What three types of materials thought to make up the inner planets?
There isn't a specific substance that planets are made of. Most planets are made of solids and/or gases. As far as we know, there may be a planet somewhere out there that's made of liquids.Gases, rocks, and ices
What caused dust and condensing material to accrete into planetesimals?
Gravity probably had some effect, but "van der Waals" forces are thought to have been the main cause, in the early stages. These are electrical forces between atoms, molecules, etc.
Do all inner planets have a thin atmospheric shell?
Each of the four inner planets has an atmosphere, except Mercury. Mercury is too small and close to the sun for its gravity to sustain a proper atmosphere, although a tenius and unstable exosphere it thought to exist.
Do gas giant planets have solid cores?
The four gas giants of our solar system are thought to have small, dense cores of metal and rock, but mainly consists of liquid hydrogen and helium at immense pressure.
What are the two main gases in the Sun?
Hydrogen and Helium . When all the hydrogen is used up , it is thought that the helium will convert into carbon, and the Sun will become a Red Giant. At this late stage it will swallow up all the inner rocky planets including Earth; but that is millions of years into the future.
What is the term used to describe an object that is much smaller than a planet and which condensed from a cloud of interstellar gas and dust?
Scientists believe that the solar system is about 4.5 billion years old, and that it began as a cloud of interstellar gas and dust. This cloud of matter then condensed and fragmented into tiny ( compared to planets ) objects called planetesimals. These planetesimals then came together due to gravity to from the planets we know now. It is thought that many asteroids are planetesimals that never came together.
What is Jupiter thought to be like beneath its cloud?
There is thought to be a molecular hydrogen layer, and a liquid metallic hydrogen layer. At high pressures, hydrogen forms a liquid metal which is a very good electrical conductor. We think this because combined with rapid rotation, a dynamo is formed, producing Jupiter's intense magnetic field. There is also thought to be a rocky core that was formed by planetesimals, which basically supplied the initial gravity to hold the gases and create a gigantic gaseous planet.
The natural force thought to hold planets in orbit is called the what force?
GRAVITY!! i could be wrong...
How are tides planets and black holes related?
There is a force that unites the tides, planets and black holes. Tides are generally thought of as the rise and fall of the level of the oceans due to the gravitational effects of the moon and the sun. Planets have gravity proportional to their masses, and black holes are points of massive gravity. Gravity or its effects unite the three things listed.

why was gravity made or like thought of?
it holds the planets that orbit around the sun and what keeps the moon in orbit around the Earth

Gravity probably had some effect, but "van der Waals" forces are thought to have been the main cause, in the early stages. These are electrical forces between atoms, molecules, etc.
How was your planet thought to have been formed?
Earth, like all planets, was formed by clumps of matter joining together due to gravity.
The outer planets are made up of which gases?
The composition of Jupiter and Saturn are mostly helium and hydrogen with trace amounts of hydrogen compounds such as methane, ammonia and water. Neptune and Uranus consist mostly of methane, ammonia and water, with small amounts of elemental hydrogen and helium. Jupiter is thought to have no definite core, while Saturn is thought to have a dense core of iron, nickel, silicon and oxygen compounds. Neptune is thought to have a core of molten rock (as well as water, hydrogen, helium, ammonia, and methane). Uranus is thought to have a core similar to Saturn's.
Hydrogen ions H plus can be thought of as?
Hydrogen ions (H+) can be thought of as protons.
A hydrogen atom that does not contain a neutron hydrogen ions can can be thought of as?
Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
