How are the inner planets believed to have been formed?
The explosions of supernovas
Which of the planets is the outermost of the four inner terrestrial planets?
Mars is the last of the inner planets. It is the fourth planet from the Sun and right before 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.
Why are the inner planets different to the outer planets?
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
Why do the planets roate?
They rotate do to the gravitational pull of the sun... The rotate themselves due to their inner core rotating which is also caused by gravity
Why inner planets are closer to the sun than outer planets?
The inner planets are closer to the sun than the outer planets because of the way the solar system formed. When the solar system was still a swirling disk of gas and dust, the inner planets formed closer to the center where it was hotter, while the outer planets formed in the colder regions farther away. This distribution of planets based on temperature led to the inner planets being closer to the sun than the outer planets.
How are the inner planets believed to have been formed?
The explosions of supernovas
How the rocky inner planets were formed?
By "accretion" of "planetesimals" from the "protoplanetary disk".

Are inner planets Rocky?
Th inner planets are rocky because as the Sun and planets formed the more volatile elements could not condense into droplets near to the hot Sun. Thus the inner planets are made form stuff with a high melting/boiling point and the outer planets (where it was cooler) are made from the gases.
What describes the four inner planets?
Rockey and hotter .1. These planets have gaseous atmospheres.2. The inner planets all have one moon each.3. These terrestrial planets have surfaces that are rocky hard.4. The inner planets were formed differently than the outer planets.Those are the choices.. Thankks for your help, if you decide to help.

What planets are formed from leftover formation of the sun at the center of the cloud?
All planets are formed form the remains of the solar nebular.
List inner planets and why they are inner planets?
The inner planets are Mercury, Venus, Earth, and Mars. They are "inner" because the are the first 4 planets from the Sun.
