What happens to sediment after a few million years?
Regional SpecificsWhat happens to sediment after it forms? Over millions of years, layers of sediment may build up and harden into sedimentary rock. Some of the many forms of sedimentary rock include sandstone, rock salt, and coal. Sandstone forms as sand hardens. … What happens to sediments in a few million years? The Mississippi River carries
What temperature does metamorphic rock melt?
Regional SpecificsRocks of different compositions begin to melt at different temperatures, with initial melting occurring at roughly 650–750 °C in rocks of granitic or shaley composition and approximately 900–1,200 °C in rocks of basaltic composition. Does metamorphic rock melt? Process of Metamorphism: Pressure or temperature can even change previously metamorphosed rocks into new types. Metamorphic rocks
How were the Koolau mountains formed?
Regional SpecificsKoolau Range, mountains paralleling for 37 miles (60 km) the eastern coast of Oahu island, Hawaii, U.S. The range was formed by volcanic eruptions and has an average width of 13 miles (21 km). How did the island of Oahu form? The Hawaiian Islands were formed by such a hot spot occurring in the middle
Is Mt St Helens a hot spot volcano?
Regional SpecificsSt. Helens, include plug-dome elements, the oozing lava staying right above the vent. So, the major volcanoes for our purposes are the quiet, basaltic shield volcanoes of hot spots, the quiet basaltic rift volcanoes of spreading ridges, and the steep, scenic, explosive, andesitic volcanoes of the Ring of Fire. Is Mt St Helens hot spot?
How does Magma cool to form igneous rock?
Regional SpecificsThe magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don’t have much time to grow, so these rocks have a very fine-grained or even glassy texture. How does a magma
What plate boundary caused the Soufriere Hills volcano?
