So in Science at school we are doing this project on the quick and slow changing disasters on the earth. We are currently doing it on quick changing disasters... and I chose volcanoes. I have two questions though, and I can't find the answers to them. This project is due this Tuesday (Tuesday march 10th) and I can't hand it in if I don't have the answers because I really don't want to fail. The questions are:

How hot is erupting lava when it is first exposed to the air outside

And the second question is...

Why does the weather change when eruption happens? Does the weather always change?

If anyone knows the answer, has/knows a good site I could use to pull info from or has an email address of an expert I could ask and get an answer from quickly and use in my Bibliography PLEASE ping me using this thread so I can finish my homework! Thanks so much...Please...hurry!

When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 C (1,292 to 2,192 F).

Found on wikipedia~

And for climate effects from volcano's:

Thanks for those! I will totally use them!

If anyone else has any more (or Eimell finds/has more) Please tell me! Make sure you ping as I don't have much time currently and will not go searching for this thread. Thanks!

@BeingWeirdisCool77,
Found a few references for volcanos. Was pretty interesting overall as I knew not much about volcanos prior.

Turns out the second question's answer is a bit complicated. It depends on the volcano itself as well as where on earth we are measuring the temperature. There are after affects on the entire earth interestingly enough. Of course this should all be explained using scientific terms and with explanations as to why this happen. Not writing the homework answer of course haha.

Here are some links that helped me understand what is going on. I would read them in the following order:

1. Background knowledge on volcanos (not related to the questions, but nice to know)

2. Scroll past the two pictures to start reading. The initial first three sentences help phrase how to think about the question. Helped me at least.

3. This one is very useful, perhaps the most useful. Best read after reading the above though (in my opinion).

4. This is a wikipedia article on one of the volcano phenomenons.

After you have read all of the above, I suggest looking back at the article Eimell linked. It is more dense, but I think if you have the prior knowledge of the above, the article will make a lot more sense!

Also, wanted to point out that this information is all a google away. Learning how to google well is a very useful skill. It sounds trivial, but is actually not.

Thanks! I was googling but...I couldn't find anything useful! Thanks so much for the sites! I will look at them as soon as I get home (I am on my phone currently). Thanks again!

No problem. c:

For googling, it's best to use just key words. To get the results I did, I googled "weather after volcano eruption" I then clicked on 8 out of the 9 links on the first page. And skimmed them to find the four articles that I then proceeded to read and link to you. Googling the entire question, or irrelevant words can make it harder to find what you want.
