The earth and the moon have both been hit by asteroids. They've been hit throughout history.
There are no craters on the earth's surface.
Weather, water, and plants work together to erase craters from the earth's surface.

Combine into one sentence.

Although both the moon and earth have been hit by asteroids throughout history, there aren't any craters on earth's surface because of its environment.

Hopefully that's right :))

journalism is the gathering, organizing, and distribution of news -- to include feature stories and commentary -- through the wide variety of print and non-print media outlets. it is not a recent phenomenon, by any means; the earliest reference to a journalistic product comes from rome circa 59 b.c., when news was recorded in a circular called the acta diurna. it enjoyed daily publication and was hung strategically throughout the city for all to read, or for those who were able to read.
