The reason why Venus has fewer craters as compared to Earth’sMoon
Answer to Problem 1RQ
The indication of the small number of craters on Venus is because the entire crust that has been replaced with a new crust in the last half billion years.
Explanation of Solution
Introduction:
In the last half billion of year, the entire crust of the crater has been replaced and the old crust has got covered by the lava that has flowed over it.
It is believed by scientists that the old craters of Venus were covered and filled by massive volcanic events that happened on Venus and erased all the existing craters by filling them with lava. As a result, Venus has a smaller number of the craters than the Earth’s Moon.
Conclusion:
The cratersthat existed on Venus got filled by massive volcanic activities. Hence, Venus has a smaller number of craters as compared to Earth’s Moon.

- Which of the following is least reasonable regarding impact craters? Group of answer choices The size and shape of the crater and the amount of material excavated depends on factors such as the velocity and mass of the impacting body and the geology of the surface. Craters are most often are circular but more elongate craters can be produced with impactors striking the surface at very low angles. The Moon has more craters than the Earth because of its strong tidal force on the impactors. Objects from space typically hit Earth at about 20 km/s ande produce craters that can be approximately 20 times larger in diameter than the impacting objects. The faster the incoming impactor, the larger the crater.arrow_forwardWhy does the Moon create tidal bulges on both sides of Earth instead of only on the side of Earth closest to the Moon?arrow_forwardWe have seen how Mars can support greater elevation differences than Earth or Venus. According to the same arguments, the Moon should have higher mountains than any of the other terrestrial planets, yet we know it does not. What is wrong with applying the same line of reasoning to the mountains on the Moon?arrow_forward
