I need help with two questions about the Alaska Gold Rush. I just really really don’t understand it at all.

1. How was the Alaska Gold Rush similar to and different from the California Gold Rush?

2. What were conditions like for settlers in Alaska? How did they adapt to the new environment?

Thanks you guys so much!
That’s not all of my homework. That’s just the two questions out of 15 that I didn’t understand.
But thank you anyways.
