Tall, cone-shaped mountains in which layers of lava alternate with layers of ash are called
A
shield volcanoes
B
cinder cone volcanoes
C
composite volcanoes
D
lava plateaus
Explanation: 

Detailed explanation-1: -Composite volcanoes are tall, symetrically shaped, with steep sides, sometimes rising 10, 000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders. Famous composite volcanoes include Mount Fuji in Japan, Mount Shasta and Mount Lassen in California, Mount St.

Detailed explanation-2: -A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra.

Detailed explanation-3: -Composite volcanoes are also called stratovolcanoes. Some geologists avoid the use of the term “stratovolcano” because these volcanoes typically are not stratified and do not consist of orderly layers of lava flows and pyroclastic deposits.

Detailed explanation-4: -Stratovolcano: A large, steep-sided, symmetrical cone built of alternating layers (strata) of lava, ash, cinders, blocks, and bombs. Also called composite volcano, these stratovolcanoes form some of Earth’s grandest mountains rising as much as 8, 000 feet above their bases (movie).

Detailed explanation-5: -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. Mount Fuji in Japan and Mount Shasta in California are examples of composite volcanoes.
