Question 1
1 / -0

The elements in the earth's crust are rarely found exclusively but are usually combined with other elements to make various substances, which are recognised as minerals but sometimes single element minerals are also found. Which of these is a single element mineral?

A
Feldspar

B
Olivine

C
Mica

D
Pyroxene

E
Graphite

Solution

Graphite is a single element mineral found in the earth's crust.
Question 2
1 / -0

Which of the following is incorrect?

A
The basic source of all minerals is the hot magma in the interior of the earth.

B
When magma cools, crystals of minerals appear and a systematic series of minerals are formed in sequence to solidify, so as to form rocks.

C
A mineral is a naturally occurring organic substance, having an orderly atomic structure and a definite chemical composition and physical properties.

D
All of the above statements are incorrect.

E
None of the above statements is incorrect.

Solution

This is correct, as this statement is incorrect. A mineral can be organic as well as non organic. Thus, this is incomplete and incorrect.
Question 3
1 / -0

Which of the following is correct?

A
Feldspar has light cream to salmon pink colour and is used in ceramics and glass making.

B
Pyroxene is white or colourless and used in radio and radar, and is one of the most important components of granite.

C
Quartz is commonly found in meteorites and is in green or black in colour.

D
Olivine is commonly found in igneous and metamorphic rocks, and is used in electrical instruments.

E
Mica is in green or black colour, and is used in asbestos industry.

Solution

This is correct. Half of the earth's crust is composed of feldspar. It has light cream to salmon pink colour and is used in ceramics and glass making.
Question 4
1 / -0

Which of the following types of rocks are formed by the process of lithification?

A
Igneous rocks

B
Sedimentary rocks

C
Metamorphic rocks

D
All types of rocks

E
Sedimentary and Igneous rocks

Solution

Rocks on the earth's surface break up into various sizes and fragments, and are deposited by different exogenous agencies. These deposits through compaction turn into rocks. This process is called lithification. Sedimentary rocks undergo the process of lithification.

Question 5

1 / -0

Match the column I sedimentary rock with column II mode of formation:

Column I	Column II
1. Sandstone	a. Chemically formed
2. Chalk	b. Mechanically formed
3. Potash	c. Organically formed

1 - a, 2 - b, 3 - c

1 - b, 2 - c, 3 - a

1 - c, 2 - b, 3 - a

1 - a, 2 - c, 3 - b

1 - c, 2 - a, 3 - b

Solution

This is the correct answer. Sandstone is a mechanically formed sedimentary rock. Chalk is an organically formed sedimentary rock. Potash is a chemically formed sedimentary rock.

Question 6
1 / -0

Which of the following statements is/are correct?
a. The minerals that contain metal content are called metallic minerals.
b. Iron and other metals often mixed with iron to form various kinds of steel are called ferrous metals.
c. Platinum is a precious metal.

A
Only a

B
Only b

C
Only c

D
Only a and c

E
All of these

Solution

This is the correct answer, as all the statements are correct.
Question 7
1 / -0

Cement is a mixture of

A
metallic minerals

B
ferrous metals

C
non ferrous metals

D
non metallic minerals

E
none of these

Solution

This is the correct answer. Cement is a mixture of non-metallic minerals.
Question 8
1 / -0

Which of the following sets comprises of non ferrous metals?

A
Copper, lead, zinc, tin, aluminium

B
Copper, lead, sulphur, tin, aluminium

C
Copper, lead, zinc, phosphate, aluminium

D
Copper, sulphur, phosphate, tin, aluminium

E
Copper, lead, sulfur, phosphate, nitrate

Solution

Copper, lead, zinc, tin, aluminium are all non ferrous metals.
Question 9
1 / -0

Which of the following has the maximum resistance to being scratched?

A
Talc

B
Gypsum

C
Capsite

D
Feldspur

E
Topaz

Solution

Among the given minerals topaz is the hardest. Hence, resistant to being scartched.
Question 10
1 / -0

Which of the following minerals is used in making jewellery?

A
Olivine

B
Mica

C
Amphibole

D
Feldspur

E
Pyroxene

Solution

Magnesium, iron and silica are major elements of olivine. It is used in jewellery.
Question 11
1 / -0

An arrangement of layers or lines in minerals or grains in metamorphic rocks is called as

A
dynamic metamorphism

B
thermal metamorphsim

C
foliation

D
banding

E
lithification

Solution

In the process of metamorphism in some rocks grains or minerals get arranged in layers or lines. Such an arrangement of minerals or grains in metamorphic rocks is called foliation or lineation.
Question 12
1 / -0

Which of the following is a process by which already consolidated rocks undergo recrystallisation and reorganisation of materials within original rocks?

A
Metamorphism

B
Banding

C
Foliation

D
Lithification

E
Transformation

Solution

Metamorphism is a process by which already consolidated rocks undergo recrystallisation and reorganisation of materials within original rocks.
Question 13
1 / -0

Which of the following is not a sedimentary rock?

A
Geyserite

B
Halite

C
Coal

D
Basalt

E
Shale

Solution

Basalt is an igneous rock.
Question 14
1 / -0

Which of the following is a science of rocks?

A
Pedology

B
Seismology

C
Petrology

D
Archaeology

E
Geology

Solution

Petrology is the science of rocks. A petrologist studies rocks in all their aspects viz., mineral composition, texture, structure, origin, occurrence, alteration and relationship with other rocks.
Question 15
1 / -0

Which of the following statements about the nature of minerals is incorrect?

A
Some minerals have characteristic colour determined by their molecular structure and some minerals are coloured by impurities.

B
Lustre is the appearance of a material without regard to its colour.

C
External crystal form of a mineral is determined by the internal arrangement of the molecules.

D
Cleavage is quality of a mineral with the internal molecular arrangement, so complex that there are no planes of molecules and the crystal will break in an irregular manner.

E
Hardness of a mineral is measured by its relative resistance to being scratched.

Solution

This is incorrect. Cleavage is the tendency to break in given directions producing relatively plane surfaces as a result of internal arrangement of the molecules. It may cleave in one or more directions and at any angle to each other.
