1) Well, once again, if you imagine that a volume of rock from great depth is moving upward until it gets to that level, it's undergoing a substantial amount of decompression. And because of that decompression, it starts to melt here. We get partial melting that forms magma and magma rises through the lithosphere, and erupts at the surface.

2) Under the Hawaiian Islands, there is a volcanic “hot spot,” a hole in the Earth’s crust that allows lava to surface and layer. Over millions of years, these layers form mountains of volcanic rock that eventually break the surface of the Pacific Ocean, forming islands. As the Pacific Plate very slowly moves across the hot spot, new islands are formed.
