Answer:
1- Option (D)
2- FALSE
Explanation:
The seafloor spreading takes place because of the divergent plate motion. Alfred Wegener observed this motion of the seafloor and the continents but was not able to explain the main mechanism behind this until the new theory came into the picture. The divergent motion of seafloor and the motion of the continents were explained by the universally accepted theory known as the Plate tectonic theory. This theory was able to explain the mechanism behind this plate motion.
The study of the seafloor spreading provided some pieces of evidence that supported the continental drift theory. They gave a basic idea about how the oceanic plate gets subducted (consumed) at the convergent plate motion that undergoes partial melting at greater depth. As a result of which the magma rises up to the surface on the overriding plates.
The crust represents the outermost layer of the earth. They are of 2 types, namely the oceanic and the continental crust. These crusts when slide past one another in a transform plate boundary, it is neither created nor destroyed. It remains conserved.
Thus, the correct answers are given above and the second statement is false.

Answer:
2.5 km = 250000 cm
500 ft = 15240 cm
Explanation:
part a
given data
length = 2.5 km
to find out
Convert into cm
solution
we know that 1 m = 100 cm ...............1
and also we know 1 km = 1000 m .................2
sop as that we can say from equation 1 and 2
1 km = 100000 cm
so for 2.5 km = 2.5 × 100000 cm
2.5 km = 250000 cm
and
part b
given data
length = 500 ft
to find out
Convert ft into cm
solution
we know here that
1 ft = 12 inches ..................1
and also we know 1 inch = 2.54 cm ...................2
so we can say
500 ft = 12 × 500 inches
500 ft = 6000 inches
and 500 ft = 6000 × 2.54 cm
500 ft = 15240 cm
