The inner core; outer core; mantle; and crust
the core is the most dense because it has all the other layers pushing on it.
A Different Answer:
Scientifically, the Lithosphere is the least dense because it has no pressure from other layers against it. It is the crust and the upper mantle.
The Asthenosphere is known as the "weak sphere" and it is under the Lithosphere which has more density from the pressure.
The Mesosphere is the middle sphere. It is the stronger lower mantle. It is under the Asthenosphere and the Lithosphere. It has even more density.
Under that is the outer core, which is liquid iron and it is 2,200 Km thick (very, very thick).
Lastly there is the inner core, which is the most dense of all with all of the other layers pressing against it!
If you want to make all of the info I have listed easier/simpler here it is:
The crust, the mantle (67% of Earth's mass) and the core, made mostly of iron and other dense materials.
Core: 15 million K (27 million degrees F)
Radiative zone: 2 to 7 million K (13.5 to 3.5 million degrees F)
Convective zone: 1 million K (1.8 million degrees F)
Photosphere: 6,000 K (10,000 degrees F)
Chromosphere: 6,000 to 20,000 K (10,000 to 35,500 degrees F)
Sunspots: 4,000 K (6,700 degrees F)
Corona: 1-2 million K (1.8 to 3.6 million degrees F)
The 3 layers of the earth based on their composition are the core; the center layer of the earth,
there is an inner and outer core which are on top of each other. The middle layer of the earth is
the mantle; it is a rocky shell about 2,890 km (1,800 mi) thick that constitutes about 84 percent
of Earth's volume, there is an upper mantle and a regular mantle these mantles are top of each
other; some people say that the mantle contains lava, or some hot liquid. The crust of the Earth
is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is rock,
it it is the outer layer of the earth.
Solar prominences, solar flares, sunspots, and coronal mass ejections :)
The sun'slayers are the core the photsphere and the corona.

The sun is an interesting and vital star. On its surface three things that can be found are sunspots, solar flares, and prominences.
Features on or just above the suns surface include sunspots, prominences, and solar flares.
