From D&D Wiki
 ELEMENTAL PLANE OF EARTH
Many planes fall under the influence of the Elemental Plane of Earth (SRD Planes). These planes share properties in common with this elemental plane, as charted below:
Planes close to this plane have the following traits, corresponding to their closeness to this plane.
- Mildly Earth
- Cast earth spells at +1 caster level.
- Cast air spells at -1 caster level.
- Moderately Earth
- Cast earth spells at +1 caster level. Spell is Extended.
- Cast air spells at 1/2 caster level.
- Strongly Earth
- Enhanced magic. Spells and spell-like abilities that use, manipulate, or create earth or stone (including those of the Earth domain) are both empowered and extended (as if the Empower Spell and Extend Spell metamagic feats had been used on them, but the spells don’t require higher-level slots). Spells and spell-like abilities that are already empowered or extended are unaffected by this benefit.
- Impeded magic. Spells and spell-like abilities that use or create air (including spells of the Air domain and spells that summon air elementals or outsiders with the air subtype) are impeded.
