's surface is covered by water, with the vast majority being oceanic basins. The closest option provided is 60%, making it the correct choice.

Question 11

% of continental crust is occupied by oceanic water.
A)10
B)60
C)40
D)50

Accepted Answer

The answer of % of continental crust is occupied by...

Question 12

The study of rocks in the laboratory as hand specimens with a view to analyse and discuss their texture, mineral composition, chemical composition is called as
A)petrography
B)hydrogeology
C)pedology
D)any of the above

Accepted Answer

Petrography is the branch of geology concerned with the description and classification of rocks, especially by microscopic examination of thin sections. It focuses on analyzing the texture, mineral composition, and chemical composition of rocks.

Question 13

The physical property of mineral by which minerals are identified on account of its colour of the powder form is called as
A)colour
B)luster
C)streak
D)none of these

Accepted Answer

Streak is the physical property of a mineral that describes the color of its powder form. It is a useful diagnostic tool in mineral identification because the streak color of a mineral is usually consistent regardless of the mineral's external color or weathering surface.

Question 14

Lusture shown by broken glass is known as
A)metallic
B)sub-metallic
C)silky
D)none of the above

Accepted Answer

The luster shown by broken glass does not fall into the categories of metallic, sub-metallic, or silky. These terms are typically used to describe the appearance of minerals or metals, not glass. Glass, when broken, has a vitreous luster, which is not listed among the options provided.

Question 15

Lusture shown by fibrous minerals is known as
A)pearly
B)vitreous
C)dull
D)none of these

Accepted Answer

The answer of Lusture shown by fibrous minerals is known...

Question 16

Which mineral generally shows one set of cleavage ?
A)feldspar
B)mica
C)calcite
D)fluorite

Accepted Answer

Mica is known for its perfect basal cleavage, which allows it to be split into very thin sheets. This is a distinctive property of mica, differentiating it from the other minerals listed.

Question 17

Two set of cleavage is seen in
A)feldspar
B)mica
C)calcite
D)fluorite

Accepted Answer

The answer of Two set of cleavage is seen in
A)feldspar
B)mica
C)calcite
D)fluorite...

Question 18

Talc is showing which type of luster ?
A)pearly
B)silky
C)dull
D)resinous

Accepted Answer

Talc often exhibits a pearly luster, which is characteristic of its appearance, especially on cleavage faces.

Question 19

Quartz is showing which type of luster ?
A)metallic
B)non-metallic
C)peraly
D)none of these

Accepted Answer

The answer of Quartz is showing which type of luster...

Question 20

Asbestos is showing which type of luster ?
A)vitreous
B)metallic
C)non-metallic
D)silky

Accepted Answer

Asbestos fibers typically exhibit a silky luster due to their fine, fibrous composition, which gives them a soft, silk-like sheen.
