Equals
Proportional
Decreases
Increases
60s - Q2
Each layer of the earth has its own distinct features, composition, properties and characteristics. Which among the layers of the earth has the highest temperature
The core which has decaying isotopes.
The mantle which is the mostly solid bulk layer of the earth.
The crust which is the most exposed to ultraviolet rays.
The lithosphere which is the solid part of the earth.
60s - Q3
Different elements with varying properties comprises the layers of the earth. Which layer of the earth has the highest amount of molten state iron?
The core which is the hot and dense inner most layer of the earth.
The crust which is the lightest and thinnest layer of the earth.
The mantle which is the most massive layer of the earth.
The lithosphere which is known as the solid outer most part of the earth.
60s - Q4
Why do you think Earth is considered as a thermal engine?
As a natural satellite the moon gives thermal energy to earth.
Too much pressure on the crust causes materials to be molted which gives large amount of heat.
Decay of isotopes contributes to the internal heat of the earth.
The energy coming from the sun gives tremendous heat on the surface.
60s - Q5
What do you think will happened to the amount of heat from the outermost layer of the earth down to its core?
As you move from the surface of the earth to the inner core the amount of heat becomes higher.
As you move from the surface of the earth to the inner core the amount of heat lower.
The amount of heat is indirectly proportional to the location of the earth.
The amount of heat in the surface of the earth is equal to its interior.
60s - Q6
Which of the following pertains to the process by whichgasses and dust of cloud were attracted by gravitational energy 4.6 billionyears ago?
Planetesimal
Accretion
Gravitational pull
Solidification
60s - Q7
Direct observation is not possible to know all the details about the interior of the earth due to its changing nature of internal composition and tremendous heat that come from its inner most layer. Which of the following will best describe the given sentence?
The statement is dependent on the inner or outer core.
The statement conveys incorrect information.
The statement conveys correct information.
The thought of the statement cannot be determined due to the nature of Earth.
60s - Q8
Which among the layers of the earth has the greatest pressure which contributes to the production of the tremendous internal heat?
Inner core has the greatest pressure among the layers of the earth.
Mantle contains most volume of the earth causing it to have high pressure.
Outer core has greater pressure than the inner core.
Crust has the greatest pressure due to movement of rocks.
60s - Q9
There are several sources that contribute to the internal heat of the earth. Which of the following is NOT a major process that contributed to Earth’s internal heat?
Primordial heat from the formation of the planet contributes to its internal heat.
As radioactive isotopes decay, it releases heat which contributes to the earth’s internal heat.
Heat released by colliding particles during the formation of the planet
When iron is crystallized heat is released causing the inner core to be the hottest layer.
60s - Q10
How did the Earth generate heat on its early stage of formation?
Due to the collision of huge amount of gas and dust particles.
Due gravitational pressure at the center of the planet.
Through absorption of energy from planetisimals.
Due to radioactive decay of some isotopes.
60s - Q11
What process exist as heat is transferred from one plate to another along plate boundaries?
Conduction
Radiation
Convection
Thermal transfer
60s - Q12
How do radioactive isotopes emit heat energy and contribute to Earth’s internal heat?
Due to spontaneous radioactive decay of isotopes.
Through gravitational pressure between particles.
Due to preservation of primordial heat from the earliest stage of the earth.
Through pressure freezing of the particles.
60s - Q13
How do naturally occurring isotopes play a vital role in the production of earth’s internal heat?
Due to chemical stability.
Due to its abundance and emission of heat when it decays.
Due to its high energy capacity.
Due to the heat it releases as it is subjected to low temperature.
60s - Q14
What happened to the pressure inside the Earth as you go deeper?
The pressure increases as you descend to the interior of the earth.
The pressure decreases as you descend to the interior of the earth.
The pressure is unstable and is affected by gravity.
The pressure is the same all throughout.
60s - Q15
Why does Earth’s internal heat builds up due to gravitational pressure?
Because the escape of heat from Earth’s surface is greater than the heat generated.
Heat cannot escape from the interior of the earth since it is a closed system.
The amount of heat that can be released on the surface is greater.
The amount of heat that can be generated on the earth’s interior is tremendous while lesser amount can escape on the surface.
