Question

1. geologists in egypt and ethiopia are comparing rock samples from rocks found in the two countries. they are sharing information about the rocks to figure out whether they are the same or ent types of rock. the information is as follows:

• 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.

are rocks a and b the same or different types of rock?
the rocks are
a different types because they formed in different ways.
b different types because they formed in different places.
c the same type because they both formed from rock material.
d the same type because they formed at the same time.

Explanation:

Rocks are classified based on their formation processes. Rock A formed from small pieces of rock (a characteristic of sedimentary rocks), while Rock B formed from liquid rock (a characteristic of igneous rocks). Different formation processes mean different rock types. The place of formation (as long as the process is the same, rocks can be same - type even if formed in different places) and time of formation (time alone doesn't determine rock type) are not the key factors here. Just forming from rock material (all rocks are made of rock - material in a sense) is too vague.

Answer:

A. different types because they formed in different ways.
