2019年9月1日 · Composite volcanoes, also called stratovolcanoes, are cone-shaped volcanoes built from many layers of lava, pumice, ash, and tephra. Because they are built of layers of viscous material, rather than fluid lava, composite volcanoes tend to form tall peaks rather than rounded cones.

2024年6月30日 · A stratovolcano or composite volcano is a large, steep-sided volcano that consists of multiple layers of hardened lava, tephra, pumice, and volcanic ash. These volcanoes have a conical shape and produce periodic, often explosive eruptions.

Composite cones are large volcanoes (many thousands of feet or meters tall) generally composed of lava flows, pyroclastic deposits, and mudflow (lahar) deposits, as well as lava domes. Composite volcanoes are active over long periods (tens to hundreds of thousands of years), and erupt periodically. Composite volcanoes are also called ...

2024年2月19日 · Composite volcanoes, also known as stratovolcanoes, are long-lived, relatively large, tall, conical-shaped mountains with steep sides. These volcanic landforms are made of interlayered solidified lava and pyroclasts.

A stratovolcano, also known as a composite volcano, is a typically conical volcano built up by many alternating layers of hardened lava and tephra. [1] Unlike shield volcanoes , stratovolcanoes are characterized by a steep profile with a summit crater and explosive eruptions. [ 2 ]

A composite volcano, also known as a stratovolcano is a cone-shaped volcano built from several layers of lava, pumice, ash, and tephra. Due to its viscous lava, a composite volcano tends to form tall peaks rather than rounded cones.

2024年2月7日 · Composite Volcanoes: Composite volcanoes, also referred to as stratovolcano, are a type of volcano that has a distinctive shape and also eruptive characteristic. These volcanoes are tall, steep-sided cones and are formed through a combination of both explosive as well as effusive volcanic activity.
