It is commonly stated that a planet's atmosphere acts as a sort of shield against impacts. It is only partially true. Small meteoroids will burn up in the atmosphere while some larger objects will break into fragments that then reach the surface at much lower speeds.
Large asteroids and comets, on the other hand, are largely unhindered by even a thick atmosphere. These are the objects that leave craters that are plainly visible from space. When impact craters do form, however, the presence of an atmosphere may cause erosion and movement of sediment that can wear down and bury impact craters.
What else can I help you with?
Is impact cratering visible on the planet Venus?
Yes, but there are not so many craters, per square kilometer,as on the Moon.
What planet is full of impact craters and and no atmosphere?
I think it is Mercury.
What are four stages of planetary development?
The four stages of planetary development are accretion, differentiation, impact cratering, and tectonics. During accretion, dust and gas combine to form planetesimals that eventually collide to form a planet. Differentiation occurs as heavy materials sink to the planet's core and lighter materials rise to the surface. Impact cratering involves the formation of craters due to collisions with other celestial bodies. Tectonics refers to the processes that shape the planet's surface, such as plate movements and volcanic activity.
The resulting scar from asteroids or comets strikes are called?
The resulting scar from asteroid or comet strikes is called an impact crater. These craters are formed when the meteorite collides with the surface of a planet or moon, causing a depression in the ground.
Can a comet impact a planet?
Yes, anything in space can hit a planet if its strong enough to get past the atmosphere.
What are four processes that change the surfaces of terrestrial planets?
Impact cratering: Collisions with asteroids or comets create craters on the surface. Tectonism: Movement of the planet's lithosphere causes features like mountains and valleys. Erosion: Weathering and transportation of materials by wind, water, or ice alters the landforms. Volcanism: Eruptions of molten rock from the planet's interior build up volcanic features like mountains and lava flows.
Does Uranus have any impact cratering on it?
No way to tell as the entire planet is shrouded in clouds. But, having said that, many of its moons (e.g., Titania and Oberon) have impact craters. So it's not a far reach to believe that Uranus itself would have impact craters in its rocky central core.
What are 4 types of processes that shape planets?
Four types of processes that shape planets are impact cratering (from collisions with other objects), tectonics (caused by the movement of the planet's crust), erosion (by wind, water, or ice), and volcanic activity (from eruptions of molten rock from the planet's interior).
For planets of similar size but with one planet more massive than the other which planet is more likely to maintain an atmosphere explain?
The more massive planet is more likely to maintain its atmosphere because its stronger gravity can hold onto the gases in its atmosphere better. The gravitational pull of the heavier planet can prevent gases from escaping into space, resulting in a more stable atmosphere compared to the lighter planet.
Does a planet need an atmosphere?
No. The planet Mercury does not have an atmosphere.
What the terrestrial planet that has no atmosphere?
what is the terrestrial planet that has no atmosphere
What is the atmosphere of the planet called Ceres?
Ceres is not a planet; it is a dwarf planet. It does not have an atmosphere.
