Arthritis. Bones are normal separated by a cushioning on their ends called cartilage, which is the substance that allows bones to glide gently over one another (such as the knee or elbow joint, and this meeting of two bones is called an "articulation"), when this cartilage is lost the bones come into contact with each other this is known as arthritis.
Yes, if the cartilage is damaged. It doesn't necessarily hurt. It can make a grinding or clicking sound.
A plate boundary is the term for when two tectonic plates rub together. Tectonic plates are solid rocks that make up the Earth's crust.

tectonic hazards are where two plates rub together
A fault line is a place where two plates rub together. This tectonic activity can cause earthquakes both on dry land and underwater. When it happens underwater, it can create a tsunami.
Earthquakes are caused when pressure builds up as two tectonic plates move together. As the pressure is released, an earthquake is produced.
they form mountains, volcanoes, earthquakes.
Seismic waves originate along fault lines because that is an edge of a tectonic plate. Imagine the tectonic plates as pieces of a puzzle. The fault line is the wavy side or edge in the piece and the pieces fit together. Whenever the plates move, they rub against the tectonic plates or puzzle pieces on their sides creating seismic waves.

Beacause plates, at tectonic, boundaries shift against each other.

Yes, and, no. Yes, waves are created by tectonic plates during an earthquake (When two or more tectonic plates rub together and make huge vibrations) and even cause tsunami waves. Waves are not formed when the plates are still, though.
It was a conservative earthquake caused by tectonic plates under ground, that rub together to make friction.
they form mountains, volcanoes, earthquakes.
Earthquakes occur in Kobé because it is built between 2 tectonic plates, that's why when there is an earthquake the ground splits in half, that crack is the gap between the tectonic plates when they rub together, this is called a conservative boundary. I hope this answer has been of much use.
I'm afraid I only know the cause. When the edges of the tectonic plates rub together it causes vibrations, that is the earthquake.
They rub together and send shock-waves outward from the epicenter due to friction between the two plates.
an earthquake happens
No. Everything lies on a tectonic plate. Cities that lie near where 2 tectonic plates meet have earthquakes. Tectonic Plates expand and contract, and it is often that they expand and rub against each other. As they rub, they may overlap and cause an earthquake. Obvioulsy, a city directly above where they overlap will feel it more than a city which is in the middle of a tectonic plate.
