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.
What are strengths of the nebular theory?
The nebular theory effectively explains the formation of solar systems through the collapse of a rotating cloud of gas and dust, leading to the creation of stars and planets. It accounts for the observed disk-shaped structures of protoplanetary disks and the angular momentum distribution in solar systems. Additionally, the theory is supported by various astronomical observations, including the discovery of protoplanetary disks around young stars and the chemical composition of celestial bodies, which align with predictions made by the theory. Its flexibility allows for adaptations in understanding different types of celestial formations across the universe.
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 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.
What is a proplyd?
it is exactly protoplanetary disk.
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.
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.
When did compact disks first become available?
Before 1975. Check with PHILLIPS the originator of CDs
How will you know when photosynthesis is occurring in your leaf disks?
Photosynthesis in leaf disks can be detected by observing the buoyancy of the disks as they float. When photosynthesis occurs, oxygen is produced as a byproduct, causing the disks to become buoyant and rise to the surface of the water. Typically, this process can be observed through a change in the position of the disks within a given time frame, indicating that photosynthesis is actively taking place. Additionally, an increase in the number of floating disks over time serves as a clear indicator of photosynthetic activity.
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.
