Magma formation - Study guides, Class notes & Summaries

What is Geology? - correct answer In its broadest sense, geology is the study of Earth — its interior and its exterior surface, the rocks and other materials that are around us, the processes that have resulted in the formation of those materials, the water that flows over the surface and lies underground, the changes that have taken place over the vastness of geological time, and the changes that we can anticipate will take place in the near future. Igneous rocks for from? - correct ans...

Explain the relationship between the presence of certain elements and types of matter in the solar system relative to distance from the sun. correct answers The suns gravity holds the solar system together, keeping everything from the smallest particles of debris to the biggest in orbit. The surface temperature of planets decrease as the distance from the sun increases. The farther an object is from the sun, the weaker the Sun's gravitational pull, and the slower the object moves in orbit. N...

Praxis 5005 (Science) Kathleen Jasper Purple Book Notes and Information Already Graded A Mantle Is not liquid, but ductile or plastic, which means that some parts can flow under certain conditions and changes in pressure. Composed mainly of aluminum and silicates Crust The outermost solid layer of earth. It is the lithosphere. Core The innermost layers of the Earth. Mainly composed of nickel and iron Inner Core Solid. Temperatures and pressures are extreme. Outer Core A layer of liquid iron...

The more silica in magma, the lower the viscosity. - CORRECT ANSWER False As a result of partial melting, magma originates in __________. - CORRECT ANSWER the mantle and crust When lava erupts at Earth's surface, what type of rock is produced? - CORRECT ANSWER extrusive Pyroclastic debris from a volcanic eruption can include _____. - CORRECT ANSWER ash and cinders Why does magma have a tendency to rise after its formation? - CORRECT ANSWER It ...

apes unit 4 frq with 100% correct solutions 2024/2025describe what happens when two tectonic plates collide in a subduction zone - correct answer in a subduction zone, one plate is pushed beneath the other. a trench may be formed at the subduction zone. explain how subduction leads to volcanic activity - correct answer The plate closer to the core melts and becomes magma, which pushes towards the surface. When the magma reaches the surface, it becomes lava and releases through the crust cau...
