magma underneath a geyser field is actually relatively close to the Earth's surface. There are different reasons why the magma is so close to the Earth's surface, though many geyser fields are located on the edges
How hot is magma? Is granite formed from magma or lava? How can magma be called a solid under the surface if it is made of molten rock? How is a volcanic island formed? How is magma classified? What keeps magma hot? Where does magma that fills the magma chamber come from? How was ...
The first question to address is: why does the magma erupt at all? The erupting force generally comes from internal gas pressure. The material that forms magma contains a lot of dissolved gases -- gases that have been suspended in the magma solution. The gases are kept in this dissolved st...
How fast does magma flow? Flowing: Flowing is the movement of a liquid downhill under gravity. The movement of water from rivers towards the ocean uses this mechanism of movement. Answer and Explanation:1 Magma flows at up to 60 kilometers an hour on a steep slope with a smooth channel....
High temperatures of over 4000°C cause some of the rock in the centre of the Earth to melt and form hot molten rocks calledmagma. These heats also cause the mantle to behave plastically and portions of it to convect upwards, since it is lighter than the surrounding rock. ...
They can be heated if the rock units that contain them are overrun by a lava flow or if a magma body intrudes above or below. The altered identity of these stones is considered to be "natural."Waxed river stones: These stones were rounded and smoothed naturally by river water. People ...
How Does GPS Work? The Global Positioning System (GPS) comprises over 30 navigation satellites that orbit the planet. These satellites constantly send signals to GPS receivers in smartphones or standalone GPS devices. A receiver then calculates its distance from four or more satellites to determine...
These processes, in an ideal journey from the deepest to the shallowest portions of the volcano factory, consist of: 1) formation and development of magmatic reservoirs; 2) propagation and arrest of magma; 3) emplacement and outcome of shallower intrusions; 4) volcano unrest; 5) eruption ...
C.To work out how the astronauts landed on the Moon.D.To study the rocks gathered from the surface of the Moon.(2)What does the underlined word"This" in Paragraph 2 refer to? A.The collision.B.Theia.C.The Earth.D.The size of Mars.(3)...
How does magma move under the Earth's crust? How do plate tectonics affect ocean currents? What happens when tectonic plates shift? Explain the theory of plate tectonics. What are the boundaries of tectonic plates drawn along? When are transform boundaries of tectonic plates formed? How can gra...
