1. describe what you see: a comet coming down to earth
2.describe what you see: the moon from a far
3.describe what you see: The dark, flat often circular regions called lunar maria (singular form: mare)
1. impact toward the earth: If the comet is 10 kilometers across or larger (that is, if the impact carries an energy of more than about 100 million megatons), the resulting global environmental damage will be so extensive that it will lead to a mass extinction, in which most life forms die
2. impact toward the earth: The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean w waters face away from the moon and the pull is weakest.
