Question

Rock A formed from small pieces of rock.
Rock B formed from liquid rock in a different place.
Rocks A and B formed at about the same time.
As they work on their study they need to answer the question: Are Rocks A and B the same or different types of rock?

The rocks are

Responses

a
the same type because they both formed from rock material.
the same type because they both formed from rock material.

b
the same type because they formed at the same time.
the same type because they formed at the same time.

c
different types because they formed in different places.
different types because they formed in different places.

d
different types because they formed in different ways.

Answer 1

The correct response is:

d different types because they formed in different ways.

Rock A formed from small pieces of rock (sedimentary), while Rock B formed from liquid rock (magma or lava, indicating an igneous origin). Despite both forming around the same time, their different formation processes indicate they are different types of rock.
