What advantage does space-based astronomy have over ground-based observations?
Closer proximity to celestial objects
Unobstructed view of the entire electromagnetic spectrum
Both a and b
None of the above

The following are the uses of Spectroscopy, which one is not?
Spectroscopy is used to determine the temperature of a star.
Spectroscopy is used for identifying gases and minerals, and determining star composition.
Spectroscopy is used as a method for observing meteor showers.
Both A and B are incorrect.
A specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky.
Lovell Telescope
Arecibo Telescope
Radio Telescope
Radio Waves
Why do sundials need to be adjusted throughout the year?
Due to changes in the Earth's magnetic field
Because the Sun's position in the sky changes with the seasons
To account for the rotation of the Moon
Because of fluctuations in atmospheric pressure
Why is Ionizing Radiation More Dangerous than Non-Ionizing Radiation?
Ionizing radiation can break chemical bonds and damage DNA, while non-ionizing radiation can only cause heating effects.
Ionizing radiation can cause nuclear reactions and transmute elements, while non-ionizing radiation can only excite electrons.
Ionizing radiation can produce ions and free radicals, while non-ionizing radiation can only alter the position of atoms.
All of the above.
What important role does space-based astronomy play in addressing global challenges like climate change?
Monitoring Earth's atmosphere and climate patterns.
Studying asteroids and comets that could pose a threat to Earth.
Developing technologies for sustainable space exploration.
All of the above.
Ionizing radiation consists of particles that have enough energy to completely removing an electron from its orbit, thus creating a more positively charged atom. Which of the following is not Ionizing Radiation?
GALACTIC COSMIC RADIATION
TRAPPED RADIATION
ULTRAVIOLET RADIATION
SOLAR ENERGETIC PARTICLES
What is a geostationary satellite?
A satellite that orbits the Moon
A satellite that remains fixed relative to a point on Earth's surface
A satellite that travels at very high speeds around Earth
A satellite used for interplanetary exploration
