Indian Geography Chapter 2: EARTH
Q1: The upper layer of the Earth’s crust is called as
athenosphere
mantle
barysphere
lithosphere
Q2: upper part of the earth's crust is called as
SiAl
SiMa
both
NiFe
Q3: lower part of the Earth's crust is
SiAl
SiMa
both
NiFe
Q4: Core is also called the
SiMa
SiAl
both
NiFe
Q5: Which is true ?
Continents [SiAl – Silica + Aluminum] are granite
oceans are basaltic
both
none
Q6: Which is true ?
Outer core is liquid
inner core is solid
both
none
Q7: Which is true ?
Iron has highest composition in earth
oxygen has highest composition in Earth's crust
Continental crust is light and oceanic is heavy.
all
Q8: Igneous rocks:
Formed by solidification of magma or lava.
Don’t have strata or layers
Don’t have fossils.
all
Q9: Which is true ?
non crystalline if volcano burst out and cools at the surface [e.g.: basalt]
crystalline if volcano doesn’t burst and cools inside surface [ e.g.: granite]
both a and b
none
Q10:these are formed after the magma has cooled beneath the Earth’s surface
volcanic rocks
plutonic rocks
both
none
Q11: the molten rocks pour out of the surface as lava. This cools faster at the surface and crystals formed are small. and are called
volcanic rocks
plutonic rocks
both
none
Q12: Sedimentary rocks:
Formed when sediments compact under pressure lose fluid and become solid called lithification
They are non crystalline.
Have fossils and strata.
all
Q13: Sedimentary rocks are of types
mechanically
organically
chemically
all
Q14: Metamorphic rocks
Formed when agents like heat or pressure or both act on igneous or sedimentary rocks.
No fossils or strata
both
none
Q15: Chemical weathering occurs due to
Chemical Solution
Wet climates
Mineral composition of the rock and the density of joints and cracks
all
Q16: Physical weathering of rocks occurs due to
Repeated cycles of high and low temperatures
Repeated wetting and drying.
Biotic factors like plant roots
all
Q17: Sedimentary rock under heat and pressure becomes
igneous
sedimentary
granite
all
Q18: Metamorphic rock under process of weathering, erosion and subsequent lithification becomes
igneous
metamorphic
sedimentary
quartz
Q19: Continental drift theory
Alfred Wegener propounded it
It was based on matching coastlines, similarity in age of rocks, fossil evidence
similar plant and animal fossil found on both sides of the continents and glacial evidence in tropical lands.
all
Q20: Continental drift theory doesnt explain
how the gravitational forces could have affected the movement of continents
the driving force for the drift.
both
none
Q21: Convention current theory / sea floor spreading
A convention cell which is like a conveyor belt moves under the crust and is responsible for drifting of the continents.
The sea floor spreads due to the convention current and magma comes out this forms new ocean crust and expansion of ocean crust.
both
none
Q22: Which is true ?
Ocean crust near mid ocean ridge is younger
oceanic crust far away from mid ocean ridge is older
both
none
Q23: mid ocean ridges is caused by the
Divergent plate boundary
Convergent plate boundary
Transverse boundary
all
Q24:volcanic mountains like in Andes, rocky and atlas mountains are caused by
ocean ocean plate convergence
divergent plates
transverse plates
ocean continent plate convergence
Q25: island arcs and archipelagoes are caused by
ocean and ocean plate convergence
ocean continent plate convergence
both
none
