What is the top most layer of the earth's surface?

The topmost layer of the Earth's surface is called the crust. It is the outermost solid shell of the Earth and is composed of various types of rocks, minerals, and soil. The crust is divided into two types: continental crust, which makes up the continents, and oceanic crust, which forms the ocean floors. The thickness of the crust varies, with continental crust being thicker than oceanic crust.
