How oceanic crust different?
Oceanic and Contintental crust are different in composition as well as size and density Continental- granitic/50-100km thick Oceanic- basaltic/ up to 10km thick Oceanic crust is more dense making it subduct under continental crust
Is it true that tectonic plates made up of land and ocean floor?
Yes, there are two types of crust on the Earth, oceanic and continental. The crust under the oceans is, of course, oceanic crust which has more mass than continental crust. Each type is formed from plates of different size and shape.
Why does new crust form but the earth doesn't get larger?
As new oceanic crust is being made in one area older crust is being subducted, (pushed or pulled down), in another area, so Earth stays about the same size.
What happens when new oceanic crust forms?
Actually nothing significant happens after that, the cycle just continues. Are you sure you wanted to know what happens when a new oceanic crust forms or how is a new oceanic crust formed? If you meant how a new oceanic crust is formed then here is the answer>>>> New oceanic crust forms when the divergent plate margins move away from each other leaving a gap, then magma rises to fill that gap, then it cools and turns solid and forms new land. :) I hope this was helpful!
What is the grain size of dacite?
Small to medium grain size.
What is the size of the oceanic?
Oceanic what? Crust? It depends what ocean you are looking at.

What is crustal shortening?
Crustal shortening is the reduction of the size of the Earth's crust through tectonic activities such as those found at a convergent plate boundary. When an oceanic crust collides with a continental crust, the denser oceanic crust subducts beneath the continental crust. This causes the oceanic crust to be subducted back into the mantle and melt, reducing the size of the crust. When two continental crusts collide and neither subducts, the material is being pushed up towards Earth's surface, resulting in mountains like Mount Everest. This causes the crusts to reduce in size.
Is the size of the earth increasing due to oceanic crust being produced?
No. In addition to oceanic crust being created at mid-ocean ridges, crust is destroyed at certain convergent plate boundaries where one plate subducts under another.

Yes, there are two types of crust on the Earth, oceanic and continental. The crust under the oceans is, of course, oceanic crust which has more mass than continental crust. Each type is formed from plates of different size and shape.
Why does the Earth's size remains the same despite of what is happening at the mid-oceanic ridge?
An equal amount of oceanic crust is being subducted at the convergent plate boundaries as is being created at the mid-oceanic ridge.
The relative thickness of the Earths crust is similar to the relative thickness of the?
The relative thickness of the earth's crust would be approximately 1/3 to 1/4 the thickness of an eggshell if the earth were the size of a chicken's egg. (Actually being 7/2 = 3.5 ratio.)
Why does new crust form but the earth doesn't get larger?
As new oceanic crust is being made in one area older crust is being subducted, (pushed or pulled down), in another area, so Earth stays about the same size.
What snacks will have the highest satiety value assuming the calories and relative size are similar?
Slice of whole-grain bread
