What are planetesimals and protoplanets and how are related to one another?
Planetesimals are small solid objects that form in the protoplanetary disk around a young star, while protoplanets are larger bodies that develop from the accumulation and collision of planetesimals. Planetesimals are the building blocks that come together to form protoplanets, and eventually, planets. So, planetesimals are like the "seeds" that grow into protoplanets.
Which process can be explained by the kinetic-molecular theory?
The process of gas molecules in a container moving in straight lines, colliding with each other and the walls of the container can be explained by the kinetic-molecular theory. This theory describes how the behavior of gas molecules is influenced by their motion and energy.
What is the key ingredient in the modern condensation theory of the solar system's origin that was missing or unknown in the nebula theory?
The key ingredient in the modern condensation theory that was missing in the nebula theory is the understanding of the role of turbulence. Condensation theory incorporates the effects of turbulence in the early solar system, showing how it can facilitate the collapse of material into the Sun and the formation of planetesimals. This provides a more detailed and realistic explanation for the formation of the solar system compared to the original nebula theory.
What are 3 conditions required for a successful collision theory?
Three conditions required for a successful collision theory are: sufficient energy to overcome the activation energy barrier, proper orientation of colliding molecules, and effective collision frequency between reacting molecules.
What are examples of collide?
Two cars colliding in a traffic accident. A basketball player colliding with an opponent while going for a rebound. Two storm systems colliding and creating severe weather conditions. A cyclist colliding with a pedestrian on a crowded sidewalk.
What are the names of the way the moon formed?
The fission theory, the capture theory, the condensation theory, the colliding planetesimals theory and the ejected ring theory.
Who was the scientist who discovered the planetesimals theory?
Viktor Safronov
What are the names of the theorys of the way the moon formed?
Some theories on how the moon formed include the Giant Impact Hypothesis, the Fission Hypothesis, and the Capture Hypothesis. These theories suggest that the moon was either formed from debris created by a collision with a Mars-sized body, split off from Earth due to rapid rotational spinning, or captured by Earth's gravity from elsewhere in space.
What causes planetesimals to stay together forming planets when they collide?
Planetesimals stick together due to gravitational attraction and potentially other forces, such as electrostatic forces or chemical bonds. When two planetesimals collide with enough energy, they can merge and form larger bodies, eventually leading to the formation of planets. The exact mechanisms depend on factors like the size, composition, and relative velocities of the colliding bodies.
How many stages are in The condensation theory?
There are six different stages in the condensation theory. These include the formation of a nebula cloud, the formation of a sun, the formation of planetesimals, the expulsion of gases from the forming sun, the growth of the planetesimals, and the formation of larger planets from planetesimals.
What are plantesimals?
Planetesimals are small, solid objects that formed in the early solar system out of dust and gas. They eventually collided and grew larger to become protoplanets, which further developed into the planets we know today. Planetesimals played a crucial role in the formation of our solar system.
What is part of the theory of plate tectonics?
The theory is that the tectonic plates have faults and are colliding, moving away, or going by each other. ~Toria, 12
Are stars smaller than planetesimals?
No. Stars are many times larger than planetesimals.
How is a mountain formed by colliding continental plates?
In theory, tectonic plates. http://www.ucmp.berkeley.edu/geology/tectonics.html
Planetesimals made of ice are called what?
Planetesimals made from ice and sometimes rock are called comets.
What are planetesimals and protoplanets and how are related to one another?

Walter and luis alvarez think that a large rocky object is what?
Walter and Luis Alvarez proposed the theory that a large rocky object, such as an asteroid or comet, colliding with Earth caused the mass extinction of the dinosaurs. This theory is known as the Alvarez Hypothesis.
