What are some tips for discovering combinations that involve geological formations in Little Alchemy 2?

In Little Alchemy 2, discovering combinations involving geological formations often requires experimenting with elements related to the Earth, time, and natural processes. Here are some tips and specific combinations to help you uncover geological elements:

General Tips for Geological Combinations
1. Start with Basic Earth Elements: Many geological formations stem from basic elements like Earth, Stone, Lava, and Pressure. Always keep these in mind when experimenting.
2. Use Time and Pressure: Geological formations often involve the passage of time or the application of pressure. Combine elements like Time, Pressure, or Earth with other materials to see what forms.
3. Think About Natural Processes: Consider how geological formations are created in real life (e.g., erosion, volcanic activity, sedimentation) and try to replicate these processes in the game.
4. Experiment with Layers: Some geological formations are created by layering materials over time. For example, combining Stone with Stone or Earth with Earth can lead to new discoveries.

Tips for Experimentation
- Use the Hints System: If you're stuck, the in-game hints system can guide you toward new combinations.
- Think Outside the Box: Some geological formations require combining seemingly unrelated elements. For example, Time and Pressure are often key to creating geological elements.
- Reuse Elements: Many geological formations can be used to create other elements. For example, Mountain can be combined with Water to create a Lake.
