Answer:
b. silica
Explanation:
The majority of the volcanoes that form at subduction zones, or convergent plate boundaries, are stratovolcanoes. These volcanoes are also called composite volcanoes. The stratovolcanoes are known to have high to intermediate silica content of the lava they release. The eruptions tend to be periodic, and they are explosive and effusive in general, though there are exceptions. The fact that the lava is high to intermediate in silica content means that the lava is medium to highly viscous. Because of this, the lava tends to trap the gases in it, and as it reaches the surface and the temperature and pressure sharply change, the gases explode, resulting in eruptions that have lot of explosions and propelling of pyroclastic material.

<em>Here's an example letter.</em>
Dear Shenn,
How are you? I haven't heard from you in months. I trust you're well. I'm hoping we could meet this coming Christmas season.
I've recently transferred to another school this semester, and I'm really enjoying it. I'm now on my second year in high school. We have a lot of homework and it has been keeping me busy. Are you also busy in school?
On weekends, I spend time with my family and a new family member, Dobbie. No, he's not my brother. He's a Golden Retriever that I've been asking my dad for a very long time. My parents taught me how to take care of him because they say it would teach me responsibility and independence. Honestly, having a dog is not all fun and games. I sometimes feel exhausted, but I'm blessed that my mom loves dogs too; so we take turns taking care of him.
Before I forget, I'd like to invite you over this Christmas eve. My family will be hosting a party at home and we're very much excited to have you as one of our guests.
I'm looking forward to your reply. I hope you and your family are in good health. Do give them my regards.
Sincerely,
<em>Your Name </em>
