What would have made the craters on Mars?
The craters on Mars are primarily caused by asteroid and meteor impacts. Mars has a thin atmosphere that offers less protection from incoming celestial objects compared to Earth, allowing impacts to create craters on its surface over millions of years.
Do craters cover most of the Earth?
No. Earth has relatively few impacts craters.
Why do you think there are millions of impact craters on the moon and so few on Earth?
The Earth has had far more asteroid and meteorite impacts than the moon. Impact craters on Earth however are eroded by the atmosphere and water and also filled in by water and sediment. Since the moon has next to no atmosphere craters tend not to erode so they will always be visable.
Can a asteroid damage a planet?
An asteroid can indeed damage a planet when it strikes it. It is possible that an asteroid strike resulted in the dying off of the dinosaurs on Earth. There are certainly some large craters on Earth that are suggestive of asteroid strikes.
Why does the moon have craters an the earth does not?
The Earth does have craters, but because of the seas and vegetation on land, they are not as noticeable. However there are some that are very noticeable, like the famous one in Arizona. Craters on Earth and the Moon are caused by impacts of meteorites.
What feature can be found on the earth and the moon?
Both the Earth and the Moon have craters, which are depressions on the surface formed by impacts from asteroids or meteoroids. These craters can vary in size and shape, and can provide valuable information about the history of impacts on both celestial bodies.
Large craters found on earth support the hypothesis that impact events have caused?
mass extinction events throughout history. These craters provide evidence of the catastrophic effects of asteroid or comet impacts on the Earth's surface, leading to significant environmental changes and extinction events. Scientists study these craters to better understand the impact events and their potential implications for future planetary protection.
Why does earth's moon preserve all the impacts it has had?
Theres no storms, rain or anything that effects it so it retains the craters no weather to destroy the craters.
Why have very old craters on the moon not be erased as similar craters on earth have been?
Unlike Earth, the moon does not have air, water, glaciers, or plate tectonics to erase craters. The only forces that significantly alter the moon's surfaces are impacts that form new craters.
Why does earth lack craters?
Earth does have impact craters, but it has much few than the moon or Mercury and many of them are not readily visible. The main reason is that Earth has many active geologic processes that renew and change its surface, burying and destroying impact craters. If an impact crater on Earth is clearly visible then it probably formed quite recently in geologic history. Many of the impact craters on the moon and Mercury are billions of years old, dating to when the solar system was young and large asteroid impacts were far more common than they are now. Very little of Earth's crust from that time remains intact. By contrast craters on Earth that are tens of millions of years old are not readily visible.
Has the eath ever been hit by an astroind?
Yes, the Earth has been hit by asteroids in the past. These impacts have been responsible for mass extinction events and have left large impact craters on the Earth's surface. Fortunately, the likelihood of a large asteroid impact in the near future is low due to monitoring and detection efforts.
What cause Craters on Earth?
Asteroids, meteorites or comets are impactors that form impact craters on the Earth and other bodies throughout the solar system. Obviously, the Earth for instance, has to cross an impactor's orbit or vice versa. The size of the impactor hitting the Earth depends on the type of crater that can occur and also the other factors- · the velocity of the impactor · composition of the impactor · composition of the target rock · the strength and porosity of the impactor · angle of impact · gravity of the target planet For more on craters try- www.weirdwarp.com
