if we remove all of Earth's seas and oceans it would no longer be a sphere,since the water all over covers it ,it appears a sphere,right?

Yep. At 6 miles, it is a mere 1300th of the Earth's diameter. On an apple, that would be a dent less than a tenth of a millimeter.monty37 said:well ,then even the world's deepest trench would appear too tiny on earth(without ocean) as a whole huge surface
If Earth were to lose all of its oceans, it would no longer be a sphere and would instead be a smooth, rocky planet. The shape of the planet would be determined by its rotation and the force of gravity, resulting in a bulging at the equator and flattening at the poles.
The absence of oceans would greatly impact Earth's climate. Oceans play a crucial role in regulating the planet's temperature through their ability to absorb and release heat. Without oceans, the temperature fluctuations would be more extreme, resulting in hotter days and colder nights.
It is unlikely that complex life forms could survive on Earth without oceans. Oceans provide a habitat for countless species and play a vital role in the planet's food chain. Without oceans, the Earth's atmosphere would also be significantly different, making it difficult for life to exist.
Oceans play a crucial role in shaping the Earth's surface through erosion, sedimentation, and plate tectonics. Without oceans, these processes would be greatly altered, resulting in a vastly different geological landscape. Mountains, valleys, and other landforms would also be affected.
While there are many factors that could potentially lead to the loss of Earth's oceans, it is highly unlikely to occur in the near future. The Earth's oceans are constantly replenished through the water cycle, and it would take a catastrophic event to completely remove all of the water from the planet.
