The answer to this multiple-choice question was a torpedo. The reason that the question specifies "usually" is that ASW aircraft can launch torpedoes.
(The word missile in military usage always means self-propelled weapons.)
The ASROC is a rocket-boosted torpedo, and many other types of missiles are launched from ships and submarines, including cruise missiles such as the Tomahawk. Trident (FBM) submarines can launch strategic ICBMs.
*All submarine weapons are actually ejected from the vessel prior to its activation: torpedoes are ejected by water impulse, as are SUBROC, Harpoon, and Tomahawk missiles. Their motors start once they've cleared a certain range from the vessel. Ballistic missiles are ejected by air impulse - launch is near the surface, and the missile is ejected into a pocket of air or steam where the rocket motor ignites.
In the American submarine force their are two types of missiles: 1. Tomahawk® Land Attack Missile (TLAM) 2. Sea-launched ballistic missile (SLBM) A multiple independently targetable reentry vehicle (MIRV) warhead is what is deployed on a SLBM. The TLAM can carry a conventional warhead or a single nuclear warhead.
An installation (usually a group of several underground silos) from which rockets bearing nuclear warheads under their nosecones can be launched.
No. An RPG is a hand held shoulder launched anti-tank weapon.
Usually by inflating bags that have been placed inside the submarine.
A submarine is used as a subsurface naval weapons platform, or as a tool of exploration and recreation. The latter may be manned or robotic, and have a wide range of characteristics and applications. They are usually operated from or with direct reliance on a support vessel of some kind. We've seen them carrying investigators to the deepest oceans, or surveying shipwrecks on the bottom of the sea. The former are usually sophisticated naval vessels capable of great range and extended independent operation. They can carry torpedoes to sink other vessels, or guided missiles to be launched at distant targets to deliver nuclear payloads. The newer munitions include cruise missiles which can be launched from the submarine, or anti-ship missiles which can also be launched from below the surface. Certainly there are a number of instances of "spooks" working with the submarine service in a number of espionage or "black ops" projects. It could be the insertion of a SEAL team, or the gathering of intelligence in various ways.

A tricycle (usually propelled by pedalling); used in the Orient for transporting passengers for hire.

Submarine means occurring under the sea, so a submarine landslide is one that occurs under the sea, usually due to undersea earthquakes and the shifting of tectonic plates.

In general, yes, a submarine is larger than a submersible. A submersible is usually considered to be a small craft operated from a support vessel.
Modern research submarines can usually carry two, three or four. There are anywhere from about 100 people on a U.S. Navy attack submarine to over 200 on one of our fleet ballistic missile boats. And some of the small early WWII boats had crews of something on the order of 60 or so. The Japanese used 2-man subs at Pearl Harbor. Bottom line: the number of crew required to operate a submarine varies with the type of boat. Need a link? You got it.
