1. What is the primary scientific purpose of the International Space Station (ISS)?

  1. To mine valuable minerals from nearby asteroids
  2. To serve as an inhabited orbital research laboratory in microgravity conditions
  3. To launch nuclear weapons into distant solar systems
  4. To provide luxury commercial tourism hotels in orbit
Show answer

Answer: B

The ISS provides a continuous microgravity environment for scientific experiments in biology, physics, medicine, and astronomy.

2. Which sensor spectrum is commonly used in remote sensing satellites to detect temperature variations and forest fires?

  1. Ultraviolet sensors
  2. Infrared sensors
  3. X-ray detectors
  4. Gamma radiation monitors
Show answer

Answer: B

Infrared sensors detect thermal radiation emitted by hot surfaces, making them ideal for spotting heat anomalies and forest fires.

3. Which astronomer proposed the Geocentric Model stating that Earth is fixed at the center of the Universe?

  1. Nicolaus Copernicus
  2. Claudius Ptolemy
  3. Johannes Kepler
  4. Galileo Galilei
Show answer

Answer: B

Claudius Ptolemy formulated the Geocentric Model where Earth was considered the static center of the Universe.

4. Who was the first scientist to use an optical telescope to observe astronomical bodies in 1609?

  1. Isaac Newton
  2. Galileo Galilei
  3. Yuri Gagarin
  4. Edwin Hubble
Show answer

Answer: B

Galileo Galilei was the pioneer who built and pointed an optical refracting telescope toward the night sky in 1609.

5. Which astronomical instrument collects radio frequency signals emitted by stars, nebulae, and distant galaxies?

  1. Refracting optical telescope
  2. Radio telescope
  3. Infrared microscope
  4. Seismograph
Show answer

Answer: B

Radio telescopes use large parabolic dish antennas to detect radio waves emitted by astronomical objects.

6. Which Malaysian satellite was launched into space for Earth observation and remote sensing research?

  1. MEASAT-1
  2. RazakSAT
  3. ASTRO-1
  4. TungkuSAT
Show answer

Answer: B

RazakSAT is a Malaysian high-resolution Earth observation satellite launched into a Near-Equatorial Orbit.

7. Which historical space mission successfully landed the first humans on the Moon in July 1969?

  1. Sputnik 1
  2. Apollo 11
  3. Voyager 1
  4. Vostok 1
Show answer

Answer: B

NASA's Apollo 11 mission landed Neil Armstrong and Buzz Aldrin on the lunar surface on July 20, 1969.

8. How did Johannes Kepler modify Nicolaus Copernicus's Heliocentric Model?

  1. He placed Earth back at the center of the universe.
  2. He showed that planets revolve around the Sun in elliptical orbits rather than circular orbits.
  3. He proved that the Sun orbits around Jupiter.
  4. He proposed that planets travel in straight lines through space.
Show answer

Answer: B

Kepler refined the heliocentric model by discovering that planetary orbits around the Sun are elliptical, not perfect circles.

9. Which model of the Solar System was published by Nicolaus Copernicus in 1543?

  1. Geocentric Model (Earth at the center)
  2. Heliocentric Model (Sun at the center)
  3. Galactic Core Model (Black hole at the center)
  4. Tychonic System Model
Show answer

Answer: B

Copernicus proposed the Heliocentric Model, placing the Sun at the center of planetary orbits.

10. Which of the following is an application of remote sensing in AGRICULTURE?

  1. Locating deep crust fault lines for earthquake prediction
  2. Detecting crop health, disease outbreaks, and soil moisture levels
  3. Tracking military troop movements along borders
  4. Measuring iceberg melting volumes in the Antarctic
Show answer

Answer: B

Multispectral sensors on satellites measure light reflection from vegetation to assess chlorophyll concentration and crop health.
