Getting to Know: Effects of Volcanoes
... Volcanoes can also impact Earth’s atmosphere. When a large plume of ash enters the atmosphere, it can block sunlight from reaching Earth’s surface. This can cause global temperatures to drop and affect climate. Volcanic eruptions can also release carbon dioxide, which is a greenhouse gas. If too muc ...
