Which of these are features of most stratovolcanoes?(1 point)
Responses
steep sides near the base with sudden, violent eruptions
steep sides near the base with sudden, violent 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 top with thick, slow-moving lava
steep sides near the top with thick, slow-moving lava
gentle slope near the base with somewhat quiet eruptions
gentle slope near the base with somewhat quiet eruptions
The correct answer is:
- steep sides near the base with sudden, violent eruptions
- gentle slope near the top with thin, quickly flowing lava
To determine the correct answer, let's go through each option and see which features are common for most stratovolcanoes.
1. Steep sides near the base with sudden, violent eruptions: This is a characteristic of many stratovolcanoes. They often have steep sides at the lower part of the volcano, where the eruptions can be explosive and violent.
2. Gentle slope near the top with thin, quickly flowing lava: This is not a common feature of stratovolcanoes. The lava flows from stratovolcanoes are usually thick and slow-moving, rather than thin and quickly flowing.
3. Steep sides near the top with thick, slow-moving lava: This is also a common feature of stratovolcanoes. As mentioned earlier, the lava flows from stratovolcanoes tend to be thick and slow-moving.
4. Gentle slope near the base with somewhat quiet eruptions: This is not a characteristic of most stratovolcanoes. While the eruptions may not always be extremely violent, they are generally more explosive compared to other types of volcanoes.
Therefore, the correct answer is: steep sides near the base with sudden, violent eruptions and steep sides near the top with thick, slow-moving lava.
