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.
How do ocean trenches help explain why crust added at ocean ridges doesn't make earth any larger?
Ocean trenches were discovered as a sign of destructive plate margins. These plate margins cause oceanic crust to subduct below the continental crust at the oceanic-continental boundary, and force the oceanic crust to move down into the Earth's mantle and melt into basaltic magma. As this is happening, magma at oceanic ridges is creating new oceanic crust at the mid-oceanic ridges. Overall, these two processes cancel each other out and so the total amount of oceanic crust is staying aproximately the same. Therefore the Earth is not growing. Hope this helps :)
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.

Is the size of the earth increasing due to oceanic crust being produced?
No, the size of the Earth is not increasing due to oceanic crust being produced. The creation of oceanic crust at mid-ocean ridges is balanced by its destruction at subduction zones, resulting in a process known as plate tectonics where the Earth's surface remains relatively constant in size.
Earth's radius and surface area are slowly increasing to accommodate the new oceanic crust being formed at mid-oceanic ridges - true or false?
False. The Earth's radius and surface area do not increase as new oceanic crust is formed at mid-oceanic ridges. Instead, the creation of new crust at mid-oceanic ridges is balanced by the destruction of older crust at subduction zones, maintaining the overall size of the Earth.

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.

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.
What snacks will have the highest satiety value assuming the calories and relative size are similar?
Slice of whole-grain bread
The relative thickness of the Earths crust is similar to the relative thickness of the?
The relative thickness of the Earth's crust is similar to the relative thickness of an apple's skin compared to the apple itself. Both the Earth's crust and an apple's skin are thin outer layers in relation to the entire object.
