Detailed explanation-1: -Terrestrial planets are Earth-like planets made up of rocks or metals with a hard surface. Terrestrial planets also have a molten heavy-metal core, few moons and topological features such as valleys, volcanoes and craters.

Detailed explanation-2: -Terrestrial planets (Earth sized and smaller) are rocky worlds, composed of rock, silicate, water and/or carbon.

Detailed explanation-3: -The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.

Detailed explanation-4: -The following are reasons being terrestrial planets rocky Terrestrial planets are formed close to Sun where it was too warm for gases to condense to solid particles; only rocky particles remain. The solar wind was most intense near the sun, so it blew off lighter particles materials from terrestrial planets.

Detailed explanation-5: -Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water.
