What are the oceans made out of?
seawater water that makes up the oceans and seas covering more than 70 percent of Earth’s surface.

Why was the ocean made?
As temperatures cooled the surface solidified and an atmosphere was created.

Which of these scenarios is responsible for the majority of water in the oceans is still unclear but we know that most of the water in the oceans (and on the rest of the planet) is very ancient – on the order of 4 billion years old.
What is the difference between a sea and an ocean?
Can you drink ocean water?
Drinking seawater can be deadly to humans.
Seawater contains salt. When humans drink seawater their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt the salt content in seawater is much higher than what can be processed by the human body.

When a star runs out of hydrogen fuel in its core the core has to get hotter in order to fuse the next element helium.

Now University of Utah chemists may have solved one enigma by showing how cold water can get before it absolutely must freeze: 48 degrees below zero Celsius (minus 55 Fahrenheit). That’s 48 degrees Celsius (87 degrees Fahrenheit) colder than what most people consider the freezing point of water namely 0 C (32 F).
Does water have DNA?
River water lake water and seawater contain DNA belonging to organisms such as animals and plants. Ecologists have begun to actively analyze such DNA molecules called environmental DNA to assess the distribution of macro-organisms. … In a natural environment these processes can operate in a complex way.
