Is Triton an irregular moon?
The term does not refer to shape: Triton is a round moon, but is considered irregular due to its orbit. The largest of each planet are Himalia of Jupiter, Phoebe of Saturn, Sycorax of Uranus, and Triton of Neptune.
What are the factors that affect the size of an impact crater?
The size and shape of a crater depend on several factors:
- the mass of the impacting object;
- the density of the impacting object;
- the velocity of the impacting object; and.
- the geology (type of rock) of the surface the object strikes.
How does impact craters look like?
In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins.
What are 4 or more factors that affect the appearance of impact craters?
The factors affecting the appearance of impact craters and ejecta are the size and velocity of the impactor, and the geology of the target surface.
What 2 factors controls the size that an impact crater will have?
2. What factor controls the size that an impact crater will have? The size, mass, speed, and angle of the falling object determine the size, shape, and complexityof the resulting crater. Small, slow-moving objects have low impact energy and cause small craters.
What are the 7 features of an impact crater?
The features that best determine an impact origin for a crater are (1) a circular rim crest outline, (2) flanks that gently rise [76] above the surrounding terrain, (3) floors with elevations lower than those of the surrounding terrain, (4) an ejecta blanket surrounding the crater, and (S) an inner basin that may be …
Which one made the deepest impact crater?
Specs: Also known as the Vredefort Dome, the Vredefort crater has an estimated radius of 118 miles (190 kilometers), making it the world’s largest known impact structure.
How do impact craters form?
Craters produced by the collision of a meteorite with the Earth (or another planet or moon) are called impact craters. The high-speed impact of a large meteorite compresses, or forces downward, a wide area of rock. The pressure pulverizes the rock. Most of the material falls around the rim of the newly formed crater.
What are the four types of craters?
The Moon holds craters, basins, mountains, rilles, and rays. Each has its own attributes, but all are related to impacts in some way. Lunar impact craters come in three basic types: simple craters, complex craters, and basins. Simple craters are what most people think of when they visualize a crater.
Why is it so difficult to find craters on Earth?
On Earth, impact craters are harder to recognize because of weathering and erosion of its surface. The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth’s surface and erase all but the most recent impacts.
Which planet has the most craters?
List of largest craters in the Solar System
| Body | Crater | Crater diameter |
|---|---|---|
| Mercury | Rembrandt | 715 km (444 mi) |
| Venus | Mead | 280 km (170 mi) |
| Earth | Vredefort | 250–300 km (160–190 mi) |
| Sudbury Basin | 250 km (160 mi) |
What planet has the largest volcano?
Mars
What was the last supervolcano to erupt?
Taupo
What planet has 10 rings?
In addition, dust bands observed between the main rings of Uranus may be similar to the rings of Jupiter. In contrast, the Neptunian ring system is quite similar to that of Uranus, although it is less complex, darker and contains more dust; the Neptunian rings are also positioned further from the planet.
What effect creates gaps in the rings around a planet?
The wider Encke gap is caused by the gravity from a moon called Pan. Pan orbits Saturn within the Encke gap; its gravity causes ring “inside” particles (closer to Saturn) to be pushed into smaller orbits, and “outside particles (farther from Saturn) to be pushed into larger orbits, resulting in the Encke gap.
