What are 3 reasons why most craters left on earth are no longer visible?
Erosion: One of the primary reasons why many craters on Earth are no longer visible is due to erosion. Natural processes like wind, water, and ice can wear down the surface of the Earth over time, gradually filling in or smoothing out craters. For example, rainwater can erode the edges of craters, causing them to lose their distinct shape and eventually become indistinguishable from the surrounding terrain. In regions with active geological activity, such as tectonic activity or volcanic processes, the surface can be reshaped relatively quickly, further obscuring the features of old craters. Vegetation and Biological Activity: The growth of vegetation and the activities of various organisms can also contribute to the disappearance of craters. Plant roots can penetrate into the soil, breaking apart and filling in the depressions left by impacts. Burrowing animals and insects can further disturb the terrain, altering the appearance of craters over time. In some cases, the growth of forests or other dense vegetation can completely cover up smaller craters, making them difficult to detect. Geological Processes: Earth's dynamic geological processes can gradually bury or alter the appearance of craters. Sediment deposition from rivers, oceans, and glaciers can accumulate over time, burying craters and changing the landscape. Earthquakes, volcanic activity, and tectonic movements can also reshape the surface, potentially concealing or altering the appearance of craters. Additionally, processes like landslides and sedimentary layering can obscure craters by covering them with new materials. These factors, often working in combination, contribute to the fading or complete disappearance of many craters on Earth's surface over geological time scales. However, larger and more recent impact craters can still be visible if they haven't been significantly affected by these processes.

Why is Meteor Crater in Arizona still visible when most impact craters created by meteorites hitting Earth are not?
The Barringer Meteor Crater near Winslow, Arizona is still very distinct and visible, when other craters are worn away, for a couple of reasons. 1. Meteor Crater is relatively young; about 50,000 years old. The worst of the "intense early bombardment", when many of the Moon's craters were formed, was 3 BILLION years ago, and those early few eons used up most of the available rocks in near-Earth space. Those craters are mostly long gone. 2. Arizona is a desert, and has been since the end of the last ice age. There are few rainstorms, no floods, not a whole lot of natural erosion going on.
What is the name of the 3 craters that have been named after the Apollo 11 astronauts?
They were Neil Armstrong , Edwin Aldrin, and Michael Collins.
How are the moons craters named?
[1] The International Astronomical Union decides the names for craters on our Moon. [2] The IAU organizes the naming of each particular feature around a particular theme. [3] The names of craters tend to fall into two groups. Typically, it has been for deceased scientists, scholars, explorers, and artists who've become known for their contributions, be they fundamental or outstanding, to their respective fields. [4] But the craters around Apollo crater and the Mare Moscoviense are to be named after respectively decreased American astronauts and Russian cosmonauts.
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
What are three factors that will affect the future of the biosphere?
1- recognize a change in the environment . 2-determine the cause f that change . 3-change behavior to have a positive impact.
Mercury's cratered surface is indicative of 1. A lack of a sustancial atmosphere 2. greater bombardment by asteroids than other planets away 3. impact by solar particles 4 its small size?
The most correct answer would be #3 because without solar particles, there probably would be no craters regardless of the other factors. A substantial atmosphere would reduce the number of craters by causing the particles to burn up on entry, The remaining craters would be quickly eroded by a substantial atmosphere as they are here on earth.
