No, the surface of the Earth is not made of liquid water. The Earth's surface is made up of:

* Land: This includes continents, islands, and mountains. It's mostly made of rock.

* Water: This includes oceans, lakes, rivers, and ice. It covers about 71% of the Earth's surface, but it's not the entire surface.

While water covers a large portion of the Earth, the actual surface is a combination of land and water.
