Identify the region where temperatures are ideal for rocks and metals to exist in solid form.

The region that contains terrestrial planets is ideal for rocks and metals to exist in solid form because it is close to the sun and has a warm temperature; this warm temperature helps rocks and metals condense and exist in solid form.

To identify the region where temperatures are ideal for rocks and metals to exist in solid form, you must gain an understanding of what terrestrial and gaseous planets are and how they differ from one another.

First, within the Solar System, there are Earth-like planets and Jupiter-like ones. Terrestrial bodies are called Earth-like planets because they have attributes that match those of planet Earth; they have a rocky surface as well as a molten core. There are four terrestrial planets: Mercury, Venus, Earth, and Mars. Gaseous bodies are termed Jupiter-like planets because they have characteristics that mirror those of the planet Jupiter; they are giant balls of gas and are comprised of a great deal of helium and hydrogen. There are four gaseous planets: Jupiter, Saturn, Uranus, and Neptune.

Second, terrestrial and gaseous planets have noticeable differences in regard to temperature. Since terrestrial planets are close to the sun, they are warmer than gaseous ones; note that it is quite easy for rocks and metals to condense in a terrestrial planet's warm environment. Due to the fact that gaseous planets are far away from the sun and are colder than their terrestrial counterparts, it is harder for rocks and metals to condense within them; in fact, gaseous planets are typically associated with ice condensation.
