Answer to Question 1

The origin of the ocean is linked directly to the origin of the atmosphere. Earth's initial atmosphere was blown out to space by the Sun's solar wind. A second atmosphere was created by outgassing of water vapor (steam), with small amounts of carbon dioxide, hydrogen, and other gases. This water vapor was the primary source of water on Earth, including supplying the oceans with water. Not all water came from inside Earth. Other sources of water, such as asteroids, may have contributed to Earth's oceans as well.

Answer to Question 2

B
