Sentence usage of the word accretion?
This may have either inhibited sedimentation or promoted accretion in upper harbor areas.
What is accreation?
Creation through accretion - see www.accreation.org
How does an accretion disk form?
An creation disk may eventually form a
What is the process through which fragments in space are drawn together to form planets?
Accretion
What are the major steps of solar system formation in the correct order?
collapse, condensation, accretion
What is disturbed by an outside explosion for it to cause an accretion disk?
When a nebula is disturbed by an outside explosion, it may form an accretion disc.
Why the inner core is hot?
From incredible pressures, residual accretion heat, and nuclear reactions. == ==
How does accretion heat a planet?
During accretion, any object falling towards a planet will acquire a velocity because of the gravitational attraction from the planet. So, the object will have a kinetic energy due to its motion. During the the collision the kinetic energy is converted to heat energy, and the remain of this heat is actually heating the planet.
What is accretion Give me at least 4 examples of accretion as in accretion as the type of growth?
David Spade
What is antonym of avalanche?
vertical accretion vertical accretion
What is the difference between accretion and intusscuception?
the accretion and intussusception are similar
Does a accretion spin?
The accretion spin do to the unbalanced force of gravity.
The material that accretes onto a neutron star or black hole is expected to emit x-rays because?
Accretion disks generally are energetic because of gravitational compression of infalling matter, and frictional forces which heat the matter in the accretion disk. The frequency depends on the mass of the central body. Protostellar accretion disks emit in the infrared, the higher speed and friction associated with the more intense gravity of neutron stars and black holes cause them to radiate in the higher x-ray frequencies of the electromagnetic spectrum.
Will you explain about the outflow from the accretion disc?
Whats an accretion disc? Accretion disc is a disc of matter that falls on the black hole. It rotates around it rapidly, heating up and emitting radiation. Jets are due to twisting magnetic fields that if there are appropriate conditions cause particles from the disc to escape along its axis, forming jets.
What are the three principal sources of internal heat of terrestrial planets?
The three principal internal sources of heat for the terrestrial planets are;accretion,differentiation,radioactivity.The first two mainly occur during the planets formation. Accretion, as gas, dust and smaller bodies collide to form the planet, generating heat on impact and differentiation. Differentiation is the process where the most dense outer material falls to the centre of the planet heating the core through friction during accretion. The source of the thermal energy is the gravitational potential energy which the extended mass had before accretion. The planet holds this heat for billions of years.Radioactive material was present in the original accretion disk. The long lived radioactive elements decay for billions of years. (On Earth, these are potassium-40, uranium-238, uranium-235, and thorium-232.) This also contributes significantly to internal heating, as unstable radioactive nuclei split and release energy (fission).
Can you give me a sentence for accretion?
Accretion means gradually growing by layers. Seashells grow by accretion as the animals add new layers of calcium.
What is an accretion disc?
An accretion disc is a structure formed by matter falling into a gravitational source.
