The other terrestrial planets are made of the same materials as Earth and formed in the same way, which means they have hot interiors. While Venus and Mars probably lack plate tectonics, they appear to have volcanoes associated with hot spots, which account for some volcanoes on Earth as well.

What separates the terrestrial and jovian planets?

In our solar system, the asteroid belt lies between the two types of planets. Whether this is due to some overarching influence or merely coincidental cannot be determined at the present time. Mercury, Venus, Earth, and Mars are small rocky, terrestrial planets. Jupiter, Saturn, Uranus, and Neptune are larger, predominantly gaseous planets. Beyond Neptune are many small plutoids and other icy bodies, some of which approach the size of the terrestrial planets. Their gaseous composition, however, means that they would lose much of their mass if they were closer to the Sun.


What is the primary difference in composition between the Sun and the terrestrial planets is?

Dependant on how the debris from supernovae is moving, the proportions of certain materials present, and the initial conditions of solar systems forming different combinations of terrestrial and Jovian planets are formed. Terrestrial planets are comprised of heavier particles (ie. of higher relative atomic mass) meaning they have stronger gravity which leads to higher density planets than the gaseous Jovian planets. A Jovian planet can be thought of as a failed star - it has all the elements needed to fuel nuclear fusion, but not enough gravity to attain the nuclear activation energy required. So the Sun started as a large cloud mostly comprising of gases, and terrestrial planets were formed from clouds mostly consisting of heavy solids.

Do any of the planets have nickel in them?

Mars, Earth and Venus very probably have substantial deposits of nickel, and nickel is common among meteorites. So it is also likely that iron and nickel will be fairly common in the asteroid belt.


What substances existed as solid flakes within the inner 0.3 of the solar system before planets?

Dust grains, ice particles, and rocky fragments were present as solid flakes in the inner 0.3 AU of the solar system before planets formed. These materials gradually accreted and collided to form planetesimals, which later grew into protoplanets and finally, the inner terrestrial planets we see today.


Does Mars have volcanoes active now?

There is currently no evidence to suggest that Mars has active volcanoes. However, many of its volcanoes are considered extinct, with evidence of past activity visible on the surface.
