Minor Gateway (Wizard Spell) 2e

The caster draws in the air a portal or doorway which then briefly opens to one of the four elemental planes, letting the raw energy and material of the plane flow into the world. The portal opens for only a second or two, but in this time it is bi-directional.
Plane of Fire: When the portal opens, a half sphere of heat and energy bursts forth, enveloping everything within 20' in flames and dealing 8d6 points of fire damage. Creatures in the area of effect can save for half damage.
Plane of Air: A strong gust of fresh air rushes out, blowing over anything not firmly attached to the ground. Creatures within 20' must make a strength check to stay on their feet. If there is nowhere for the air to go, for example if the portal is opened in a sealed room, the pressure in the room raises, but there is no wind. If opened in a hallway or other restricted space the effects are intensified, possibly knocking creatures back. 
Plane of Water: 3000' cubic feet (30 x 10 x 10) of fresh water burst forth from the portal. Like a portal to the plane of air, the effects are largely determined by the terrain the portal is opened into.
Plane of Earth: Considering that the plane of earth is solid material, this spell effectively creates a very short lived solid wall.
There is a very small, but non-zero, chance that the portal opens near a denizen of the plane, which may accidentally or intentionally be swept through the portal and into existence. This creature is not bound in any way. DMs should be careful in deciding if and what ever comes through the portal.
