Lakes are primarily formed by rain and runoff. This is because rain, which is a form of precipitation, fills up depressions, crevasses or low-lying areas with water, while runoff from surrounding land areas, including melting snow and ice, also contributes to the formation and sustenance of lakes. Other factors such as geological processes, glaciation, and tectonic movements can also create or influence the formation of lakes. However, out of the given options, rain and runoff are the most relevant factors.<|im_end|>

 Sure, I'd be happy to help! Based on the information provided, lakes are formed by the following options:

* Rain and runoff: Lakes are formed when rainwater and snowmelt collect in a low-lying area and do not drain away quickly enough. This can happen when the land is flat or sloping, and the soil is unable to absorb the water quickly enough. Over time, the water accumulates and forms a lake.

The other options are not correct because:

* Ice wedging: This is a process that occurs in cold climates where ice forms in the soil and rocks, causing them to break apart and create depressions. This can lead to the formation of ponds and lakes, but it is not the primary mechanism for lake formation.
* Hot and cold: This is not a factor in lake formation, as lakes can exist in a wide range of temperatures.
* Condensation: This is the process by which water vapor in the air condenses and forms droplets of water. While condensation can occur in lakes, it is not the primary mechanism for lake formation.
* Rice and beans: This is not a factor in lake formation, as rice and beans are types of food and do not play a role in the formation of lakes.
* Physical weathering: This is the process by which rocks and soil are broken down by physical forces, such as wind, water, and ice. While physical weathering can contribute to the formation of lakes, it is not the primary mechanism.
* Flooding: This can contribute to the formation of lakes, but it is not the primary mechanism. Flooding occurs when water overflows its banks and covers a larger area, and it can create lakes by filling low-lying areas.
* Ice and sun: This is not a factor in lake formation, as ice and sun do not play a direct role in the formation of lakes.

I hope this helps! Let me know if you have any other questions.<|im_end|>
