Answer:
Meteorology
Meteorology focuses on atmospheric processes, weather patterns, and climate. It uses data from satellites, radars, and models. Unlike geology, it studies the sky and atmosphere.
13
The importance of the scientific method lies in
Answer:
Standardizing research
The scientific method provides a universal process for inquiry, ensuring objectivity. It allows scientists worldwide to replicate and verify results. This standardization builds trust in findings.
14
Which of the following is NOT a scientific skill?
Answer:
Arguing
Science emphasizes constructive skills like observing, predicting, and measuring. Arguing is not a scientific method and does not generate evidence. Skills must contribute to investigation and accuracy.
15
Scientists value observations that are
Answer:
Measurable
Reliable observations are quantitative or measurable, reducing subjectivity. This ensures consistency and reproducibility. Measurable data forms the backbone of credible science.
16
To view tiny organisms, scientists commonly use a
Answer:
Microscope
Microscopes magnify small organisms invisible to the naked eye. They reveal cell structures and microbes. Telescopes and binoculars focus on distant objects, not microscopic ones.
17
The natural world refers to
Answer:
All living and non-living things not made by humans

18
Which of the following is NOT a pure science?
Answer:
Engineering
Pure sciences aim to expand knowledge, while applied sciences like engineering focus on practical use. Physics, chemistry, and astronomy are fundamental sciences. Engineering applies scientific knowledge.
19
Every scientific investigation begins with
Answer:
A problem or question
Inquiry starts by identifying a problem or asking a question about natural phenomena. This directs observations and experiments. Without a clear question, scientific research lacks focus.
20
Drawing a conclusion from evidence is known as
Answer:
