Spots on Earth’s surface where magma rises from mantle plumes. Hot Spots Spots on Earth’s surface where magma rises from mantle plumes.

Volcanoes grow from the rising magma / lava Volcanoes grow from the rising magma / lava. They often grow high enough to become islands like Hawaii.

Every day on Hawaii…

Pacific Plate slowly moves and new volcanoes form over the hot spot.

The diagram from the reference table shows the Hawaii hotspot and four of the islands from the Hawaiian archipelago. The oldest of these volcanic islands should be the one that is 1) farthest from the hot spot 2) directly over the hot spot 3) moving the fastest 4) creating the greatest quantity of lava

On land HOT SPOTS often boil water that regularly erupts as a geyser.

Hot Spots Heat from the Mantle escapes directly to crust. Creates Volcanoes, Volcanic Island Archipelagos, & Geysers.

The North American continent has a mantle plume rising below an area in the northwest of the United States known as the Yellowstone Hot Spot It’s terrestrial coordinates are best stated as 1) 45o N, 114o W 2) 45o S, 114o E 3) 47o N, 124o W 4) 115o N, 42o W
