Every year, approximately 60 volcanoes on Earth become active. Some release large amounts of gas, ashes, and dust into the atmosphere. Blown by winds, these particles may float around in the atmosphere for months, even years. Forming clouds, the volcanic material stops some of the Sun's rays from reaching Eartha's surface. This can cause a slight drop in temperatures worldwide. | |
