Answer: C) extremely rapid cooling
Explanation:
When magma goes through extremely rapid cooling and especially if it did not dissolve enough water into it, it could freeze to glass or the mineral crystals that will be formed will be so small, they will look like glass.
This is because the reactions that occur to create minerals are affected directly by temperature such that if the magma cools down extremely slowly, it will form very large crystals but extremely fast would result in small crystals.
Answer:
A- Metacognition
Explanation:
The term <em>metacognition</em> refers to processes used to monitor and regulate one's thinking, understanding, and performance. It includes a critical awareness of one's thinking and learning and oneself as a thinker and learner. For example, you may be aware that you have trouble remembering people's names and remind yourself that you should try harder to remember the name of the person you met. Metacognitive strategies are often used to help students understand the way they learn and enhance their performance.
For a marketing research study to have validity, it must actually measure what it sets out to measure.
Explanation:
When it comes to research, we need to make sure that the measures we are using are reliable and valid.
Reliability refers to consistency across time, items, and researchers. Validity refers to what degree the results of the research reflect what they are intended to reflect (if the research actually measures what it has set out to measure). There are three main types of validity:
- face validity - the extent to which the research actually measures what it's supposed to measure;
- content validity - the extent to which a measure represents all aspects of the researched phenomenon;
- criterion validity - whether the results of the research correlate with other variables they are expected to be correlated with and not correlated with variables they are not expected to be correlated with.
