Igneous rocks are formed through the cooling and solidification of magma or lava.

Question 2

Granite is an example of
A)aqueous rocks
B)sedimentary rocks
C)metamorphic rocks
D)igneous rocks

Accepted Answer

Granite is an example of igneous rocks, which are formed from the solidification of molten rock material.

Question 3

Solidification of molten magma at the surface of the earth results in the formation of
A)sedimentary rock
B)basalt and traps
C)granite
D)metamorphic rock

Accepted Answer

Solidification of molten magma at the surface of the Earth typically results in the formation of basalt and traps, which are types of igneous rocks.

Question 4

.Solidification of molten magma within the earth's crust results in the formation of
A)sedimentary rock
B)basalt and trap
C)granite
D)metamorphic rack

Accepted Answer

Granite is an example of an intrusive igneous rock that forms from the solidification of molten magma within the Earth's crust.

Question 5

Sedimentary rocks are formed due to
A)solidification of molten mass
B)gradual deposition of materials like sand, clay, generally by setting water
C)alteration of original stones under heat and pressure
D)none of the above

Accepted Answer

Sedimentary rocks are formed through the gradual deposition and accumulation of material such as sand, silt, and clay, often in water bodies. This process involves the compaction and cementation of these materials over time.

Question 6

Under metamorphism, which of the following changes is correct?
A)granite changes to gnesis.
B)trap and basalt change into laterite.
C)limestones change into marble.
D)all the above

Accepted Answer

Metamorphism is the process of changing the texture and composition of rocks due to heat and pressure. In metamorphism, granite changes to gneiss, trap and basalt change into laterite, and limestones change into marble.

Question 7

Granite has
A)crystalline, glossy and fused texture
B)foliated structure
C)layers of different compositions
D)none of the above

Accepted Answer

Granite is an igneous rock with a crystalline, glossy, and fused texture.

Question 8

The principal constituent of argillaceous rock is
A)Sand
B)lime
C)clay
D)all the above

Accepted Answer

Argillaceous rocks are primarily composed of clay minerals, which give them their characteristic properties and name.

Question 9

Laterite is chemically classified as
A)calcareous rock
B)siliceous rock
C)metamorphic rock
D)argillaceous rock

Accepted Answer

Laterite is rich in iron and aluminum, formed in hot and wet tropical areas, and is classified as an argillaceous rock due to its clay-like properties.

Question 10

Which of the following is an example of siliceous rock?
A)granite
B)gnesis
C)quartzite
D)all the above

Accepted Answer

Quartzite is an example of siliceous rock, which is primarily composed of silica or silicon dioxide (SiO2). Granite and gneiss, although they can contain significant amounts of silica, are not classified as siliceous rocks; granite is an igneous rock, and gneiss is a metamorphic rock.

Question 11

Marble is an example of
A)aqueous rock
B)metamorphic rock
C)sedimentary rock
D)igneous rock

Accepted Answer

Marble is a metamorphic rock formed from the recrystallization of limestone under high temperature and pressure conditions.

Question 12

Slate is used for
A)building walls
B)road metal
C)manufacture of cement
D)roofing

Accepted Answer

Slate is commonly used for roofing due to its durability, water resistance, and aesthetic appeal.

Question 13

Which one of the following takes polish very well?
A)basalt and trap
B)granite
C)sandstone
D)quartzite

Accepted Answer

Granite takes polish very well due to its hardness and interlocking crystal structure, making it a popular choice for countertops and decorative stone.

Question 14

The colour of granite is
A)grey
B)green
C)brown
D)all of these

Accepted Answer

Granite is a natural stone and comes in a variety of colors, including grey, green, and brown, among others. The color variation is due to the mineral composition in the granite.

Question 15

A fine grained granite
A)can be polished well
B)can be used for exterior facing of buildings
C)offers higher resistance to weathering
D)all of the above

Accepted Answer

Fine-grained granite can be polished well, making it aesthetically pleasing for various applications including exterior facing of buildings. Its compact grain structure also offers higher resistance to weathering, making it durable for outdoor use.

Question 16

Siliceous sand subjected to metamorphic action is known as
A)laterite
B)murram
C)quartzite
D)dolomite

Accepted Answer

Siliceous sand, when subjected to metamorphism, transforms into quartzite, a hard, non-foliated metamorphic rock primarily composed of quartz.

Question 17

When quarrying is to be done in hard and compact rocks, the usual method employed is
A)wedging
B)using channeling machine
C)blasting
D)all of the above

Accepted Answer

Blasting is the most common method used for quarrying hard and compact rocks due to its efficiency in breaking down large volumes of rock quickly.

Question 18

Quarrying by using channeling machine is employed for quarrying in
A)soft rock
B)hard rock
C)sandstones
D)all the above

Accepted Answer

The answer of Quarrying by using channeling machine is employed...

Question 19

Heating technique of breaking rocks is suitable if the aim is to get
A)aggregates
B)slabs
C)building blocks
D)none of the above

Accepted Answer

Heating technique of breaking rocks is suitable for producing aggregates because it involves thermal expansion and rapid cooling, which fractures the rock into smaller, irregular pieces ideal for use as aggregates.

Question 20

The process of taking out stones of various sizes from natural rock is known as
A)dressing
B)seasoning
C)polishing
D)quarrying

Accepted Answer

Quarrying is the process of extracting stones of various sizes from natural rock formations, which involves cutting, digging, or blasting to obtain stone from a quarry.
