Question

How are marble and quartzite alike, and how are they different?

a. Marble and quartzite are alike in that they are both foliated, but they differ in that marble is composed of calcite whereas quartzite is composed of quartz.
b. Marble and quartzite are alike in that they are both composed of quartz, but they differ in that marble has slaty cleavage whereas quartzite is nonfoliated.
c. Marble and quartzite are alike in that they are both composed of quartz, but they differ in that marble is nonfoliated whereas quartzite is foliated.
d. Marble and quartzite are alike in that they are both nonfoliated, but they differ in that marble is composed of calcite whereas quartzite is composed of quartz.
e. Marble and quartzite are alike in that they are both nonfoliated, but they differ in that marble is composed entirely of micas whereas quartzite is composed of quartz.

Answer 1

Marble and quartzite are both types of metamorphic rocks, with marble composed of calcite and quartzite composed of quartz.

Although marble is nonfoliated and quartzite can be foliated or nonfoliated, both rocks are hard and commonly used in construction and sculpture.

Step-by-step explanation:

Marble and quartzite are both types of metamorphic rocks, but they have some key differences.

Marble is composed of calcite, while quartzite is composed of quartz.

Additionally, marble is nonfoliated, meaning it does not have a layered or banded structure, while quartzite can be foliated or nonfoliated.

Overall, the main similarity between marble and quartzite is that they are both hard rocks used in construction and sculpture.
