Question

which volcano is the least explosive a.composite b. cinder cone c. lava d.shield

Answer 1

Answer:

which volcano is the least explosive

a. composite✅

Explanation:

The least explosive type of volcano is called a basalt plateau. These volcanoes produce a very fluid basaltic magma with horizontal flows. The form of these volcanoes is flat to gently sloping and they can occupy an area from 100,000 to 1,000,000 square kilometers.

Answer 2

A volcano is shown as a crack in the crust of the earth. Lava and volcanic ash usually emanate from this aperture. Liquid magma encompasses molten gases that tend to expand via cracks in the Earth's crust beneath a volcano.

• Option D. Shield volcanoes is the correct one as spew out a fluid liquid called lava that flows with ease. Lava often forms into the shape of a shield as it spreads. There is little viscosity in this volcano. Therefore, shield explosions must not be explosive. Therefore, this type of volcano is considered to be the least violent.
• Option A is wrong because composite cones or volcanoes are among the world's most dangerous volcanoes. They frequently produce eruptions that collapse on themselves rather than creating any lofty structures, and these collapsed depressions are known as calderas. This is because they are typically so explosive.
• Because the cinder cone volcano is smaller than the composite volcano but cannot be classified as a least violent volcano, option B. is erroneous.
• Option C is untrue since lava flows rarely result in fatalities because they travel slowly enough to allow people to avoid them.

The correct answer is a shield volcano, option d. The least explosive type of volcano is the shield volcano.
