Why is earth not getting larger even though new lithosphere is constantly being added at the oceanic ridges?

Rock creation is part of The Rock Cycle. Rocks are destroyed by erosion--they provide new material for sedimentary rocks. Rocks are created at rift zones in the crust--they are also plowed into the mantle at subduction zones and melt.

∙ 12y agoI should imagine it is because of crust being constantly destroyed at destructive plate boundaries
Wiki User
∙ 11y agoThe earth is incapable of enlarging it self. More specifically, as new oceanic crust is created at mid ocean ridges, old oceanic crust is destroyed at subduction zones.

If new seafloor is being created how does the earth stay the same size?
Because it only gets larger in one direction by getting smaller in another. In the case of ocean ridges, the 'other place' is wherever the crust has subducted into the natle at a plate boundary.
What two types of plates make up the earth?
The two main types of plates are continental plates and oceanic plates. Continental plates are larger, thicker and less dense compared to oceanic plates.
How do the densities of oceanic crust and continental crust influence what happens when an oceanic plate coverages with a continental plate?
Oceanic crust is more dense than continental crust. All that water weight compresses the heck out of the material in the plate and also the oceanic crust contains larger percentages of denser elements such as magnesium and iron than the continental crust which also contributes to it's higher density. This sets the conditions for what happens. The more dense oceanic crust will "dive under" continental crust because it is more dense, and all because of the difference in densities.
Which features form when two oceanic plates diverge?
Oceanic Ridges, when the plates separate magma leaks out through the surface and creates a small ridge or mountain. Repetition of this causes the ridge to get larger and larger as time progresses.
How does the thickness of continental crust differ from that oceanic crust?
There is actually a difference between the thickness of the two. The fact is, however, that actual variance of the Earth's crust is larger than the variance between the continental and oceanic crusts. However, here is the data- The Earth's crust is comprised of layers- the continental crusts are between 35-70 km thick while the oceanic crusts are between 5-10 km thick
What is the relationship between the crust and the lithosphere?
All of the crust is contained within a larger layer called the lithosphere.
Did larger continents broke through the oceanic crust?
No, they float on it.
Why doesn't our planet get larger from sea floor spreading?
As new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
Why is the Atlantic Ocean getting larger than the Pacific Ocean?
The Atlantic Ocean is growing bigger because of two divergent plate boundaries, the Eurasian Plate and the North American Plate. Each year, these two plates move farther and farther apart from the Mid-Atlantic Ridge (MAR). As these plates separate, oceanic lithosphere forms, resulting in the growth of the Atlantic Ocean.
What is the reason why the government keeps getting larger?
Because the population keeps getting larger.
What is the definition for accreted terran?
a piece of lithosphere that becomes part of a larger landmass when tectonic plats collide at a convergent boundary

Is Orion getting larger?
no
Islands and continents are all parts of the?
Islands and continents are all parts of the Earth's crust or lithosphere, which is the solid outer layer of the planet. They are both landmasses, with islands being surrounded by water and continents being larger and connected to other landmasses.
What two types of plates make up the earth?
The two main types of plates are continental plates and oceanic plates. Continental plates are larger, thicker and less dense compared to oceanic plates.
What is ascending number?
An Ascending # is a # That Is Getting Larger. A Descending # is a # That Is Getting Smaller.
What continent has a hole in the ozone layer been growing larger and lasting longer over the last 20 years?
The ozone layer is not growing larger. The ozone hole is getting larger. It is getting larger over Antarctica.
