Question 5 medium
Which of the following best describes the difference between weather and climate?
Show answer & explanation
Correct answer: C — Weather describes short-term atmospheric conditions, while climate represents long-term patterns over decades.
Weather refers to short-term variations in the atmosphere (hours or days), whereas climate is the statistical average of weather patterns over long periods (typically 30 years or more).
-
Question 6 medium
A scientist who specializes in studying weather patterns, climate dynamics, and the Earth's atmosphere is a(n)
Show answer & explanation
Correct answer: A — meteorologist.
A meteorologist studies atmospheric conditions, weather forecasting, and climate processes, distinct from scientists who focus on oceans, fossils, or earthquakes.

Question 8 hard
Extreme tides known as 'spring tides' occur under which alignment of celestial bodies?
Show answer & explanation
Correct answer: C — When the Earth, Sun, and Moon align in a straight line during new and full moon phases.
Spring tides occur when the gravitational pulls of both the Sun and Moon combine during full and new moon phases when they align with Earth.
-
Question 9 hard
Which planet in our solar system has the highest surface temperature primarily due to a dense, greenhouse gas-rich atmosphere?
Show answer & explanation
Correct answer: B — Venus
Although Mercury is closer to the Sun, Venus has the hottest surface temperatures (around 465°C) because its thick atmosphere traps heat through a runaway greenhouse effect.
