What observation made of other stars seems to suggest the solar nebula hypothesis is correct?
The presence of protoplanetary disks around other stars, known as proplyds, supports the solar nebula hypothesis. These disks resemble the early solar system's disk of gas and dust that eventually formed the planets. Additionally, the discovery of exoplanets in various stages of formation further reinforces the solar nebula hypothesis.
What is the force that caused the formation of the plants in our solar system?
Plants in our solar system, including those on Earth, formed due to the force of gravity that led to the condensation of dust and gas in the early solar system. This process eventually allowed for the formation of protoplanetary disks, which served as the birthplace of plants through processes such as accretion and differentiation.
How did Jupiter become the biggest planet?
Jupiter is the biggest simply because it got the most stuff out of the "protoplanetary" disk from which the planets formed.
What planets are formed from dust and compacted gas?
Planets such as Earth, Venus, and Mars are formed from dust and compacted gas in the early stages of their formation within protoplanetary disks around young stars. These dust particles and gas eventually clump together through collisions and gravitational forces to form planetesimals, which further grow into planets over millions of years.
What is a proplyd?
it is exactly protoplanetary disk.
What causes clouds to form individual planets over time?
Clouds of gas and dust in space can collapse due to gravity, forming protoplanetary disks. These disks then clump together to form individual planets over millions of years through a process called accretion. As the planet grows larger, it clears out its orbital path and becomes a distinct entity in its own right.
Why are there discs of cartilage in the vertebral column?
Cartilage disks in the vertebral column provide flexibility and shock absorbing qualities to the spine. These disks become less elastic with age.
When did compact disks first become available?
Before 1975. Check with PHILLIPS the originator of CDs
What forms when nebulae particles join?
When particles in a nebula join together, they can form larger structures such as stars and planets through a process called accretion. As these particles clump together due to gravitational attraction, they increase in mass and density, eventually leading to nuclear fusion in the core of a star. Surrounding material may also coalesce to form protoplanetary disks, from which planets, moons, and other celestial bodies can develop. This process is fundamental to the formation of solar systems.
Why did the leaf disks in the dark not float?
The leaf disks in the dark did not float because photosynthesis, which produces oxygen and causes them to become buoyant, was not occurring without light. In the absence of light, the leaf disks could not convert carbon dioxide and water into glucose and oxygen, leading to no oxygen bubbles being trapped within the disks. As a result, the disks remained denser than the surrounding water and sank rather than floating.
How will the sun evolve after the main star?
After the Sun leaves the main sequence (By running out of fuseable hydrogen) it will become an asymptotic red giant. After that, when it runs of of all fuel, stellar winds will blow away the Sun's envelope into a protoplanetary nebula (and eventually a planetary nebula) with a white dwarf in the middle, which will slowly cool to background temperature over ten quadrillion years.
How the rocky inner planets were formed?
By "accretion" of "planetesimals" from the "protoplanetary disk".
