Sulfur dioxide which you can smell is a noxious gas

This preview shows page 2 - 3 out of 3 pages.

Sulfur dioxide (which you can smell) is a noxious gas emitted by volcanoes, along with carbon dioxide which is an odorless, colorless gas that can suffocate people and animals. 2. What dangerous gas was released from the Lake Nyos volcanic crater lake on August 21, 1986? (page 197, para 1 to page 197,para 4) A burst of gas, mostly carbon dioxide was released from the Lake Nyos. 3. Where do most geologists think that the Earth's oceans and atmosphere came from and how do volcanoes play a part? (page 198, para 3 to page 199, para 2)) At least part of the earth’s oceans and atmospheres boiled out of the earth’s interior during the period of melting resulting from the conversion of gravitational energy at its dense core formed. Before the concept of plate tectonics, it was thought that volcanic gases were the main source of the Earth’s oceans and atmosphere, which were formed by a long evolutionary process. Now, volcanoes are viewed as recycling the oceans and atmospheres instead of creating them. 4.How are volcanic gases related to the Earth's atmosphere? (page 199, para 3) Before the concept of plate tectonics, it was thought that volcanic gases were the main source of the Earth’s oceans and atmosphere, which were formed by a long evolutionary process 5. How is the gas content of subduction volcanoes different from that of submarine-rift volcanoes? (page 199, para 4) Silica rich magmas have a much more variable gas content and can contain as much as several % gas by weight.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
