Answer:
Option C:
The magma's cooling rate determines the size of crystals that are formed.
Explanation:
Once magma erupts from a volcano to the surface of the earth, it begins to cool because of the relatively cooler temperatures at the surface of the earth.
The magma usually cools down to form igneous rocks on the surface of the earth. The rate at which the magma cools down determines the size of the rock crystals that are formed.
If the magma cools slowly, there is enough time for crystal growth within the rock particles. This gives rise to larger rock crystals.
If the magma cools rapidly, there is little time for crystal growth. This leads to the presence of smaller rock crystals.
Answer:
Content validity
Explanation:
Content validity refers to the fact that a study actually measures all aspects of the construct.
For a study to be valid, <u>the measurement method must cover all relevant parts of the subject it is measuring</u>. If it doesn't do so, then the validity of the study is treatment because of content validity.
In this case, the construct we are studying (quality of a relationship) has three parts (belong, interdependence and intimacy). Since <u>the questionnaire doesn't include items tapping intimacy it is not covering all three parts of the construct</u> and therefore it is lacking content validity.
