fill in the blank question
blank planets are closest to the sun. they are made of solid, blank materials. blank planets are farthest from the sun. they are made of blank and gases.

Explanation:

To solve this, we recall planetary classification. Terrestrial (inner) planets are closest to the Sun, made of solid, rocky materials. Jovian (gas giant/outer) planets are farthest, made of liquids (like liquid hydrogen/helium) and gases.

Answer:

First blank: Terrestrial
Second blank: rocky
Third blank: Jovian (or Gas Giant)
Fourth blank: liquids (or ice, depending on context, but "liquids" aligns with gas giant composition of liquid metallic hydrogen etc.)
