SOLAR SYSTEM

Detailed explanation-1: -The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma.

Detailed explanation-2: -Rocky planets are made mostly of rock and metal. They have a hot core surrounded by a layer of hot rock called the mantle. On the surface is a thin layer of solid rock called the crust.

Detailed explanation-3: -The four rocky planets are Mercury, Venus, Earth and Mars. They are the closest four planets to the Sun. They are made of rocks and metals. They have a solid surface and a core which is mainly made of iron.

Detailed explanation-4: -Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth’s moon.

Detailed explanation-5: -Unlike the terrestrial planets that make up our inner solar system-Mercury, Venus, Earth, and Mars-the Jovian planets do not have solid surfaces. Instead, they are composed primarily of hydrogen and helium, with traces of methane, ammonia, water, and other gases in their atmospheres.
