What are the two main causes for the existence of atmospheres on the terrestrial planets?
One main reason is the gravity a dense object like a terrestial planet has. As gravity depends on the density of a object and a rocky planet has much density...our earth is the densest object in the solar system but Jupiter's gravity is more as gravity depends upon size too. The gravity holds the gases forming the atmosphere.
Another reason is the core which has a magnetic effect and forms a magnetic layer which has some effect on the atmospheric gases and saves it from going away to the space by attracting the gases towards the pole where the gravity is the highest.
What else can I help you with?
Why are the terrestrial planets solid?
Terrestrial planets are solid because they are predominantly made up of rock and metal materials that are closer to the sun and have higher temperatures, leading to the formation of solid surfaces. The intense heat from the sun causes volatile compounds to vaporize, leaving behind only the solid materials. Additionally, the gravitational forces of these planets are strong enough to hold onto their solid material structures in close proximity.
Why are gas giants more oblate than terrestrial planets?
Gas planets are just that - gaseous. This means they are less dense, and more susceptible to centripetal forces. Gas planets also have a tendency to have a faster rotation speed due in part to their large mass. The result is slightly oblate spheroids.
What is a common characteristic of all planets in the solar system?
A common characteristic of all planets in the solar system is that they orbit the Sun, which provides the gravitational force necessary to maintain their paths. Additionally, all planets are nearly spherical in shape due to their own gravity, which causes them to pull themselves into a round form. They also have varying compositions, with terrestrial planets being rocky and gas giants composed mainly of gases.
What causes extreme temperature on different planets of solar system?
Extreme temperatures on different planets in the solar system are primarily caused by their distance from the Sun and their atmospheric composition. Planets closer to the Sun, like Mercury, experience higher temperatures due to solar radiation, while those farther away, like Neptune, experience colder temperatures. Factors such as greenhouse gases can also influence a planet's temperature by trapping heat in their atmospheres.
What four inner planets has almost no atmosphere?
The four inner planets, also known as the terrestrial planets, are Mercury, Venus, Earth, and Mars. Among them, Mercury has almost no atmosphere due to its small size and proximity to the Sun, which causes any gases to escape easily. Mars has a thin atmosphere, primarily composed of carbon dioxide, but it is much less substantial than Earth's. Venus has a thick atmosphere, so it does not fit the criteria of having almost no atmosphere.
Why do planets with atmospheres have less impacts?
The atmosphere causes the object that is impacting or hitting the earth and causes it to burn and deteriorate as it lands on the earth's Surface.

What are the causes for depletion of terrestrial ecoystem?
The extra terrestrial organisms are the ones getting depleted. They are due to deforestation.
Can you prove the existence of gravity?
Gravity is a fundamental force that causes objects with mass to be attracted to each other. Its existence is proven through various scientific observations and experiments, such as the way objects fall towards the Earth and the orbits of planets around the sun.

Which planet has no true atmosphere?
Mercury. Its close orbit to the Sun causes extreme temperature variances and prevents it from maintaining any substantial gaseous atmosphere.
What is a bane of one's existence?
A bane of one's existence is a person or thing which causes a significant problem to an individual.
What causes extreme temperature on different planets of solar system?

What causes the planets to revlove aound the Sun?
Gravity.
What causes craters on rocky planets?
Most of the time these are asteroids that connect with the planets at high rates of speed.
What causes planets to spin on their axes?
Planets spin on their axes due to the conservation of angular momentum, which is a fundamental principle in physics. As planets formed from rotating clouds of gas and dust in space, their rotation continued as they condensed and solidified. This spinning motion is what causes planets to rotate on their axes.
