Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
This layer of the crust is made of granite?
The layer of the Earth's crust that is made of granite is called the continental crust. It is less dense and thicker than the oceanic crust, primarily composed of granite and sedimentary rocks. The continental crust is found beneath the continents and is responsible for forming the landmasses we see today.
Which is the most responsible for the formation of new crust at the edge of a tectonic plates?
Diverging boundarys.
Which Earth layer is responsible for filling in gaps left by seafloor spreading?
The process of seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is formed. As the crust moves away from the ridge, it cools and contracts, creating gaps. The mantle beneath the Earth's crust, known as the asthenosphere, is responsible for filling in these gaps through upwelling of magma, solidifying to form new oceanic crust.
Which force is responsible for earth's crust and lithosphere floating on the mantle?
The force responsible for the Earth's crust and lithosphere floating on the mantle is isostasy. Isostasy is a balancing act between the buoyant force of the lithosphere on the denser, more fluid asthenosphere below it. This balance helps maintain the equilibrium of the Earth's crust.
How many elements are in the crust?
The Earth's crust is composed of around 90 naturally occurring elements, with oxygen and silicon being the most abundant. These elements are responsible for the diverse mineral composition of the crust, which varies depending on location and geological processes.
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle
What is the difference between continential and oceanic crust?
Continental crust is thicker, less dense, and typically older than oceanic crust. Oceanic crust is thinner, more dense, and younger as it is constantly being formed at mid-ocean ridges and being recycled at subduction zones.
Are plates composed of the crust and part of the upper mantle?
Yes, tectonic plates are composed of the Earth's crust and part of the upper mantle. The movement of these plates is responsible for various geological phenomena such as earthquakes and volcanic activity.
How do you find the earth's crust compared to the other lyers?
The Earth's crust is the outermost layer of the Earth and is the thinnest layer compared to the others (mantle and core). It is composed of solid rocks and is where all landforms and continents are found. The crust is also where tectonic plates are located, which are responsible for the movement and shaping of the Earth's surface.
What is the of where the crust goes back down into the earth?
subduction zone
What are large chunks of earths crust called?
Large chunks of Earth's crust are called tectonic plates. These plates float on the semi-fluid layer of the mantle and are responsible for movements like earthquakes, volcanoes, and mountain building.
