How does the solar nebula theory help you understand the location of asteroids? How does the solar nebula theory explain the dramatic density difference between the Condensation is the building of larger particles one atom or molecule at a time, whereas accretion is the sticking together of larger particles.
The planets swept up gas, dust, and small particles. In planetary science, accretion is the process in which solids agglomerate to form larger and larger objects and eventually planets are produced. Accretion has to be effective and fast. A first process is the sticking of microscopic dust into larger grains and pebbles. A second process is the formation of an intermediate class of objects called planetesimals.
A third accretion process has to lead from planetesimals to planets. Accretion, the gradual clumping together of dust, rocks and meteorites into larger and larger bodies, eventually creates rocky planets, provided no larger gravitational bodies stop the process.
Accretion is the process in which material from the outer plate and trench during the periods of discontinuous subduction is removed and added to the outer continental margin or by other mechanisms such as imbricate thrusting or a combination of folding and thrusting Karig, ; Karig and Sherman, The process by which planets form as material orbiting some stars gathers together through collisions and gravitational or electrostatic attraction, eventually forming larger and larger bodies.

What is the difference between nebular hypothesis and solar nebula theory? What force pulls the matter in a nebula together? Step 5: Accretion. What is the process of accretion? What is the condensation sequence? What are the first four phases to condense out of the solar nebula? The ingredients of the solar nebula fell into 4 categories based on their condensation temperatures: metals, rocks, hydrogen compounds water, methane, ammonia , and light gasses hydrogen and helium.
Distance of a planet from the Sun determined the temperature and thus the materials which condensed first. What was the first stage in the formation of our solar system? Our solar system formed about 4. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula —a spinning, swirling disk of material.
