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?
The presence of a magnetic field would signal whether or not the planet had a churning metallic core. Mars does not have a Magnetic field because its core stopped spinning.
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.
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.
Is the planet Mars non magnetic?
Mars has a magnetic field.
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.
What characteristics determine whether a planet or moon can maintain an atmosphere?
gravity and temperature; It needs gravity so it can hold its atmosphere.
Why does the earth has a magnetic field?
Large deposits of iron ore within the planet generate the planet's magnetic field.for protection
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
What is the planets ability to retain an atmosphere depends on?

What can we learn from studying a planet's magnetic field?
The size and fluidity of the core of the planet.
