What feature of the mantle allows movement of the earths crusts to occur?
The proces is called convection
What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
What makes up the earths lithosphere?
The Earth's lithosphere is made up of the crust and the uppermost part of the mantle. It is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below. These plates interact at plate boundaries, where geological activities like earthquakes and volcanic eruptions occur.
In which form do many minerals occur naturally on the earths surface?
Many minerals occur naturally on the earths surface in rock form
Where in the structure of the earth do convection currents occur?
The mantle.
What feature of the mantle allows movement of the earths crusts to occur?
The proces is called convection
Where do volcanos occur on Earths surface?
They occur at plate boundaries (Pacific rim "Ring of Fire") or at mantle hot spots (Hawaii, Iceland).
What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
If the tectonic plates float on a layer of the earths crust what is it called?
The mantle or perhaps you are referring to the asthenosphere, the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
What are the three parts that make up Earths mantle?
mesosphere, asthenosphere, ionosphere
Name three elements that make up most of earths mantle?
The rocks in earths mantel are made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. Iron, calcium, sodium, aluminum, and potassium are also present. The elements occur in rocks as oxides.
Which combination of temperature and pressure is inferred to occur whitin earths stiffer mantle?
High temperature and high pressure are inferred to occur within Earth's stiffer mantle. As depth increases in the mantle, both temperature and pressure increase. This combination of high temperature and pressure allows for the solid rock to exhibit ductile behavior, resulting in the flow of solid material over long periods of time.
Which statement best explains how convection currents can occur in earths mantle?
Convection currents in Earth's mantle occur due to the heat generated from the core, which causes the hot, less dense mantle material to rise towards the surface. As it reaches the top, it cools and becomes denser, causing it to sink back down. This continuous cycle of rising and sinking material drives the movement of tectonic plates on the surface.
What makes up the earths lithosphere?
The Earth's lithosphere is made up of the crust and the uppermost part of the mantle. It is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below. These plates interact at plate boundaries, where geological activities like earthquakes and volcanic eruptions occur.
Where does the Mohorovicic discontinuity occur?
Crust and Mantle.
In which layer of earth does convection occur?
mantle
What feature of the mantle allows movement of the earths crust occur?
The convective currents in the mantle, driven by heat from the Earth's core, allow for the movement of the Earth's crust. This movement results in phenomena like plate tectonics, where tectonic plates interact at their boundaries, leading to earthquakes, volcanoes, and the creation of mountains.
