Over the course of many million years, these uplifted sections are eroded by the elements – wind, rain, ice and gravity. These gradually wear the surface of the mountains down, cause the surface to be younger than the rocks that form them, and lead to the types of formations and distrib...
Magmais a mixture of molten rock, dissolved gases, and solid mineral crystals. It originates deep within the Earth’s mantle or rust and can rise to the surface, where it erupts as lava or solidifies underground to formigneous rocks. The composition and behavior of magma depend on its sou...
How does magma form over an active subduction zone? How are igneous rocks formed from a subduction zone? How is basaltic magma transformed into felsic magma? How are volcanoes formed by plate tectonics? How does water create magma during subduction at a divergent boundary? In other words, how...
How are bioclastic sedimentary rocks formed? How are sedimentary rocks destroyed? How are sedimentary rocks different from igneous rocks? On what basis are igneous rocks classified? Igneous rocks are classified based upon their How are sedimentary rocks formed through physical processes?
Many scientists believe that the Moon formed after a planet the size of Mars,called Theia,collided(碰撞) with the Earth.This caused magma to blast out into space.The magma cooled into solid rocks that started orbiting the Earth in rings,like Saturn has.Gradually,those rocks clumped(聚集) ...

For Igneous Rocks:Since igneous rocks are made from magma, we want to melt the chocolate first. Adult supervision is recommended for this step!!In the microwave, heat up a cup of water until almost boiling. Wrap a square of chocolate in a piece of aluminum foil. Place the foil packet ...
So what happens to the magma formed by these processes? We saw that the magma produced at ocean ridges just hardens to form new crust material, and so doesn't produce spewing land volcanoes. There are a few continental ridge areas, where the magma does spew out onto land; but most land...

The name Kimberlite derives from the South African town of Kimberley where the first diamonds were found. 2 Tectonic plate movement Some extremely small diamonds that have been found in ultra-high pressure (UHP) metamorphic rocks in Kazakhstan, China, and Norway. They are thought to have been ...
