QUESTION 1 1 points Save Answer Why are meteor impact craters NOT preserved well on Earth? In other words, Earth has experienced a lot of meteor strikes, but most of the craters are no longer visible. Why? When a meteor strikes the Earth, it typically creates enough faulting to allow magma to rise up and fill in the crater When a meteor strikes the Earth, it typically punctures the lithosphere. This allows magma to rise up and fill in the crater. O Craters on Earth are gradually filled in. Degradation processes decay (weather) the rocks exposed on the edges of Earth craters, and then erosion processes transport the weathered material into the crater, O All of the other answers are correct, and thus this is the best answer.Explanation / Answer
The option “c” that is when meteors strike the earth the crater are made on the surface of the earth get filled by the material of erosion. This happens because weathering whether chemical or physical is a continuous process on earth and when any depression ( whether cosmic or by other means) gets to the surface the material that is weathered from the edge of the depression used to fill the depression and thus making it invisible in some time ( time period is of the order of geological time scale as weathering, erosion and transportation are slow process). Therfore option “c” is correct.
