B)rock flow
C)weathering
D)cementation

Accepted Answer

C

Question 2

naturally occurring, inorganic substance that does not have orderly arrangement of atoms is called as
A)lava
B)sediment
C)magma
D)meeraloid

Accepted Answer

Mineraloids are naturally occurring, inorganic substances that lack an orderly arrangement of atoms, distinguishing them from true minerals which have a crystalline structure.

Question 3

Small pieces of rocks are called as
A)pebbles
B)particles
C)sediments
D)chips

Accepted Answer

Sediments are small pieces of rocks, minerals, and organic material that are transported and deposited by wind, water, or ice.

Question 4

Igneous rock changes to metamorphic rock by process of
A)magma cooling
B)compaction
C)heat & pressure
D)weathering and erosion

Accepted Answer

The answer of Igneous rock changes to metamorphic rock by...

Question 5

The method of rock forming is called as
A)weathering cycle
B)rock cycle
C)magma cycle
D)rock formation

Accepted Answer

The rock cycle is the correct term for the process of rock formation and transformation, involving the creation, alteration, and recycling of rocks through various geological processes like weathering, erosion, sedimentation, and metamorphism.

Question 6

Which classification of rock is not found in rock cycle ?
A)cemented rock
B)metamorphic rock
C)semdimentary rock
D)igneous rock

Accepted Answer

Cemented rock is not a classification used in the rock cycle. The rock cycle typically includes metamorphic, sedimentary, and igneous rocks.

Question 7

Igneous rocks are formed by
A)weathering and erosion
B)heat and pressure
C)compaction and cementation
D)cooling of magma

Accepted Answer

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

Question 8

Large inverted mushroom-shaped intrusions that sag down in the middle due to dense rocks are called as
A)laccoliths
B)lopoliths
C)balnoliths
D)dikes

Accepted Answer

Lopoliths are the large, inverted mushroom-shaped intrusions that sag down in the middle due to the weight of dense rocks.

Question 9

How thick is the crust of the earth ?
A)about 4 miles
B)about 4 km
C)about 40 km
D)about 400 km

Accepted Answer

The average thickness of the Earth's crust is about 40 km. However, this thickness varies, being thinner under the oceans (about 5-10 km) and thicker under the continents (about 30-50 km).

Question 10

What drives the internal heat of earth ?
A)volcanoes
B)radioactive elements
C)solar energy
D)ocean hides

Accepted Answer

The internal heat of the Earth is primarily driven by the decay of radioactive elements within its core and mantle, generating heat through nuclear reactions.

Question 11

Which will be the parental rock for metamorphic rock ?
A)sedimentary
B)igneous
C)metamorphic
D)all of these

Accepted Answer

Metamorphic rocks can form from sedimentary, igneous, or even other metamorphic rocks as parent rocks. The process involves the alteration of these rocks by heat, pressure, or chemically active fluids, leading to a new rock type.

Question 12

Type of texture formed due to rapid cooling is
A)aphanitic
B)phaneritic
C)course grained
D)none of these

Accepted Answer

Aphanitic texture is characteristic of volcanic rocks, which cool rapidly on the Earth's surface, resulting in fine-grained minerals that are often too small to see with the naked eye.

Question 13

Crust and lithosphere are having same meaning.
A)true
B)false
C)none
D)none.

Accepted Answer

The crust and lithosphere are not the same; the crust is the outermost layer of the Earth, while the lithosphere includes the crust and the upper part of the mantle.

Question 14

The curst of earth is static and stable.
A)true
B)false
C)none
D)none.

Accepted Answer

The crust of the Earth is not static and stable; it is dynamic and constantly changing due to plate tectonics, volcanic activity, erosion, and other geological processes.

Question 15

The earth's external heat engine is not responsible for
A)climate
B)erosion
C)tides
D)winds

Accepted Answer

The earth's external heat engine, powered by solar energy, influences climate, erosion, and winds by driving atmospheric and oceanic circulation. Tides, however, are caused by the gravitational pull of the moon and the sun, not by the earth's external heat engine.

Question 16

The lithosphere is approximately thick.
A)50-100 km
B)100-200 km
C)5-10 km
D)1-2 km

Accepted Answer

The lithosphere, which includes the Earth's crust and the uppermost mantle, is approximately 50-100 km thick.

Question 17

The element which is having highest volume per cent in the continental crust of earth is
A)aluminium
B)oxygen
C)iron
D)sodium

Accepted Answer

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

Question 18

What is the most common structural element of group silicate mineral ?
A)a silicon ? aluminium tetrahedron
B)a silicon ? nitrogen tetrahedron
C)a silicon ? oxygen tetrahedron
D)a silicon ? oxygen octahedron

Accepted Answer

The most common structural element of group silicate minerals is a silicon-oxygen tetrahedron, where a silicon atom is surrounded by four oxygen atoms in a tetrahedral arrangement.

Question 19

Diamond is having hardness number
A)10
B)7
C)1
D)2

Accepted Answer

Diamond is known for being the hardest natural material and is rated 10 on the Mohs scale of mineral hardness.

Question 20

Plutonic type of rocks generally shows
A)fine grained texture
B)course grained texture
C)both b
D)none

Accepted Answer

The answer of Plutonic type of rocks generally shows
A)fine grained...
