What factor determines whether a planet has a atmosphere?
The factors that determine whether a planet has an atmosphere or not are mass and temperature. Not exactly... There are two main factors that determine whether a planet can develop and keep an atmopshere and they are the escape velocity of the planet (how fast the object has to go to escape the gravitational pull) and the speed of the molecules in the atmosphere. For example the escape velocity for earth is about 11km/s (25,ooomph) Other factors include proximity to a larger body that can will steal the atmosphere away, and distance to the sun which produces solar wind that can literally blow the atmosphere away.
What observations are needed to tell whether an Earth like planet is geologically alive or dead?
Key observations to determine if an Earth-like planet is geologically alive or dead include studying its surface features for evidence of tectonic activity like mountain ranges or volcanoes, examining its atmosphere for signs of active outgassing from the planet's interior, and analyzing seismic activity or the presence of magnetic fields to indicate a molten core. These indicators can help scientists assess the level of geologic activity on the planet.
If a planet is larger is it weaker or stronger?
A planet's size does not directly determine its strength; rather, strength can refer to various factors like gravitational pull, structural integrity, or magnetic field. Generally, larger planets tend to have stronger gravitational forces due to their greater mass. However, factors such as composition and core structure also play significant roles in determining a planet's overall strength. Thus, a larger planet can be stronger in some respects but not necessarily in others.
How big will a planet be if it is located far from the sun?
The size of a planet is not related to it's distance from the sun. Planet mass and orbital velocity are factors that determine it's distance from the sun.
Is the planet Mars non magnetic?
Mars has a magnetic field.
What is the most powerful planet?
It is subjective to determine the "most powerful" planet, as each planet has unique characteristics. In our solar system, Jupiter is often considered the most powerful due to its immense size, strong magnetic field, and gravitational influence on other planets.
What does the distance between the sun and a planet determine?
The distance between the sun and a planet determines its orbital period, its orbital speed, and the amount of insolation. Other factors such as composition and albedo are required to determine other variables.
How could you test whether the core of another planet were completely solid?
To test whether the core of another planet is completely solid, scientists could analyze seismic data from planetary quakes or impacts, similar to how seismic waves are used on Earth. By studying the propagation of these waves, researchers can determine the core's density and composition. Additionally, magnetometry could provide insights into the planet's magnetic field, indicating whether a liquid outer layer affects the field's properties. Lastly, gravitational field measurements can reveal variations in density that suggest a solid or liquid core.
What characteristics determine whether a planet or moon can maintain an atmosphere?
gravity and temperature; It needs gravity so it can hold its atmosphere.
Does the magnetic field rotate your planet?
no
Imagine a planet with no magnetic field. Such a planet probably does not have a .?
liquid core
As the geology officer on an expedition to a newly discovered Earthlike planet how might you determine whether the planet has a crust composed of plates that move?
As the geology officer on an expedition to a newly discovered Earthlike planet, you might determine whether the planet has a crust composed of plates that move by chains of volcanoes along continental coastlines.
