Ecuador
Ecuador's capital is Quito, which is in the province of Pichincha in the Sierra region. Its largest city is Guayaquil, in the Guayas Province. Cotopaxi, just south of Quito, is one of the world's highest active volcanoes. The top of Mount Chimborazo (6,268 m, or 20,560 ft, above sea level), Ecuador's tallest mountain, is the most distant point from the center of the Earth on the Earth's surface because of the ellipsoid shape of the planet.
Chimborazo
Chimborazo is an ice-capped inactive volcano in Ecuador. Chimborazo is a double volcano composed of one volcanic edifice on top of another. Chimborazo shows four summits; Whymper, Veintimilla, Politecnica, and Nicolas Martínez. The Whymper peak is the highest point on the mountain at 6,263 meters. The Veintimilla peak is about high. The Politecnica peak is high. The last peak, Nicolas Martínez, is high and was named after the father of Ecuadorian mountaineering. The volcano is categorized as a stratovolcano. This type of volcano is characterized as having low slopes at the bottom that gradually get steeper the higher up the mountain. Chimborazo has a circumference of and a diameter of . Chimborazo's upper elevations are covered in glaciers that are decreasing in size due to climate change and falling ash from the nearby volcano, Tungurahua. In addition to the glaciers, the volcano is covered with craters. The volcano is dominantly andesitic to dacitic. This means that the lava is blocky, or flowing down the sides of the volcano, or somewhere in between.
