Many nuclear detonations will create a mushroom cloud (especially near the ground due to material from the ground being sucked up into the vacuum created by the explosion, thus forming a large part of the "stem" of the cloud) and if they are near the ground, will create at least a small crater, but it sounds like you are talking about a groundburst detonation (as opposed to an airburst). These types of explosions carry more radioactive debris from the ground into the air and generate a lot of fallout due to the irradiated debris from the explosion.
A low altitude detonation or a groundburst will cause a crater to form. Nuclear detonations that take place near the ground (but not underground) will create a mushroom cloud (this is caused by a Raleigh-Taylor instability). I have noted that a lower level detonation close to the ground will suck up material into the fireball and create a more pronounced stem.
A huge pool of Lava that creates the center. To get to the core you have to go through millions of layers of Lava Rock, basically , don't try and land on the sun becasue you would never survive!
In the exosphere, Friction between the atmosphere and the shuttle creates the heat.

Surface burst, but any nuclear weapon can be capable of doing that.
