FLASHCARD QUESTION
Front
Explain why Jovian planets have a larger number of moons compared to terrestrial planets.
Back
Jovian planets have more mass and thus stronger gravitational pull to capture more moons.
Answer explanation
Jovian planets have more mass, resulting in a stronger gravitational pull. This allows them to capture and retain a larger number of moons compared to terrestrial planets, which are smaller and have weaker gravity.

FLASHCARD QUESTION
Front
How does the presence of a nebula contribute to the formation of stars?
Back
Nebulae contain the gas and dust that collapse under gravity to form stars.
Answer explanation
Nebulae are composed of gas and dust, which can collapse under their own gravity to form new stars. This process is essential for star formation, making the correct choice the one that highlights this role of nebulae.

FLASHCARD QUESTION
Front
Discuss the role of planetesimals in the formation of planets.
Back
Planetesimals collide and stick together to form larger bodies, eventually becoming planets.
Answer explanation
Planetesimals are crucial in planet formation as they collide and stick together, gradually building larger bodies that eventually become planets. This process is fundamental to the growth of planetary systems.
7.
FLASHCARD QUESTION
Front
Which of the following is NOT a characteristic of Jovian planets?
- They have thick atmospheres.
- They are located closer to the Sun than terrestrial planets.
- They have ring systems.
- They are larger than terrestrial planets.
Back
They are located closer to the Sun than terrestrial planets.
Answer explanation
Jovian planets are located farther from the Sun than terrestrial planets. They have thick atmospheres, ring systems, and are larger than terrestrial planets, making the second option the only incorrect characteristic.
