sea level
It is the average height of the surface of the oceans of the world.
Roughly 70% of Earth's surface is covered by oceans, which means that 70% of the surface is below sea level.
The word is sea level.
About 29% of Earth's surface is above sea level, with the remaining 71% covered by oceans.
Hi, Here Is The Answer Sea level is the height of the surface of the world's oceans
Approximately 29% of Earth's surface is above sea level, while the remaining 71% is covered by oceans.
Sea level is a global average level of the world's oceans, measured at a specific point on the Earth's surface, and it is not confined to any particular state.
No, sea level is defined as an average level for the surface of one or more of Earth's oceans. Land elevations can vary around sea level, but sea level itself is determined by the average height of the ocean's surface.
The oceans surface is 100% water.
Because the oceans are at sea level and the rivers are always above sea level, meaning that water flows downhill.
The oceans form most of the surface of the World.
