TRUE
FALSE
How do asteroids orbit the Sun?
Through magnetic fields interaction
Due to the gravitational pull between the Sun and the asteroid
Because they are pushed by solar winds
By following a predetermined path
How do asteroids pose a potential threat to Earth?
Due to the possibility of impact, which can result in significant damage, mass extinction events, and disruption of ecosystems.
Asteroids are easily deflected by Earth's atmosphere
Asteroids are too small to cause any damage
Asteroids are harmless space rocks
What is the role of Jupiter in protecting Earth from asteroid impacts?
Jupiter's rings act as a shield against asteroid impacts on Earth.
Jupiter's gravitational pull deflects or captures asteroids that could otherwise collide with Earth.
Jupiter's magnetic field repels asteroids away from Earth.
Jupiter's moons absorb asteroid impacts before they reach Earth.
What are Near-Earth Objects (NEOs) and why are they important to study?
NEOs are fictional objects created for entertainment purposes.
NEOs are distant stars that have no impact on Earth.
NEOs are underground minerals that are not relevant to scientific study.
NEOs are comets and asteroids that have orbits bringing them close to Earth, and studying them is crucial due to their potential impact threat.
How do scientists track and study asteroids that come close to Earth?
Telescopes, radar systems, and spacecraft are used to observe asteroids' characteristics and movements.
Using a crystal ball to predict their movements
Using weather balloons equipped with sensors
Sending messages to the asteroids
