Multiple-Choice Questions
Aerial view of land and water. A yellow circle with the number "1" is on land, another yellow circle labeled "2" is on the water.
10. A team of engineers wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in South Korea (1) and in the Yellow Sea (2). Where will the team find hard, solid rock?
Responses

a
neither under 1 nor 2, because there is water under both places
neither under 1 nor 2, because there is water under both places

b
neither under 1 nor 2, because there is sand and gravel under both places
neither under 1 nor 2, because there is sand and gravel under both places

c
under 1 and 2, because Earth’s entire outer layer is made of hard, solid rock
under 1 and 2, because Earth’s entire outer layer is made of hard, solid rock

d
only under 1, because Earth’s outer layer is made of hard, solid rock under continents but not under the ocean
only under 1, because Earth’s outer layer is made of hard, solid rock under continents but not under the ocean

Answer 1

The correct response to the question about where the team of engineers will find hard, solid rock is:

d. only under 1, because Earth’s outer layer is made of hard, solid rock under continents but not under the ocean.

This is because the continental crust, which is typically composed of hard, solid rock, is found under land areas (like South Korea), while the oceanic crust, which is often less consolidated and can be composed of softer materials like sediments, is found under bodies of water (like the Yellow Sea).
