What evidence indicates that the rings of Uranus have little dust and the rings of Neptune contain a lot of dust?
What evidence indicates that the rings of Uranus have little dust and the rings of Neptune contain a lot of dust? The rings of Uranus appear dark in forward-scattered light, and the rings of Neptune appear bright in forward-scattered light. How does a thin planetary ring retain its shape?
And another question, why are neptune's rings so difficult to observe?
The planet's rings are difficult to see because they are dark and vary in density and size. Astronomers think Neptune's rings are young compared to the age of the planet, and that they were probably formed when one of Neptune's moons was destroyed. What are some reasons why Neptune receives such a small amount of sunlight? The atmosphere Like the other giant planets, Neptune's outer atmosphere is composed predominantly of hydrogen and helium. The temperature of Neptune's atmosphere varies with altitude. Neptune is more than 50 percent farther from the Sun than is Uranus and so receives less than half the sunlight of the latter.
Why are the rings of Neptune dark quizlet?
Uranus and Neptune's rings are very dark indicating they are probably made of organic materials and ices that have been darkened by high-energy radiation. Then, why do we think that ring particles must be replenished over time where we think ring particles come from choose the correct statement? Why do we think that ring particles must be replenished over time? Because collisions are constantly occurring within the ring systems, ring particles are continually being ground down to dust. Dust cannot survive long in ring systems because sunlight pressure makes the particles slowly fall onto the planet.
Also, what is the evidence for the origin of the rings of uranus?
What is the origin of the rings of Uranus? They are made of debris from impacts on Uranus's moons. What is the evidence for the origin of the rings of Uranus? Uranus's rings are trapped among the orbits of small moons and Uranus's moons show evidence of having been impacted. Subsequently, what is neptune's rings made out of? The rings are made up of small rocks and dust. Neptune's rings are not the same thickness all around. There are areas of the rings which are much thicker than other areas of the rings. These thicker parts are called ring arcs.
- What is the evidence from Thomson's experiment that all atoms contain electrons?
The average temperature on Mars is -81 degrees F.
- What indicates that the core of the Earth is a liquid?
Jupiter might destroy the other planets and the asteroid belt when it arrives at the sun. The solar system would be unstable by the time Jupiter got to the sun. The entire solar system would be destroyed.
