Natural phenomena are events or processes that occur in nature without human intervention. Examples include earthquakes, volcanoes, and tornadoes, which result from the Earth's geological and atmospheric activities. These events can have significant impacts on the environment and human life. Other natural phenomena include weather patterns, such as rainbows and thunderstorms, which are caused by the interaction of sunlight and moisture in the atmosphere. Additionally, ocean currents and tides are influenced by the gravitational pull of the moon and sun, affecting marine ecosystems and coastal regions.
