Earth definitely does. Possibly Venus and Mars have (or have had) a rock cycle of some sort, too. However, Venus and Mars lack liquid water and tectonic plates, which are important in Earth's rock cycle.
On Earth, the rock types involved in the cycle are igneous (of volcanic origin), sedimentary and metamorphic.
The terrestrial planets are primarily composed of rock and the jovian planets are mostly gas (primarily Hydrogen). Rock has a higher density than Hydrogen, giving the terrestrial planets a higher density.
The Rocky planets are Mercury, Venus, Earth and Mars. They are all the planets with a solid surface made of rock.
planets of course, or asteroids. both are rock
This cycle is called Metamorphism.
Because the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
there are 9 planets
They have solid surfaces composed of rock.
there are gas planets and rock planets
the endpoint of a rock cycle is the metamorphic rock
No, the rock cycle does not have to start from the sedimentary rock
Terrestrial planets.
The rock cycle and water cycle both are natural.
It is called the Rock Cycle.
The first 4 planets, Mercury, Venus, Earth, and Mars, are called rock planets, and the last 4, Jupiter, Saturn, Uranus, and Neptune, are the gas planets. The main differences between these two groups are that the rock planets are made of rock, the gas planets are made of gas, the rock planets are typically smaller than the gas planets, and the gas planets have rings.
it is a true cycle because it the rock cycle
Mercury. It has the longest cycle of ALL the planets, not just terrestrial.
A rock cycle is a model that shows the cycle of rocks from the formation to the breakdown and to the reformation. He used a rock cycle for his science project.
