Answer 1

for the first one.
The oceans on Earth formed around 4 billion years ago from water vapor that was accumulated in the atmosphere. Volcanoes spewed out many gases as well as water vapor. Comets and asteroids were also partially made of ice. When they crashed into Earth's surface they added more to the water content.

As the Earth cooled, the water vapor condensed to form clouds, and the clouds rained down the water and created the oceans.
