Question

eighth grade
planets are large, roughly spherical objects that orbit stars. their orbits tend to be nearly circular or oval - shaped. in the solar system, planets orbit the sun.
there are two types of planets in the solar system: rocky planets and giant planets. rocky planets are mostly made of rock and metal. they have a diameter between 4,800 and 12,800 kilometers. giant planets are mostly made of gas and ice. they have a diameter between 49,000 and 143,000 kilometers.
both types of planets can have moons and atmospheres. giant planets can have rings. rocky planets can have craters and volcanoes.
select the true statements about planets in the solar system.

• only rocky planets have rings.
• some giant planets have a diameter of less than 5,000 kilometers.
• all planets in the solar system orbit the sun.
• planets orbits tend to be nearly circular or oval - shaped.

Explanation:

1. For "Only rocky planets have rings": The text says "Giant planets can have rings", so this is false.
2. For "Some giant planets have a diameter of less than 5,000 kilometers": Giant planets have diameters between 49,000 and 143,000 km, so this is false.
3. For "All planets in the solar system orbit the Sun": The text states "In the solar system, planets orbit the Sun", so this is true.
4. For "Planets' orbits tend to be nearly circular or oval - shaped": The text says "Their orbits tend to be nearly circular or oval - shaped", so this is true.

So the true statements are "All planets in the solar system orbit the Sun" and "Planets' orbits tend to be nearly circular or oval - shaped".

Answer:

• All planets in the solar system orbit the Sun.
• Planets' orbits tend to be nearly circular or oval - shaped.
