Geologists use drill bits with diamonds because diamonds are one of the hardest materials on Earth, making them effective for cutting through hard rock and sediment. The diamond-covered bits can withstand the high pressures and temperatures encountered while drilling into Earth's crust, allowing geologists to access subsurface samples for study and analysis.
The loose material is called sediment. It may include bits of rock, minerals, and organic material like plant and animal remains. This sediment can accumulate in layers over time and eventually become sedimentary rock through processes like lithification.
The dropping off of bits of eroded rocks is called deposition. This process occurs when eroded material is transported by water, wind, or ice and then settles or comes to a rest in a new location.
Geologists use drill bits covered with small diamonds because diamonds are the hardest natural substance and can effectively drill through hard rocks in the Earth's crust. The diamonds on the drill bits help to create a clean and precise hole without getting worn out easily compared to other materials. This allows geologists to obtain core samples for studying the composition and structure of the Earth's crust.
Clastic sedimentary rock is sedimentary rock that is formed from rock particles.
The pyroclastic material and bits of rock can get into your lungs and cut up your lungs.

the diamonds are the strongest natural material on earth. these drills can drill through anything

The earth is round, due to gravity, so there are no flat bits at the top and bottom.
Conservation of angular momentum. The rotational velocities of the material coalescing to form the nascent earth 4.6 billion years ago would have been preserved, adding their own little bits to the final result.
The only tool that uses drill bits is a drill. There are, however, many different types of drill bits. The drill bits vary by material, size, shape, and function.

No, but you often have bits of hard material surfacing in the socket which you can pick out. You would be forgiven for thinking it's bone. Your tooth is actually sort of cemented into the bone, for want of a better description, and it's bits of this material that you are seeing. I have personally had bits surfacing for a week after.
"Scientists think that about 4.6 billion years ago, Earth formed as bits of material collided and stuck together" so over the next couple of years the earth formed the inner core, outer core, mantle, crust, lithosphere, and the asthensphere.
