Which of these are features of most stratovolcanoes?(1 point)

Question

Responses

gentle slope near the base with somewhat quiet eruptions
gentle slope near the base with somewhat quiet eruptions

gentle slope near the top with thin, quickly flowing lava
gentle slope near the top with thin, quickly flowing lava

steep sides near the base with sudden, violent eruptions
steep sides near the base with sudden, violent eruptions

steep sides near the top with thick, slow-moving lava

Answer 1

Stratovolcanoes, also known as composite volcanoes, typically have the following features:

• Steep sides near the top with thick, slow-moving lava
• Sudden, violent eruptions due to the high viscosity of the lava

Therefore, the correct response from the options provided would be:

steep sides near the top with thick, slow-moving lava.

This is characteristic of stratovolcanoes as they often have a conical shape with steep sides and are associated with explosive eruptions.

Answer 2

Which statement correctly describes most cinder cone volcanoes?(1 point)
Responses

They emit lava that slowly spreads before cooling.
They emit lava that slowly spreads before cooling.

They have a single, symmetrical cone at the top.
They have a single, symmetrical cone at the top.

They are one of the tallest types of volcanoes.
They are one of the tallest types of volcanoes.

They often take thousands of years to form.

Answer 3

The statement that correctly describes most cinder cone volcanoes is:

They have a single, symmetrical cone at the top.

Cinder cone volcanoes are characterized by their steep, conical shape and are typically built up from the accumulation of volcanic ash, cinders, and other volcanic debris that fall around a single vent. They are usually smaller in height compared to stratovolcanoes and shield volcanoes, and they form relatively quickly, often in just a few years.

Answer 4

Which of these is a feature of most shield volcanoes?(1 point)
Responses

violent eruptions
violent eruptions

broad base
broad base

thick lava
thick lava

steep sides

Answer 5

A feature of most shield volcanoes is:

broad base.

Shield volcanoes are characterized by their wide, gently sloping sides and broad bases, which are formed by the eruption of low-viscosity lava that can flow over long distances. They typically do not have violent eruptions, and their lava is usually not thick compared to that of stratovolcanoes.
