How would i describe the protoplanet hypothesis? | …

As the protoplanets grew, another process became important. The strong gravitational fields produced many high-speed collisions between planetesimals and protoplanets. These collisions led to , as small objects broke into still smaller chunks, which were then swept up by the protoplanets. Not only did the rich get richer, but the poor were mostly driven to destruction! Some of these fragments produced the intense meteoritic bombardment we know occurred during the early evolution of the planets and moons, as we have seen repeatedly in the last few chapters. A relatively small number of 10—100-km fragments escaped capture by a planet or a moon to become the asteroids and comets.

Solar Nebular Hypothesis: Definition & Explanation - …

These protoplanetary disks span about 0.14 light years and are probably similarto the Solar Nebula.

The second is that encounters between stars are extremelyrare, so rare as to be improbable in the lifetime of the Universe (15billion years).Nebular Hypothesis:A second theory is called the nebular hypothesis.

Nebular Hypothesis - University of Winnipeg

Venus has been referred to as Earths sister planet. The reason forthis is its size, density, and distance from the sun resembles that ofEarth . Therefore, it was once thought thatthe environment on Venus would be similar to that of Earth (especiallysince they formed from about the same position in the solar nebula). SinceVenus is closer to the Sun than the Earth, three things led to the formationof a dense atmosphere on Venus:

The inclusionsare aluminum-rich minerals that formed first in the solar nebula.

A Medley of Potpourri: Nebular hypothesis

Itincorporates many of the components of the nebular hypothesis, but addssome new aspects from modern knowledge of fluids and states of matter.Meanwhile in the inner Solar System:Note that as the planet's began to form they grew in mass by accretingplanetesimals.

How earth was formed in the nebular hypothesis

The early proto-planets areable to sweep the early Solar System clean of large bodies.Notice also that the lighter compounds are vaporized in the inner SolarSystem.

The increase in rotation speed, in turn, must have caused the nebula's to change as it collapsed. In Chapter 11 we saw how a spinning body tends to develop a bulge around its middle. The rapidly spinning nebula behaved in exactly this way. As shown in Figure 15.1, the fragment eventually flattened into a pancake-shaped primitive solar system. If we now suppose that planets formed out of this spinning material, we can already begin to understand the origin of some of the large-scale architecture observed in our planetary system today, such as the circularity of the planets' orbits and the fact that they move in nearly the same plane.

As the planetesimals shrink in average size, collisions withproto-planets lead to fragmentation.

What Is the Nebular Theory? | Education - Seattle PI

This difference is best explained by the theory that differing proportions of tungsten-182 each accumulated after the giant moon-forming impact, the researchers say. "Our results provide independent evidence for the late-veneer hypothesis," Kruijer said. The research in these two studies was also .

This might later evolve in the same way as the original nebula, thus producing satellites.

The orbit of asteroids is variable. If one comes too close to a planet,the force of that planets gravity could cause the asteroid to fall andhit the planet's surface. As an asteroid falls toward the surface of aplanet, it heats up by friction with the atmosphere and begins to glow;this is termed a meteor. Most meteors burn before hitting the surface buta few actually reach it. The impact of meteors can cause craters on thesurface to form which, as we learned, is what gave the terrestrial planetsdifferent terrains and shapes.

These rocks are called and provide valuable information about the primordial solar nebula.
