How do scientists explain why if new crust is constantly being formed formed from volcanic materials Earth's crust stays the same size?
The constant formation of new crust at mid-ocean ridges is balanced by the consumption of crust at subduction zones. This process, known as plate tectonics, involves the recycling of Earth's crust. As new crust forms, older crust is pushed back into the mantle, ensuring that the overall size of Earth's crust remains relatively constant over time.
How do continental crust differ from oceanic?
Continental crust is predominantly composed mostly of rock of a granitic composition, higher in silica and aluminum, with layers of sedimentary rock above. Oceanic crust is predominantly basaltic (higher in iron and magnesium), darker, thinner, more dense, and formed from rapid cooling of lava.
How is crust and lithosphere the same?
The crust is the outermost layer of the Earth's surface, while the lithosphere includes the crust as well as the uppermost part of the mantle. In this context, the crust is part of the lithosphere. The lithosphere is composed of the crust and the rigid upper portion of the mantle and is divided into several tectonic plates.
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Continental crust is less dense than oceanic crust, so it floats higher on the mantle. This means that the same thickness of continental crust will displace less mantle compared to oceanic crust. Additionally, continental crust is composed of lighter rocks like granites, while oceanic crust is made of denser rocks like basalt.
What Is the relation between age of oceanic crust and distance from divergent plate boundary?
When oceanic crust is still young, it's relatively warm. The older it gets, the colder it gets. The colder it gets, the less volume it takes in, however, it's still the same amount of matter. This causes a bigger density, thus causing the crust to sink deeper into the mantle.
Why does the earths crust stay the same size?
The amount of crust present on Earth always stays the same. The amount of crust descending into the mantle is balanced by the amount of crust formed at mid-ocean ridges.
What is formed by to rays with the same endpoint?
A line
When huge regions of crust are faulted and uplifted at the same time?
fault-block mountains are formed
Where does new crust forms..?
New crust is formed at divergent boundaries. While an equal volume of new crust is forming the Earth still remains the same size.
What formed Greenland?
Iceland was formed by volcanic activity from the Mid-Atlantic Ridge. It is the point of separation at the Eurasia crust and the American crust. i think Greenland was formed the same way, i looked EVERYWHERE on line and can find anything.
Is the fraction of the south American plate occupied by oceanic crust increasing or decreasing?
It is increasing. The total amount of continental crust remains the same, but new oceanic crust is being formed at the Mid Atlantic Ridge.
Can angles be formed by line segments that have the same end point?
Yes.

What happens when the contential crust collides with the same crust?
When continental crust collides with the same type of crust, it can result in the formation of mountain ranges through a process called continental collision. The force of the collision forces the crust to crumple and buckle, leading to the uplift of land and the creation of large mountain belts. An example of this process is the collision between the Indian Plate and the Eurasian Plate, which formed the Himalayan mountain range.
Why does new crust form but the earth doesn't get larger?
New crust is constantly being formed at mid-ocean ridges through volcanic activity. However, the Earth does not get larger because as new crust is formed, older crust is subducted back into the mantle at subduction zones, maintaining a relatively constant amount of crust on the Earth's surface.
What is figure formed by two rays with the same endpoint?
It could be a straight line, or an angle.
Angle formed by intersecting planes?
A line. Unless the two planes are the same, in that case a plane.
