Final answer:
Terrestrial planets and giant planets differ in composition, size, mass, and atmosphere.
Step-by-step explanation:
The giant planets and terrestrial planets differ in several ways:
- Composition: Giant planets have dense cores surrounded by layers of hydrogen and helium, while terrestrial planets consist mostly of rocks and metals.
- Size and Mass: Giant planets are much larger and have higher mass than terrestrial planets.
- Atmosphere: Giant planets have thick atmospheres composed mainly of hydrogen and helium, while terrestrial planets have much thinner atmospheres.
These differences in composition, size, mass, and atmosphere result in distinct physical and chemical properties for terrestrial and giant planets.
