The interior of the Earth, like that of the other terrestrial planets, is chemically divided into layers. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. The crust is separated from the mantle by the Mohorovičić discontinuity, and the thickness of the crust varies: averaging 6 km under the oceans and 30–50 km on the continents.

The geologic component layers of the Earth are at the following depths below the surface:

km - name
0–60 - Lithosphere (locally varies between 5 and 200 km)
0–35 - Crust (locally varies between 5 and 70 km)
35–60 - Uppermost part of mantle
35–2890 - Mantle
100–700 - Asthenosphere —
2890–5100 - Outer core
5100–6378 - Inner core

The internal heat of the planet is most likely produced by the radioactive decay of potassium-40, uranium-238 and thorium-232 isotopes. All three have half-life decay periods of more than a billion years. At the center of the planet, the temperature may be up to 7,000 K and the pressure could reach 360 GPa. A portion of the core's thermal energy is transported toward the crust by Mantle plumes; a form of convection consisting of upwellings of higher-temperature rock. These plumes can produce hotspots and flood basalts.

Simply put:
Rock is heavier than water.
Below water, rock, except in crevasses in the rock,
where water seeps down.
Put some sand in a glass of water.
It sinks to the bottom, but the water is still there
between the grains of sand.

It depends on your location. If you were for example in Florida (wetlands) under the land is water. if you are in for example Arizona (if you were located where there is no underground waterspring/river) under the land is the mantle (magma). if you were in a lake or ocean, well technically it would be land underneath you only it is called the ocean floor or lake bottom.

A mixture of very hot liquid Iron and Nickel. This core is responsible for the magnetic field of earth.
