Explanation / Answer
1.)a.)S-waves do not pass through:
the asthenosphere
the outer core
the mantle
the lithosphere
ANSWER : the outer core
Explanation : S –wave can not pass through the liquid (as liquid has no rigidity ) . As outer core is in liquid state , therefore S-wave can not pass through the outer core .

ANSWER :
The most voluminous layer of the earth is the mantle .
QUESTION :
d.) Which layer of the earth is the thinnest?
the continental crust
the upper mantle
the ocean crust
the inner core
the outer core
ANSWER :
The thinnest layer of the earth is ocean-crust .( its thickness about 6 km to 8 km )
QUESTION :
e.) Which of the following features is the deepest?
the continental slope
the continental shelf
the abyssal plain
the continental rise
ANSWER : the abyssal plain
( An abyssal plain is an underwater plain on the deep ocean floor )
Explanation :
depth order from high to low
Abyssal plain> continental rise > continental slop > continental shelf
