While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.
Plate Tectonics and Volcanoes - National Park Service
WebIn the 1 950’s and 1960’s, scientists discovered seafloor spreading, where new crust is formed at mid-ocean ridges, and formulated the theory of plate tectonics. The basic … WebThe Theory of Plate Tectonics explains the geologic processes that, together with surface processes, produce Earth’s features. In addition, it provides a context for understanding the history of Earth. For example, plate tectonics explains how now-separate land masses can share features that indicate that the continents were once connected. how do you get glow berries in minecraft java
What is a Volcano and How are Volcanoes Formed? - Earth Eclipse
WebVolcanoes often form along where plate tectonics make contact. The friction produced melts the Earth’s crust, creating magma. Extremely heated magma creates pressure and slowly rises to the surface through the fractures between the tectonic plates. Over time it finds its way out through a volcanic vent. WebThe plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a...
