The factors that contribute to long-term climate change from the options you provided include:
- Earth's orbit around the Sun - Changes in Earth's orbit can affect climate patterns over long periods (Milankovitch cycles).
- Solar energy - Variations in solar energy output can influence Earth's climate over long timescales.
- Volcanic eruptions - Large eruptions can release significant amounts of ash and gases into the atmosphere, affecting climate temporarily and potentially contributing to longer-term changes depending on their scale and frequency.
Ice forming on a lake and thunderstorms are not significant factors in long-term climate change; they represent more localized and short-term weather phenomena rather than processes that can shift climate over extended periods.
