Moving an object by its transform directly in update will bypass the Fixed loop Unity uses for collisions. Bear in mind that some scenery is created with software like Maya and such and the artist did not use the origin point (0,0,0) to create his/her scenery. As said in the docs 'Adding a Rigidbody component to an object will put its motion under the control of Unity's physics engine. Colliders are components that define the shape of an object for the physics engine to use in calculations. The ground needs a collider component attached to it so the physics engine can prevent it penetrating the ground.
