It would be like the rest of earth, mountains etc.
No, mars don't have oceans like on earth.
The Earth is round with oceans and continets.
Life on Earth without oceans would mean no water cycle, impacting weather patterns and climate regulation. Marine life would cease to exist, affecting food chains and biodiversity. Coastal regions and ecosystems would be drastically altered, potentially leading to widespread species extinction.
Earth's oceans would lose their tides and the debris would form rings around the Earth, just like the outer planets have.
From the moon, you would see Earth in the sky as a bright blue and white sphere. You would not be able to see specific details like buildings or people, but you may be able to see continents, oceans, and clouds. The view would be quite spectacular and awe-inspiring.
The ocean is the major factor of heat, and delivers warm air to where ever the current takes it. It will be much colder, winters will be nasty as there are no warming influences of the oceans. Also, it will be much drier with a significant decrease of rainfall. The oceans are a major factor of rainfall. Without an ocean, ice would cover 15-23 per cent of the earth. Deserts would dominate the equator regions, and everywhere else would be COLDER and DRIER.
The only astronomical effects on the Oceans would be Tides, which put simply would read like this.'Tides are the rise and fall of sea levels caused by the combined effects of the rotation of the Earth and the gravitational forces exerted by the Moon and the Sun.'
The moon does not have oceans like Earth. However, there may be underground reservoirs of water ice in some areas of the moon's surface.
Of course. The lunar "maria" were observed by Italian astronomers, who decided that they must be oceans on the moon, just like oceans on Earth, so they referred to them as 'oceans' or 'seas' ... one 'mare', two or more 'maria' in Italian. We have several of them on Earth, and another one in "West Side Story".
Because it doesn't have oceans . . . And the question should be, "Why DOESN'T the moon appear blue like Earth?"
Yes but not enough for you to notice like the oceans.
Well considering the fact that a lot of x-ray and UV radiation from the Sun is absorbed here, a lot of people on Earth would get cancer and other diseases.
